5070 DuctorCal - Micro-Ohm Meter Calibrator

The DuctorCal is a portable calibration instrument suitable for calibrating high current Ductor Testers and Micro-Ohm meters. It contains 5 sets of high current rating standard resistors which simulate the resistance being measured. It has full 4 terminal capabilities with extra large terminals for the current connection. Gold plated terminals are used throughout to reduce contact resistance and thermal emfs (for dc based instruments). It has a substantial maximum continuous current rating but is also suitable for much higher transient/pulse test currents.
