As I had remarked, a good RMS meter on a known impedance, on a frequency it's spec'ed for. The setup shown is neither.
Also: For low-level AC measurements you invariably need active rectification. So your meter will never be directly connected (or through a series resistor) to the source.
- jacquesm 11y agoAgreed. The guts of that meter register 37uA for full scale (I found some specs), at 10V that's an internal resistance of 270K so probably it really is driving the meter directly. For 8 V that translates into 0.25 mW of power produced, which I don't think will be charging any cell-phones.
