The measurement of contact resistance is done by applying a DC current of 0-100 Amps. and measuring the voltage drop across the contacts. An ammeter and a millivoltmeter (Micro-ohmmeter) are provided measuring the current and resistance. A lamp indicates the AC supply position. A variac is provided for adjusting the output current from 0 to 100 amps. Fuse for protection against overload is incorporated. CRM Range: 0.1 micro-ohm to 19999 micro-ohm in two ranges.Input: 240 V ±10%, 50 Hz. ±5%.Output: 0-100 Amps., DC, continuously variable.
