Decade Resistance Substituter
The esi RSD925D is a four-terminal continously variable decade resistor for the most exacting calibration and test applications.
For a wider range or more cost effective decade resistor with similar preformance consider our HARS-LX Series
- High accuracy - 20 ppm + 0.5 m ohms
- High stability - 20 ppm + 0.5 m ohms
- Resistance from 10 m Ohms to 1.1 M ohms
- 20 Micro ohms resolution In order to eliminate contact resistance and thermal emf, the RSD25D 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/ degrees 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
