Hi, I recently bought the AN8008 tester at Banggood, I've made some changes to the tester, as recommended at
https://www.jackenhack.com/aneng-an8008-modify-for-better-accuracy-faster-readings/ .
I did some measurement tests on low currents: in DC current there are no problems, the measurements are correct, both on mA DC and on uA DC, then I tried to measure in AC current at 50Hz network and 230VAC, using a resistor in series with the tester, in the uA AC range there are no problems, but in the mA AC range the measurements start from 7 - 8 mA AC with errors even 50%, then as I increase the current, it becomes more and more precise.
When I try to measure currents of 1, 2 or 3mA AC, the tester remains on 0 mA AC.
I ask if you have also found the same defect of the tester and if you have a solution about it. I have other multimeters and the problem with these obviously does not show up but they work properly, thanks for the help.
