Does anyone have a cct diagram for a CROPICO PW3/E resistance bridge. Could be useful on LF/MF for Impedence measurements.

This one in new condition althought a few years old. It works well for R measurements with 90v DC applied down to 0.0001 Ohms

Must substitute RF voltage and see how it performs with antenna impedence measurements on LF/MF

There is another one availabe at low QRK

tnx de G3KEV
