Model M-622 is high accuracy resistance decade box with range from 1Ω to 1.2MΩ. Basic accuracy is 0.005 %, best resolution on the lowest range is 10 µΩ. Decade is formed from high stable foil resistors switched with combination of relays. Build-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. Decade is supplied from internal accumulator or from external power line adapter. Both model with RS-232 interface and IEEE488 bus is available.
Resistance decade is determined for calibration laboratories for ohmmeter and multimetr testing and for industry as device for quality testing as well.Decade can be ordered as 19” module for easy assembling into a 19” rack. Module height is 3HE. |
