M143 Portable multifunction calibrator is cost saving solution for calibration of meters of electric quantities up to 1000 V and 20 A. Basic accuracy of 60 ppm in DC voltage is more than enough for calibration of 3½ and 4½ digit multimeters. Resistance function is covered by eight fix resistors in range from 10 Ω to 100 MΩ, other features are TC temperature sensor simulation and optionally RTD temperature sensor simulation. Thanks to its small dimensions and low weight the calibrator is ideal for field calibrations

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
