ESI RS925A

The ESI RS925 is a four-terminal continuously variable decade resistor for the most exacting calibration and test applications.

Specifications of the ESI RS925A include:

High accuracy - 20 ppm + 0.5 mΩ
High stability - 20 ppm + 0.5 mΩ
Resistance from 10 mΩ to 1.1 MΩ
20 μΩ resolution In order to eliminate contact resistance and thermal emf, the RS925D integrates a rheostat. As a result, voltage and contact resistance effects are removed by being effectively added to the input impedance of the measuring instrument.
Low temperature coefficient - as low as 3 ppm/°C
High performance solid silver contact switches
Hermetically sealed, low inductance resistors
Precise fixed minimum resistance
The first 4 decades can be individually trimmed for increase accuracy
