The Time Electronics 5070 Micro-Ohmmeter Calibrator incorporates 5 sets of high current standard resistors that are used to enable precision calibration. 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. It has a substantial maximum continuous current rating, but can also be used with much higher transient/pulse test currents. The internal resistance standards are high quality manganin types with long term stability and temperature coefficients.
