Computer-controlled decade box M642

resistanceprogrammable

M642 is programmable real-resistance decade for industrial use. Its far-reaching 0.1 Ω - 20 MΩ range (22 MΩ upgrade available) can calibrate ohmmeters and other resistance based meters easily. Fine resolution, solid 0.02% accuracy and 5 W load capacity will fit any application. Floating output terminals of M6xx decades allow for AC measurements as well, see datasheet for typical frequency responses. 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: 100 mΩ - 20 MΩ (22MΩ upgrade) (± 200 ppm / year) resolution from 1 uΩ max dissipation power 5 W Temperature: RTD (± 0.1°C / year)
