Resistance decade box M632

programmableprecision

M632 is 20 ppm real-resistance decade box with resistance range 1 Ω - 1.2 MΩ so you can calibrate ohmmeters and other resistance based meters easily. Containing some of the most stable and premium foil resistors available, the M632 has just 1 ppm/°C temperature coefficient. Floating output terminals of M6xx decades allow for AC measurements as well, see datasheet for typical frequency responses. M632 also have RTD. Large LCD shows all related parameters including total accuracy. There is no residual resistance or hidden absolute error. M6XX series can show resistance in temperature, distance, force and other units. Complete recalibration is possible in just 10 minutes. All decades' functions can be remotely controlled via RS232, USB, LAN or GPIB interface. This way you can introduce calibration/test stage directly into production line of any resistance based sensor and reduce time required for final quality tests dramatically. Specifications: Resistance: 1 Ω - 1.2 MΩ (± 20 ppm / year) max dissipation power 0.25 W Temperature: RTD (± 0.01°C / year)
