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
