Not a lot of use for AVO 8/9 Meter Movements. Ok for the older AVO's though.
Actually, worse case senario with a stated Accuracy of 1% Measured +-2 Digits, with a 0.1uA resolution, you could be up to +- 0.575uA out.
That's 1% (at 37.5uA) = 0.375uA + the Two Digits which is +- 0.2uA Totel = 0.575uA

Well, the meter I mentioned is an 87. I have an 87V which I use for measuring when checking Avo movements.
DC current accuracy is +-0.2% (+2 digits) with a resolution of 0.01uA.
Your 1% is 0.000375uA, not 0.375uA, which alone is probably more accurate than our eyes can discriminate against, let alone the better accuracy of the 87V.
