- Secondary Ignition waveform analysis and relative compression testing is performed in this video using a uScope from AESwave. Here is the kit I was using www.aeswave.com...
There is also a basic kit where you can use your amp probe and other accessories from other scopes. www.aeswave.com...
For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.

I have been working in the motor trade for 20 years and I have learnt quite a bit from watching your videos Paul keep them coming please regards Marc
+marc wingfield thanks brother
Just discovered your channel and am already learning a lot from watching only a handful of your videos.
Thank you for your hard work and dedication.
Welcome! Glad you found me. Looking forward to hearing from you along the way
i purchased the uscope about a year ago and find it addictive ,i am a retired Mechanic and love using it on my vehicles....its simple and a quick way to check things out..found a bad injector on my jeep this way...and i also use it at my Electronics bench to look at digital and analog signals....cool tool
no need for that: just unplug the injectors one by one and look for no reaction.
@@josepeixoto3384 What if you can't reach the injectors because of a super charger or intake manifold is in the way? Things are not always easy, we need alternative ways of testing in the field. Keep working, Keep learning.
@@themanthemyththelegend1392 Cylinder cut out is cool on a ford or chevy product. Although if you work on a European product and it doesn't have injector cutoff, ignition coil cutoff, or can't do a simple power balance test then what?
P.s I already know the answer to that one.
Every time I watch you. I learn something new…. thank you very much
thanks for using the uScope and showing us some of its features!
I see this video is more than a year old but just in case you hadn't figured it out yet you can zoom in on waveform. Press the A button to place the scope in HOLD mode, then you can change the voltage scale and time base from the bottom menu and move left and right under the Horizontal tab in the main menu.
Pretty Cool Paul, not a bad scope, the spark kv jumped high indicating high resistance at the beginning of current flow through the plug indicating a problem exterior to the combustion chamber.
hot soak after run hood closed in summer heat on restart often causes secondary winding breakdown of insulation in coils and other electronics.Old school trick on bikes and older motors was to pull plug wire half way off plug which would increase energy of spark at gap to clear fouled plugs Surprised you didn't do a cylinder efficiently test at idle in gear to rule out low cylinder compression. Good testing .
Thank you posting this, Paul. I have been in the market for a scope. A Snap On Verdict is way out of my budget. The U Scope is exactly what I need for home use.
SUBSTANTIAL Sir ScannerDanner 🙏
Good Morning 🙏 🌄 Take care and have a great day Sir ScannerDanner
From Nick Ayivor from London England UK 🇬🇧
Man that's awesome that the Uscope can do all that. Thanks for the video......sorry I'm 6 years late 😆
Just ordered my uScope, can't wait to get it and try it out. Currently have a modis but can be a little big and bulky at times. Love the videos and info.
I have the distributed by airtex and comes with all I see yours has and a cop inductive pick up.
thank you for the video agian hit all the good info. really liked the running compression test. I have to use mine more often to become more familiar with it.
Thank you Paul for another great video !
I have the feeling that sometimes I learn more here that at uni.... thanks...
Luis Alejandro Luna Villamizar thank you Luis! You keep watching and I'll keep them coming.
I see you using that little dso more often it seems to be a really cool scope what are your thoughts on it im looking at the 2channel version for just easy quick testing
Also if have you have time im using an autell ms906bt im looking at the mp408 scope for it but i dont know if an amp clamp will work with it there are two available from hantek who makes the leads for the mp408 maybe even the mp408 itself not sure about that. could you help me out? With my problem i seem to be in an uniformed state about amp.clamps for automotive use and im learnning more all the time
I keep running into stumbling blocks i never really got any in depth training on scope use and im trying to get skill with them so i can be more competitive amd sharpen up my electrical diagnostics
I really havent had much trouble diagnosing problems with out one but these days i seem to be getting more bus problems in my bay so im adapting my tool set to get more involved the demands on me are getting higher and i need help
Compression seems perfect Paul, good job :)
Paul, the buffer has 4,000 data points and they are coming out with a update in early 2017 so you can scroll thru it. That was the first flaw I found with it when I bought mine ! I also don't like that it does not have scales per division so you don't have to do the math,. It is a nuisance ! Check out CAutomation's post below. He has some good info too ! All in all it is a very high quality scope for the price !
Thanks for the info. Billy R!

Hey Paul, im almost certain it was a carbon tracked spark plug.
The way the burn line bleeds down like it did. Not gradually, but when the burn line KV started higher and bled off.
Great work though.
+Kevin Mowdy thanks kevin!
Love your work. Think you may have sold me on a uscope for a little toy to play around with.
I've seen this video before some time way back and it's funny because I saw that waveform and immediately I saw signs of carbon tracking or spark jumping outside the cylinder when spark jumps around the 3kv it's normal but when it jumps early like around 6kv, it's definitely outside of the cylinder. In my opinion.
scanner danner thank you for helping me,i dot not speak english but learn everything just seeing. brasil
Now that was very cool. I got to try me a bit of this.
Its hard 2 think about how much more misdiagnosis that is possible i will make in the future , but with practice and consistancy good things can and will happen
Great work Paul as usual....many thanks
hi scanner ACIS ignition is coming out advanced corona ignition man i cant wait to see those wave forms
Sheffield used to sell an rpm/peak kv tester that would have made that a lot easier.it used a hook end that inductively picks up voltage and gives a digital readout value.
Hi Paul was wondering how an amp clamp probe rated only at 60amp can handle Relative compression test? I have one similar rating but thought I need a 600 or 800 amp probe to do it? Mine is the hantek 65 and I'm using my electronics desk top lab scope
Hey ScannerDanner, Love your vids man! I need one of these.
I did like it. On to the next one!
Great videos by a great Auto tech
+treluvsjay1 thanks!
Is there a way to illuminate a faulty coil pack with the scope or is it just reading off the wires alone? I'm watching all your vids over and over, btw. New to the scope scene.
It depends on the car and the type of ignition system. What are you working on?
Thank you sir
There is some odd waveforms for sure. Storage scopes helps a lot. I remember the days of parade.
That's a cool little tool. Thanks
Thanks for the great vids!! I'm learning a lot!!!
Why does the U-scope not need some type of protection from the high KV? Where you use attenuators on other systems.
For this case, as long as you don't open a HV circuit there's no need for protection because all the U-Scope is reading comes from an induced pulse, a magnetic pulse coming out of the wire, I mean you are not unplugging any spark plug. If there's a leak through a defective wire (a crack for example) then you need to avoid any physical contact at that very point which at a darker hour could be seen as a little spark (electric arc).
If you were to check the primary side even though it's 12v power to coil and injectors the windings in the coil and injectors can have a high snap back voltage spike as coil field collapses so you'd want to protect scope w an attunement 10x or 20x depending on your scope. Mine is rated to 300v but Pico and uscope are rated lower so need attunement
Is there a way to pause or record the waveform to memory other than taking a BMP screenshot? A trigger record function would be nice when you were trying to capture the cranking waveform. Running from the driver seat back to the scope after cranking would be frustrating without a video camera to record the event. Seems a bit silly to run from the car to engine just to see a waveform for a few seconds before it is rewritten by the next screen.
I think if you set trigger right and set to single mode it should catch it and not overwrite it
Wish they had a 2 channel version of this to see cam & crank relationship. Currently AESWave only offers a 1 channel version.
You can buy newer 2 or 4 channel on Amazon. Just search DSO.
Not from AESWave though which is designed specifically for automotive use. They design the firmware and components to handle massive voltage spikes. Automotive DSO's are different in a way.
No they are not. I have theirs scope and other pocket 2 channel scope. They only programmed presetting with V, Time, Trigger for different applications. Something you can change and set yourself. Hardware is same as all other DSO201 scopes. I will make video in couple days about it.
Astro Camper
I would be very interested to see that. Please notify me when it's up.
over the years on lead systems,caught many easily and also if non resistance s.plugs used incorrectly. I would lift all ht boots partially off s.plugs to increase resistance. Bad lead or plug would drop out,if incorrect plug it would improve firing while running and snap throttle. Showed up well on scope too. Miss parade and raster on the old shop scopes, no provision on new scopes I have
my vehicle would miss when cold and till engine temperature reaches 90 degrees celcius, after that butter smooth. I changed plugs, checked injectors and cylinder compression. could there be something else I am missing ?
Yes, it could be an intake manifold gasket leak. Once the engine warms up the manifold and cylinder head expand and stops the leak. With the engine cold use a squirt gun filled with water and direct it at the manifold gasket area. I actually have a few videos where I show finding a vacuum leak with water.
Another cause is early stages of headgasket failure. Are you adding coolant at all?
Hello. In some video i saw the scope in mv not in kv it will cover it? Thanks
That was a good one
beautiful sound of this engine v6
+alexandro ferreira v8
+Bartek Kaczyński ok , thanks this beautiful sound of the engine . here in Brazil has very little of these engines
not many of those in Poland neither, unfortunately!
+Bartek Kaczyński
in Brazil too, almost no
True, but nothing like the sound of an air cooled 911 flat six! (2.7, 3.2 etc)
Hey I followed exactly how you hooked those up but I have an autel MS919 and I did get any kind of read. I turned my car on and still no oscillation of waves.
Uscope diagnostic tester thanks.
thanks for all your vids man!
Thank you!
$429 for an oscilloscope! I thought these were super expensive, I might have to ask Santa for one of these kits.
The ‘ol Five Oh.
Hard to believe this vehicle is still on the road
Hi Byrne. How are you. The problem I have it just how to read those diagram and know whats the fault .
Scanner
Dinner. This me again about GMC Chevy vortec put brand new spider that was the problem .OK but I change plugs wires icm rotor cap before I fount out it was spider think I might have fould plugs but it ran so good for about to weeks it don't have power it's supposed to got a miss slightly going to change plugs they told me gap plugs at 45 but the vin W says 60 .I'm yesterday smell of gas was really bad like it was flooding I gunned it couple times straighten up on smell but acted sluggish skittle do you think it's TPS or plugs I'm going to change anyway or EGR valve you helped me in time of need on my truck I appreciate every thing you have done oh and it's a 1994 4x4 chevy GMC vin W s10 LS
Did you ever actually diagnose this one? I've had similar spark lines after replacing plugs, wires, cap and rotor. Would be great to know what was the actual cause.
Could be
Plug gap to big
Primary issue?
Fuel air mix, lean higher spark line shorter burn line and visa versa rich
Mechanical issues
Compression
Vales
Blocked exhuast
Etc
Intake
do you have a video up about a miss and hesitation off idle when pulling out in drive ? i have a 1998 chevy express 3500 5.7. you steered me to the fuel pump replacement and i did change that and is working fine . only the above mentioned problem now. also it doesnt always miss or pull out with hesitation. also if i let it sit more then a day it takes a while to start up / have to crank it a few times. and i have no codes showing up either. thanks for your time and effort. thank you in advance. i tell everyone i am around working on cars to check out your videos instead of the joe shmoes back yard mechanics videos, thanks again
Most of the cars here come with 4 plugs but one Honda City model came with 8 plugs. What advantages could it have over the 4 plug cars?
That looks like a handy little gizmo to keep in your toolbox. Isn't the 'u' in the name meant to be pronounced micro as in micro farad, meaning it should be called microscope which seems to make sense.
ACE Auto Electrics its not, they have another tool called a uActivate that has nothing to do with time bases and so on. good thought though. Thanks!
very unique video using the uscope scannerdanner. however, could that secondary misfire be from a bad coil base on the waveform you got and not the wires?
Secondary ignition has so many variables. Plugs and wires did fix this issue. Could there have been a coil problem? Yes but not in this case.
paul danner I wish you a merry christmas new year with a lot of health prosperous peace and much happiness , that 2016 is for you and your family a better year than 2015. 'm your fa you are my biggest supporter and resaltar who love the usa if I could change myself for USA
I would love to have hum book on your oscilloscope
SCANNERDANNER, Does the Firing order give more horsepower depending on the firing order sequence? Why would different cars use a different firing order for what reasons any advantages?
cylinder numbering and mechanical layout is what dictates firing order
I was going to say same as CAuto about pressing the A button ,and adjusting the scales but not sure what software you have on that u scope . I have a uscope but it doesnt have the new version that I can press the A button and zone in. I am planning on calling Scott so aes wave can install latest version , and will hopefully have a can low and can hi testing option.
How do you do this test on a drive by wire system? You should also do a video where you analyze the wave form, I seen a video on CZcams that does this but the resolution is not the greatest is on a channel name tst seminars by a guy name Mac.
good video man well explained. Ive seen some of your videos with the picoscope too. Have you ever used hantek scopes or know are they any good for working on cars?
sorry man, never used a Hantek scope
You can do a relative compression test with a 60A probe?
Yes. Set it to the 60 amp scale (10mv/a)
2v screen will equal 200 amps
2 second time base (total screen time)
Drop test
Well i got rip off on a grag that put a fule pump in and the pump was out all was needed was to be put in and got charg for 3 hrs
awesome video and good info as always thanks for sharing .
Please use it more often and in different scenarios like this you just shoot to see if I buy it
paul danner good night , you sell book over waves of ignition , admission manifold vacuum and pressure transducer cylinder in Portuguese ?
+alexandro ferreira I do and it is available at www.scannerdanner.com
Thank you!
thanks for posting :)
Thanks for watching!
Is it possible that this can be caused by a faulty injector too? Maybe more info on the way the waveform looks?
no sir, here is what a secondary ignition pattern will look like from a lean condition czcams.com/video/NXrd1fYwj1o/video.html
love it!
is the new Snap On Modis Ultra 2014 can be use labscope to plugged secondary ignition test lead to test vehicles? if not is there any option as my local snap on dealer says its not going to work. Only applicable to old Modis ultra and Verus.
+Roderick Tuazon It will work with any of the following. I have all three of them and they will work with ANY lapscope

For a beginning diag tech, would you recommend a pocket scope like this or a used truck brand scope for similar money? Thanks!
Not sure what a used truck brand scope would be but any scope is better than no scope don't you think? There are just some things you cannot do without one.
Why were you only getting readings on some of the plugs sometimes?
+JasonMTG Nevermind, should've finished watching!
+JasonMTG no problem, thanks!
i see you hooked the ground to battery negative. is this necessary, or could I ground to anything like the engine block?
anything on the block is fine my friend
Will the Uscope show a cylinder with low compression? In other words, can I hook this up to my F150 and determine which cylinder has low compression?
Yes, you can do a relative compression test with the uScope. But you will not be able to determine by the scope alone which cylinder is which because it is only one channel.
ScannerDanner Ok. Thanks for the helpful reply.
JackOfAllTrades - you can introduce a known fault by removing a spark plug. Then you just need to know the cylinder # and firing order
Ha ha! Nice little pocket scope!
Another great video. Can I do the same thing with my vantage pro? I cant seem to get the waveforms to freeze on the screen after they pass the trigger.
psychofish21 you can. On your trigger settings, set it to "manual" trigger, then increase your trigger level to where it only hits that level during a snap throttle event and it will hold it on the screen just like I showed here.
+ScannerDanner , thanks sir.
Why the scope pause every time ?? It's not clear
I believe you are asking why the scope automatically paused itself?
Because I had a manual trigger set to a very high voltage that is only met when I snap the throttle. Manual trigger is the key. Watch my picoscope basics videos (part 1 and 2) I cover this in there and it doesn't matter if you have a pico. It is universal scope stuff. Thanks!
Hi , I’ve a bench top oscilloscope on order, can / will it do this sort of things on cars or dose it have to be one special type for cars ?? Manny thanks 👍
That's what I use works fine, it's a rigol DS1054Z.
the car specfic oned like picoscopes are great for a number of reasons. I'll be getting one at some point
Thank you for your videos Scanner Danner, really helpful!
If you were looking for a scope for your commercial shop, would you buy a 4 channel scope or an 8 channel scope?
4 channel, an 8 channel is good for training, but almost never needed in diagnostics
@@ScannerDanner so a 2 channel would be enough?
@@ScannerDanner and thank you for responding, I really appreciate it!
@@jorgematias5504 sometimes :-)
Well im sold on a U scope. That is a crazy powerful tool to have at your disposal and in such a small package. DO you think you're gonna carry this more with you on these field work jobs rather than a 4 channel scope depending on the problem? Or do you still think having the multi channel capabilities are too valuable?
+FBobby I carry all of my stuff, so it really depends on the situation. thanks for watching!
Oh ok. So in this case it was just a good time to show the capability of the uscope.
+FBobby you got it and my subs have been asking for me to show a lower cost alternative, so this was it.
Great video! However, can this test (or a similar one) be preformed on a ford C.O.P engine like the 5.4 V8?
+Kris Sondors absolutely, you just need a different adapter. It's called a paddle probe and comes with the uScope master kit.
+ScannerDanner Awesome! Thank you for the response. Is the paddle probe the only way or is there another way if I don't have one? Thanks again!
+Kris Sondors the paddle probe is one of many COP adapters that are used with a scope to acquire a secondary ignition waveform.
The other units I have used are the following:
Pico www.aeswave.com/Coil-on-plug-COP-and-Signal-Probe-for-Secondary-Ignition-p9335.html
Wyseprobe www.aeswave.com/15-inch-WyzeProbe-for-Secondary-Ignition-and-COP-p8764.html
paddle probe www.aeswave.com/COP-Secondary-Paddle-Lead-Capacitive-p9151.html
How would a pocket oscilloscope work on a relative compression test if it would?
Didn't I show that in this video? At the end?
Paul
Was wondering why you couldn't access mode 6 on this obd2 compliant vehicle?
+Richard Gill mode 6 is hit or miss
I bought your book. Thank you. But that was the worst demo of a uscope you had to reatach the lead to the wire twice almost every time . Whats with that?
that wasn't a uScope issue, that was a scope issue in general when trying to view secondary ignition, especially when performing snap-throttle testing and trying to trigger off of the high firing line
@@ScannerDanner Thank you for the responsive. You are the best.
That's a neat scope. When I use my pico scope and I scroll back through the 32 frames from a captured coil waveform, some of the frames look great with a burn time showing relatively flat and a nice nose at the end, but other frames show the burn time sloping upward or sloping downward. Should all 32 frames of a capture show good characteristics or is it normal for some of them to show good and some of them to show not so good? Another example, on one of my tested coils, I've got 31 frames showing the burn line and 1 of the frames showing no burn line at all. I'm assuming that's a problem but I'm confused as to why I see so many good frames and then 1 bad frame on the same coil capture.
normal characteristics of secondary waveforms my friend, but when you see no burn line on one frame, is that coupled with a misfire you can feel? Then I would believe it. If it is NOT misfiring, your most likely getting a poor signal with your pickup at times
@@ScannerDanner Ah, good info, thanks. This '96 Grand Marquis has an intermittent misfire on different cylinders, and high stft under load on both banks. No CEL. Sounds like maybe I caught one of those intermittent misfires on that frame showing no burn line. One of these days I'm going to be as good as you at this stuff.....one day......👴
For the Wyzeprobe is this work for both COP and Secondary Ignition Test? if i order this probe is it includes cable to link to my New Modis Ultra to Wyzeprobe? if not, can u help me and send me what kind of cable i need to purchase. thinking them also how to ship to Australia
+Roderick Tuazon yes, and yes, just let them know you are buying it for the Modis (banana style plugs)
Thanks for share =)
how can the scope recognise low compression or pressure changes?
+goreziad do a search on my channel on how to perform a relative compression test I have 3 or 4 videos showing this procedure
can you use that scope for looking at MAF, cam, and crank sensors, O2 sensors, all that kind of stuff? and where can I buy that scope?
Yes, but can't do correlation tests since it's single channel
When you look at scope graph what you are looking for? the graphic scope to see is working or not ?

Do you know that you are a scholar went to comes to fixing car that's why scholars I've been asking lots of questions lol thank you for Caring about my education when it comes to cars and you have been kind to me and you had been willing to help me if were things were easy for you and you would help me a lot more and I appreciate once again thank you
Big fan first of all .... Is it possible to have a compression problem if motor runs flawless for 5-10 minutes and then goes left ... Idle seems steady on dial but big stumble felt in wheel at stop lights ( especially if it's a long light to wait. ) Power is 50% gone .. Puff puff out exhaust pipe ... Dash lights flicker but no changes under load (ac ,etc) crazy but car runs perfect cold ... I have no cats only straight pipes and tried to unplug o2 and ran worse ?? Could a faulty o2 rob all that power even at wot ? You would swear it still had clogged cats but I removed them ( shattered guts inside). I assume rich condition maybe killed o2 then killed my cats ? Would poor compression show up only warm temps ? That's all I'm super worried about , anything else like sensor related would be better news. Thanks
+Kevin Duprey I don't think so, what are you working on? that would help.
Also, are you absolutely positive that when you mash the pedal all the way to the floor that it does not improve. If you answer is no, then I agree, no reason to look at the O2 any further for this issue.
Have you considered a faulty alternator diode? I have a video on this called "alternator diode testing".
As a test, unplug the alternator (smaller connector, not bat wire) after it starts acting up and see if it improves
+ScannerDanner .. Good info , sorry it's a BMW 1997 740il .. Will check that recommended video , I'm guessing I'm looking at multipal issues . Money is tight or I would have purchased o2 anyway I do have following codes po155 po150,po135,po156,po130,po136,po330.. Also a crazy p1166 ?? Not even BMW code ?? I'm positive if you mash the pedal it's acting like I'm pulling a semi and falls on its face ?? Again no cats on car , clear cat back flow .. I'm catching up watching your videos everyday and thanks for helping ...
Why does everything ha e to be snap throttle?
because we are packing air into the cylinder which increases compression pressures and makes it harder for the spark to jump the air gap. So it is a stress test in a way
mechanics will pull the wheel well skirts out of these engine when changing plugs and then the plugs can get soaked with water while hot.
Dude I don't know what it is but every time that I have something that I am unsure of it seems like you make a video of it within a few days lol. I am working on a 08 Subaru impreza 2.5I that has a constant misfire on 2 cylinders @ idle and hi rpm and the waveform has a downward slope just like yours I thought it was a secondary misfire but wasn't positive, anyhow I told him to put a coil on it because he already did plugs and wires. It still got the misfires. I am going to do a relative compression test this week. Any suggestions? If I cant figure it out can I bring it to the school?
Awsum video I don't do a lot of ignition scoping and this video helped me a lot!!
Thanks
JOHN HUFNAGEL I'm not back until October my friend.
John do you have a scope file of it? Might be able to help.
Man I need a job there your always on vacation Lol No problem Iam sure I will figure it out, Have a good time off work ScannerDanner
busjockey1
I didn't save the file cause I was pretty sure that the coil was the problem from what I thought was a secondary misfire but I will have the car back this week for round 2.
I'm always working John, more now than ever. I'm just not in the classroom as much
How can i get this uscope device

+scannerdanner can u do some videos on ignition scooping using the verus pro, to also include your personal set up. I have purchased a verus pro about 1 year ago and I'm ready to start using ignition scooping. I trued it several times but got really funky wave forms. a lot different looking then the wave forms on your ebook and videos. so any video doing the different options with yoyt verus would be sio helpful. I've already spent sceral giurs googling and watching videos but no luck.
+phillip zanders for sure. in the mean time I have an 11 hour Verus series training course on my premium channel. Email me through my website and I'll give you a free month coupon. mention this post.
+ScannerDanner yes I got a coupon for pay pal and used it on your channel like 7 months ago. I watched the verua series twice it was soo good. unfortunately money is tied up till the end of September. then im going to do year subscription. I think u have the one of the top 5 best automotive repair and information channels BTW. if I wasn't living in Alaska I'd take your classes personally rather then watch them. your ebook is very good, glad I purchased it. but like I said any more verus ignition scoope videos and some tutorials would be awsome and help soo much since I dont have a teacher or even a technical school that teaches how to use it(I checked so I know)
did he say 1999 mercury mistake? lol
Kris Lizana he did the mystique we can a mistake
Ernests great uncle lloyd. "That's it mistake, go on bust up all your toys (cinder blocks 😂) daddy el getcha new ones...daddy's rich!" czcams.com/video/ls82Pj7XeGc/video.html
When he said mercury mistake it reminded me of this video so thought I would share...you'll laugh.
Hi Paul,It's a really nice video.I am an Automotive engineer working in Saudi Arabia and I have being in the filed 25 years ago.
in the last video for ignition coil . you said,at 8:17" that the spark plugs would be wet and it needs a minute to dry". I am working in Toyota disturber in Saudi Arabia. in Toyota, there is a signal feedback will be sent from secondary coil to computer to confirm that the spark differently is be generated. if the computer is not received this signal from a particular cylinder ,the computer would cut the fuel in this cylinder ......this is following to emission regulations which are be applicable in USA. I do not know if your Honda is the same or no. in addition, I would like to communicate with you about my Technical Articles which can be consider as On-Job-Training. if you want , I will send it . thanks again for your Video.
