Hi All,
I bought the above meter not long and realized this meter has 2 issue really make me puzzled. I had used other meters like fluke and tenma, but this one, I cannot figured out why. Anyone do you have any experience or used this one care to enlighten me?
First issue:
Jumpy probe, reading cannot settle quick and sharp. I switched to my fluke probe, it show the unit was working good. So the probe is quality or compatibility issue? Or something else?
Second issue:
The microampere measurement accuracy has blown out of my expectation. A microampere function that cannot measure microampere accurately seriously? Refer to my table of measurement, the microampere measurement with this meter is so way out of the range compare with my reference meter(which is a little better in accuracy). It is many multi times over the expected values.
If I have a circuit power with 2.13mA. According to the spec and the calculation, I should expect my measurement should fit within the tolerance below? No?
Tolerance range
=% of reading + count * resolution
= 1% * 2.13mA + 2 * 0.1uA
= 0.0215mA
Aside that, this meter couldn't measure 0.6mA to 1mA, a shadow zone. Damn god regret bought this meter.
Your advise is greatly appreciate
