@mmmmmmm522 Hello Jye Tek, I bought the M162 kit and modified it to M162-10. I did both open and short calibrations. All resistance values are OK, but resistors between 16 and 24Ω shows about 15Ω. Due to a wrong measurement, my oscilloscope shows a clipped signal on the positive half wave on TP1 (pin 14 U1D). For other values, I did not observe a clipped signal. This looks like a problem in the software when switching the measurement range late. When downgrading to the basic version of M 162, there is no error with a limitation Thanks in advance
Hi, can you check the open signal amplitude (peak-to-peak value) with an oscilloscope at the test terminals? This value should read about 0.5Vpp. If this voltage is good, check the AC voltage at V2 (TP20) while the test terminals are shorted. This voltage should read about 0.5Vpp too.
Bought this, but I can only set 100Hz and 1kHz, can only measure down to 1uH. Do I need a firmware update? PN of the lower board is 109-16206-00B1, otherwise it looks identical to the unit in this video.
The boards of M162-10 are the same as the standard model. Some parts are different. The firmware is different too. We will publish instructions for how to convert the standard model to M162-10 soon.
Was your M162-10 purchased or was it converted from a regular M162 by yourself? Did you check the meter with other value resistors? Did all of them show wrong readings?
Thanks for the testing. We sent you a new version of the firmware. A test mode was added which helps to verify the signal level and amplifier gain. Please try the test mode with the resistance between 14 - 26 ohm and see if any abnormal can be observed.
You are right. We found a bug that caused mistakenly detection of the signal level. Corrected firmware sent to your email. Thank you for helping to uncover the problem!
Hello, can you please explain the process to enable the 10Khz option and to measure small inductances in the order of nH as shown in your promotional video? My unit just has 100Hz and 1Khz option, I found the M162 to M162-10 mod instructions on your site, but theres no reference to the firmware software nor the process to load it... Please clarify/explain. The unit looks great but I cant measure small inductances as shown in the video, which was the reason why I purchased it. Thanks
new version, does it already have the battery charging board integrated?

Good afternoon, tell how denotes the U2 EPROM memory microcircuit because it is
not ndicated in the diagram
very impressive, is it possible to calibrate this meter or are its measurements fixed?
Yes it is. But unfortunately this hasn't been impremented in the current firmware.
@@JyetechVideo well im glad to see that its possible. this product is very impressive especially for the price.

OK, thanks!
The instructions for how to convert an M162 to M162-10 has been published. Please see jyetech.com/m162-10-lcr-meter/
Hello, by resistors from 16 to 24 Ω M162-10 shows wrong values about 15Ω. How can I correct this error? Thanks

Hello, both AC voltage are about 0,5Vpp/10 kHz

The firmware is here jyetech.com/m162-10-firmware/. The instruction for how to change the firmware please refer to the manual of M162.
@@JyetechVideo mod performed and firmware updated, a bit tricky to set the interfase, but worked flawlessly. Thanks!
Hello,
can you measure resistors from 14 to 25 ohms? My M162-10 shows about 15 ohms when measuring these resistors.
Thank you in advance
