Default A question about the Radio-Shack (Tandy) 22-175b digital multimeter


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 ?

I too have a Radio-Shack (Tandy) 22-175b digital multimeter.
Mine also reads 0.1nF with no input.
I just live with it.
You could push the "Hold/Relative" button, but that sort-of locks-up your other buttons.
