The Orbit OCM631 is a precision Resistance Decades with free setting of resistor value within 16 Ohm and 400kOhm and base accuracy of 0.003%. The best resolution of the lowest range is 10 µOhm. The instruments contain high stable foil resistors with extremely low temperature coefficient switched by low thermal voltage relays. The internal microcontroller calculates parallel and serial combinations of internal firm resistors in order to achieve best accuracy of the selected value.
The build-in software contains function of RTD temperature sensor simulation with parameters according to IEC (DIN) or US standards. The temperature can be set in degree Celsius or Fahrenheit. Remote control via RS232, USB, GPIB or LAN is available.
The Decades are sophisticated instruments with their own recalibration procedure which enables to correct any deviation in resistance without mechanical adjustments.
They are designed for checking parameters of resistance meters, regulators and process meters using external resistance sensors.
