Hello,
I has been a long time since I have been here
So I've bought an AN8008 (15€) and 2x UT210E (2x 24€) from banggood (which I like very much).
I've received my AN8008 yesterday and I have a calibration problem with it on the V DC (about 0.1V over).
I have tried with the calibration process without success: it's impossible to have something stable from a 500mV source.
So I have extract my 24C02A with my CH341A and only 3 wires, and I have put some jumpers to switch between program mode(CH341A) and read mode(DM1106EN mode), it works very well:
I have changed some options like adding Temperature in °C (only), changing backlight time and power saving time, and it seems that calibrate with changing manually values works, but a little long to do.
I would like to disable annoying beep sound when changing mode, and slow down a little the display refresh because it seems that it updates too fast and then slowly stabilize the mesured value.
Also I find that the buzzer has a fixed delay which is too long and slow down the bip-mode + add some lag; I can't find if this delay is created by a capacitor or by the DM1106EN (EEPROM?)
And I don't understand why there is a 9.99MOhms limit (whereas the AN8002 has 60MOhms), so I can't check my other DMM input impendance with this one
Last thing is about the mA mode, why it lacks a range ?
I will continue to follow this topic, thanks for all informations in it !
Hoping that someone will post the DM1106 datasheet in english
