Model M631 - Precision RTD Simulator Brochure

Model M631 is high accuracy RTD simulator with range from 16 Ω to 400 kΩ. Basic accuracy is 0.01°C, resolution is 0.001°C. Decade consists of highly stable foil resistors switched with combination of relays. Apart from RTD temperature sensor simulation (temperature setting in degree of Celsius or Fahrenheit) the M631 can be also used as a standard resistance decade. Instrument can be controlled via RS232, USB, LAN or GPIB interface. Decade uses internal power supply with very low noise level. SImulator can be used also for AC application. Typical frequency response is in the datasheet.
