CR Data Sheet
This range of low cost 4 terminal calibration resistors
combine high accuracy, class 0.02, long-term stability and
permanence of calibration in a compact unit.
Constructed using carefully selected low temperature
coefficient Manganin or Zeranin wire, depending upon value, and
mounted to ensure mechanical stability, these resistors will
provide a cost effective addition to any laboratory or workshop.
Typical applications include:
calibration reference, accurate
current measurement, instrument calibration and accurate shunt
resistor.
Main areas of application:
- for tests of measuring
bridges or electrical temperature measuring equipment
- for laboratory setup of a
Wheatstone bridge
- for a defined current
characteristic at a defined voltage
- as shunt resistor for
current measurement
- as part of standard
equipment in research laboratories
A variety of values are available, see table below:
