Cropico CR Calibration Resistor Datasheet0 pages

CR
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 resistors.
