what about new model? |

A problem with everyone doing cheap chinese multimeter reviews is that nobody really tests the functions, as you do with software white-box testing. Going through the ranges from bottom to top, I found cheezy my AN8008 in fine shape can't read 2mA AC, it's got a flat spot reading zero then jumps up. The 4-count window at zero also can get in your way. The capacitance calibration value is blindly copied from Uni-T, and needs to be different for the particular TVS used in the DMM. Point is we trust these DMM's to work and the firmware is never great on the first rollout. |
