Precision Resistance Decade Box Real resistors switched by relays Resistance range 1.000 00 Ω – 1.200 00 MΩ Accuracy from 20 ppm / 0.01 ºC Custom units and time sequences No residual resistance Six language packs M632 is 20 ppm programmable real-resistance decade box for calibration laboratories and flagship of Meatest's resistance calibration. Containing some of the most stable (and expensive) foil resistors available, the M632 has just 1 ppm/°C temperature coefficient and can be used for AC applications as well, typical frequency responses are listed below. M6xx series was made to make resistance calibration as easy as it gets. Large LCD shows all related parameters including total accuracy. And there is no residual resistance or hidden absolute error so you don't have to calculate it by yourself, accuracy you see is what you get. And that's not the only thing that firmware sorts out for you. Would you like the resistance shown in temperature units? Distance? Force? RTD and user function will do this for you. Complete recalibration? Ten minutes and off you go. 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.
