users need to calibration in both short circuit and open circuit. from the video, i see it's correct in short circuit. But what is your meaning? numbers can change randomly occurred after open circuit calibration?
I did open and closed calibration
The device is operating chaotically.
and it’s not convenient that after turning off the calibration needs to be done again
I will make a video and post it.
jumps 0.00 ** it turns out the device is 0.00 and not how I wanted 0.0000
Sorry for not being able to reply to the post in time, the problem has been feedback to the engineer, I will reply to you as soon as the result is available.
