digital equipment changed the game. i love how they have all of these little add ons that makes the accuracy so much better.
You’re a man with a big heart thanks for sharing your knowledge with us which is very valuable for those learning the trade happy thanksgiving to you and your family
That is very nice of you Silvio. I am glad that these videos have been a blessing to you! Have a wonderful Thanksgiving with family!
Craig well done.
Calibration is very important on all digital instruments.
Thanks Nurfet Alic! I appreciate you!
Thanks for this video. I just modified my sman 3 to accept the sunco magnetic manifold strap in place of the metal hook, and decided to do a calibration to complete the makeover. This was just what I needed. Best HVAC channel on CZcams 😎
Thanks Juan!
lol 'modified '
Great video never knew what the test pressure was all about, and or how to test it.
Thanks Austin!
Thanks for another great vid! Nice to see how calibration is done. BTW One more thing: Another reason I know you're a top-notch tech is because YOU READ THE MANUAL..fantastic! I don't think 1 in 10 techs actually read their instrumentation manual. (Also I know you know all the theory and methods from your other vids). Thanks again! [I was once a professor of engineering, you are a professor of HVAC]
Brian, I appreciate you very much. Thanks for your thoughtful comments! Ah I didn't know you taught! Makes sense
Really interesting vid...something new that I learne👍👍 Thanks
Thanks Pedro!
Thanks man I needed this 🤙🏽
Glad to help!
You stay coming through ina clutch
GOOD knowledge sir
Thanks
Thank's Brother for sharing that performance!!!! I will do that when I can afford a set like that, I just have an old what a man by uniweld set of gauges, they read 410 22 and I believe 502 not sure but they work thank's again God Bless.
And that set is fine to work with. I am not recommending but just going over the calibration as I have been asked for this, thanks a lot Jimbola77. May the Lord Bless You Too!
Thanks Jimbola77! I appreciate you!
Good lesson...very helpfull!!!
Thanks a lot!
Thanks for the info.
Thanks Brandon!
Hey Craig! Thanks for the great videos all the time, very knowledgeable and smart! Is there also I way to calibrate the field piece wire less probes temp sensors for air and line temps?

Glad to help!
this is a nice video, try to apply the same method to my sman480 to calibrate, and then realized newer version 480 is missing the adjustable calibration temp button, does anyhone here know why ? thanks
I dont fully trust digital gauges yet but im slowly moving towards them due to built in data logging functions.
Hi, I have been considering investing/buying digital gauges and been reading all the reviews I possibly can between the SMAN460, SM380V, SM480V and Testo. In your opinion what would be the best digital gauges to go with? Any input would be a big help (leaning toward SMAN460 because that’s the one you always have linked to your videos but what is the difference between SMAN460 and SM480V?)
Hello, when I press the atmospheric pressure button on my sman460 it does not goto zero pressures. Is there an adjustment for this?
can you make a video and show how they work. i see a lot of others videos but nobody shows how
I am actually editing some with that tool right now. I will likely post the first of those over the weekend, thanks!
hi I love your post always helpful I do have a question I have sman 460 I calibrate clamps to 32 degrees with ice no problem but when I try to calibrate to Freon r410 I get error clamp temp never matches Freon temp can that be adjusted or how do I fix that
So how much superheat are you reading on your 460 before you press the test button? Is there moving air in the room where you are testing such as the ac running because that clamp will pick up the temp in the room and the bottle temp will still be at the original temp until it catches up. The bottle has to be kept in a room with a constant temp several hours before testing and preferably even longer to be sure, thanks Edward!
thanks for reply I didn't pay attention to superheat the bottle was in room for about 4hrs and ac was not running I will try again the weekend and let the bottle sit in room over night what should my superheat be reading?
The superheat should be under 1 degree away and is the difference between what the sman460 says the sat temp is due to the pressure read compared to the actual tank/room temp. The sman460 doesn't know you are not checking the charge of a running system but will calculate the superheat reading automatically, thanks!
Are you required to use the manufacturer supplied clamp-on temperature probes or can you use any good Type K thermocouple taped to the copper tubing and covered with some thermal insulation? A small, low mass, surface thermocouple would actually provide more accurate line temperature; provided the Fieldpiece device will accept the standard Type K thermocouple.
The temperature of a thermocouple is determined by measuring the milli-volt generated by the 2 dissimilar metals fused together at the thermocouple bead. The voltage produced varies with temperature.
A Mastercool 99103 -A uses type K thermocouples and can be calibrated but I don't know if you are required to use only their probes (technical support has not replied to my question). The Testo devices use a different technology; they use thermistors which are more expensive and a little more accurate.
Thanks for your videos. I really like the one comparing low loss hose connectors.
Thanks A Carter! I have the k-type bead sensors from Fieldpiece at the top row on this page,- amazon.com/shop/acservicetech - and Fieldpiece tools are meant for their brand bead sensors as you see their tabs are different where they connect into the tool. Otherwise you could calibrate any bead type bead sensors on the SMAN, thanks
Hi acservicetech gerkn here again, I'm having a hard time trying to figure out the best set of digital gauges to buy. I have the YJ titan and JB 2 valve but I really want a digital set and can't decide between fieldpiecesman460 or a testo 550. Those are the 2 I look at most, what do you think is a better buy for a first set of digitals......also, do you have to switch the lines for heat pumps in the winter with digitals or does it do it for you? Thanks acservicetech ✌
Both are great quality. I am partial to the fieldpiece though. What do you mean in reference to switching lines? You would have to do that yourelf if you were on the liquid and vapor line for cooling. You would take the low side and move it to the true vapor third port and the high side can get connected to the vapor port. However you can't check the refrigerant charge unless it is in cooling mode and 70 degrees or above unless you have a charging jacket which can work down to 40 degrees outdoor ambient, or unless you are using total refrigerant weight method. Thanks
acservicetech I was asking about switching ports cause somebody told me that with digitals you could leave the low(not the true suction valve) and high side on both king valve cores. I was told the digitals did it for you. This didn't make sense to me since I've been working on heat pumps for about 9 months now. Thanx again acservicetech.
You wouldn't really want it to switch anyway as you would want to see the low side from true suction anyway. I am not aware of such feature on the sman's thanks
could I ask you question ? Do you have any study guide for CFC test ? Thanks you.
I only have the booklet that Mainstream Engineering gives out along with the teacher modules. They may change this test entirely in a year or so and they have been in process developing better questions that have to do with procedures than just memorizing dates and such. Where or who are you taking the Universal 608 through? Thanks ZE Kenzy!
where did you buy the caps for the ports?
How often do I have to calibrate them?
How often do we need to calibrate these sman's
do you have to calibrate each time for a different refrigerant?
You shouldn't need to, once you get the pressure calibrated the programing will convert to saturated temps
Is their a way to calibrate the micron gauge in it?
Then just change to Celsius and your done ! :)
Hi acservicetech, I just have a question not related to this video and I need some advice, so I quit my old HVAC job to go to this other company that was a bigger company and more pay mind you that I'm only 7 months in this trade and after the first day at the end of the day I was given a "non competition agreement " paper stating that if I ever left for whatever reason this company says I can't work in a 50 mile radius of the shop and that if they find out I am breaking this rule in place they would take me to court that . I was wondering if this practice is common ?because the last company I worked for there wasn't really any growth and I don't want to be in a huge company if they are going to put these insane rules in place. Thank you.
50 miles is a long distance. So they don't want you to work if you leave them basically? The county where I work in is only 10 miles wide by 25 miles long. There are at least 50 HVAC companies here. None of us could ever sign a contract like that. Is there a time frame such as 6 months or 1 year such as you can't work for a company withing a 50 mile radius within the first 6 months of leaving. I would explain I just started with you. How can you expect me to sign something like this? I am sorry Rob!
I believe you said in one of your videos you work out of NJ I live in central NJ you might know this company its called Fras Service Experts. I had to quit after the very first day, the document also stated that I couldn't work 50 miles from that particular shop for 12 months.
I actually have never heard of that company. Sorry to hear that! How are you making out? Any new leads on a company?
Its common on companies that don't want you to be a threat and its legally Legit for them to ask you to sign the contract if you did you're an idiot basically lol
Rob Evans and you should stick w the company and gain few years experience before you go run off looking for better pay you think 7 months is enough to get you paid higher all these companies employee's meet at supply houses and hvac related stuff they'll all gossip about you now so if I were you I'd zip up and gain the experience because you are getting paid for it instead of going to a college and paying out pocket to be taught you signed the con tract now you are held liable because your signature is on it agreeing to the contract you want to risk going too work with in 50miles radius then go head and risk it if that company wants to go after you they have every right plus you're on CZcams snitching out companies names that's very bad if I had a employee like you I'd make sure everyone knew about your snitching attitude and make sure no one hired you so you better straighten up and zip your lips and earn your weight
Can you make a video pulling a vacuum with a digital manifold gauge?
I won't use the micron gauge in this meter. I only use the micron gauge close to the unit ports since I have valve core removal tools. This gives me a very accurate micron reading while the pump is running and a good non leaking standing vacuum test, thanks!
Those temperature sensors are thermocouples not RTDs the guage is not measuring resistance of the thermocouples to determine the temperature as you say in the video
So for R22 you have to do the same thing
If you are checking for sat temp of any refrigerant, you would do that. Make sure to keep your temp clamp wire connectors in the correct location on the gauge face and don't switch them, thanks
i have new sman 360 that don't change in to micron .what cut it be?
It could be a leak in the hose or in the SMAN 360. Can you try adding an external micron gauge to the assembly with the SMAN and see what the micron level goes to? You could then take the SMAN 360 out of play and just have the micron gauge and see how deep it goes, thanks!
I bought my Sman4 in June of 2013, they micron part of it, stopped working this month. Pressures are a constant problem, they are not acurate when compere to the my old gauges. I have to recalibrate every time a do a full install, just to make sure (Lost confident on them). Fieldpiece price to repair, because it is out of warranty, $275.00 plus S.H.!!! No Way Jose!!! I`ll buy the hoses to do a vacuum without the gauges as you show in other videos and and dust off my old gauges to do a final tuning on the system.
Got ya, yeah I don't like including any gauge set during my vacuum. Thanks!
Mines is giving me a false reading on low side with out it being connected to anything how can i fix that?pls help
YOUR GAUGES ...ARE THEY DIGITAL? IF SO YOU HAVE TO RE CALIBRATE THEM LIKE IT SAYS IN THE VIDEO. IF YOU HAVE DIAL TYPE GAUGES THEN RESET THEM USING THE CALIBRATION SCREW ON EACH GAUGE.
My guagues got litle rain not much and now they are at -29.9 on both sides, what can I do
Have you pressed and held in the atmospheric pressure button with are the hoses off to zero the pressure?
@@acservicetechchannel thank you so much
Hey does anybody know my atmospheric pressure not reading 0psig for both side
Thanks
Hey Hassan, there is a atmospheric calibration button you will need to press on the bottom of the tool when you have the ports open, thanks
My sman 460 when i do the press test it just say ERROR on both sides
What pressure are you using on the nitrogen regulator?
AC Service Tech LLC. I was using my 410a tank
Pancho Lopez i think hes trying to say that you may have damaged the sensors by using too high of a pressure when leak checking..
How's every ones battery life w the s man 460 seems like my brand new batteries die really fast driving me mad anyone else dealing w same ??
4 months since I got mine and theyre still fine. How long do yours last before dying?
@@lobehold2263 I don't use them as much as I should but I got hurt working and was out for a while but what kind of batteries do you guys use I wonder what they recommend I have Duracell in them now
I used the batteries that came in the package which was duracell. I havent had to change them, I run service all day so theyre used on a daily basis and I always forget to turn them off so they shutdown on their own after 10min
With that in mind I would RMA your SMANs, it seems defective if its eating your batteries quickly. Bad board or something damaged where there batteries sit probably.
Fieldpiece is pretty good on their warranties so it shouldnt be a hassle
Jack benefield
not very clear how many steps, and how many times to press the buttons; why you need to remove the clamp to tank, I don't see any usage.
I'm not recalibrating this thing for saturation temperature... watching this had me crawling out of my skin
