PROMET R300 | R600 Specifications

Product catalog summary

General Description
High-precision ohm meters designed for both stationary and portable use in switching stations or industrial environments. They feature an adjustable test current of up to 600 A, with one current output and three voltage measurement inputs, allowing simultaneous resistance measurement at three points. When used with an ACTAS test system, both static and dynamic main contact resistances can be determined.

Specifications

Current Source Outputs: 1 output, PROMET R300 up to 300 ADC, PROMET R600 up to 600 ADC, with an output voltage of 5 VDC and adjustable step value of 1 A.
Voltage Measurement Inputs: 3 inputs with measuring ranges of 100 A, 300 A (PROMET R300), and 100 A, 300 A, 600 A (PROMET R600). Voltage ranges include 20 mV, 200 mV, and 2 V, with compensation for thermal EMFs.
Resistance Range: Up to 250 mΩ with accuracy ≤ 0.1% of range.
