One major flaw of the 71E, which was overlooked until recently, is the lack of an intermediate amps range (4A).
The true RMS converter doesn't work properly under 10% of range, which means there is a dead zone between 400mA and 1A on this meter. It overreads by 10~15% of measurement.
That's a show stopper on a meter where AC current and power measurement is a major feature.
If the majority of your AC measurements are under 400mA or above 1A, you're OK, otherwise buy something else.
All meters in the 71 range are affected and so is the 61E, with an even larger dead zone of 220mA~1A AC.
Sadly, the new UT181A probably also has a dead zone between 600mA and 1A. UT171 models are OK.
I'm surprised that 71E owners didn't pick this up sooner.
