HM8112-3S: Temperature measurements with scanner card HO112 (ID #657)
Because of the bistable relay of the scanner card HO112 (HM8112-3S), which have virtually no thermal stresses, it is very suitable for temperature measurements. Particularly accurate measurements are possible with platinum resistance in four-wire arrangement. With the use of thermocouple wires, the influence of the reference junction is observed. It is possible to input the temperature via the keyboard, the use of the internal temperature measurement, compensation in ice water or the use of an isothermal block.
