I have a Radio-Shack (Tandy) 22-175b digital multimeter.
Wen I use it to measure capacitors it do not do it's 0 before measuring,
even without any wires plug to it there is alway a .1 nf reading, there
is only two trimpots on the pc board, how can we reajust to have 0 ?
Any body would have the schematic diagram for that meter ?
What is the spec for measuring capacitance?
With a decent ;-) general purpose meter like say a Fluke 110 the maximum
resolution on capacitance is 1 nF, so a 0.1 nF error is neither here nor
there.

Hello
They say in the booklet a resulution of 1 pf, well it seem that it's not true.
I will look for another meter for real 1 pf resolution.
Thank everybody.
