The M143 Portable multifunction calibrator is a 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 fixed 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.


M143 was designed for automated calibrations at production lines of panel meters, multimeters, transducers, measuring amplifiers, thermometers, and calibration laboratories where the calibrator can be applied as source of standard value for calibrations, verifications and adjustments of units under test.

This calibrator comes in three models:

M143i with a 2 Amp/1000V range

M143 with a 20 Amp/1000V range

M143 20A/1000V including Caliber Software.


This item comes standard with factory calibration certificate, user manual, PT100 Temperature Probe, standard power cable, red/black test leads, and RS232 cable.


Available Options:

1. RTD Temperature Sensor Simulator Extension $1079

2. 140-50 Current Coil (x25, x50 turns) $719

3. GPIB Extension $669
