Precision Resistance Decade • Resistance range 1.00000 Q - 1.20000 MQ • Resistance accuracy +/- 30 ppm • Temperature coefficient < 1ppm/°C • Operating voltage 200 V • Simulation of RTD temperature sensors • Pt simulation accuracy +/- 0.01 °C • User defined curves (conversion tables) • RS232 (optionally USB, IEEE488, LAN) Model M632 is a precise resistance decade box with range from 1 Q to 1.2 MQ. Basic accuracy is 0.003 %. Best resolution at the lowest range is 10pQ. Decade contains stable foil resistors with low temperature coefficient switched by low thermal voltage relays. Built-in software contains function of RTD temperature sensor simulation with parameters according to IEC (DIN) or US standards, temperature setting in degree of Celsius or Fahrenheit. Instrument can be controlled via RS232, USB, LAN or gPiB interface. M632 is sophisticated instrument with its own recalibration procedure. The procedure enables to correct any deviation in resistance without any mechanical adjusting. Decade box is designed for checking parameters of resistance meters, regulators and process meters that use external resistance sensors for non-electric quantity measuring.
