Sorry!

What is 1% of 37.5uA? How do you get 0.000375uA?


Also Fluke 87V is a 4.5 digit (19999 counts) quality DMM at a cost of £400

Accuracy will be +/- 0.075uA (0.2%) + 0.02uA (2 digits) = +/- 0.095uA, or near enough +/-0.1uA

Resolution is not the sama as accuracy!

I am sure a new Fluke 87V will meet the OP's specified requirements at only £400 plus a re-callibration every few months
