MEATEST M143 Portable Multifunction Calibrator

MEATEST_logo_PL

The MEATEST M143 Portable multifunction calibrator is cost saving solution for calibration of meters with ranges up to 1000 V and 20 A. Basic accuracy of 65 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.

Calibration domain

The MEATEST 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.
RS-232 and optionally GPIB interface allow for remote control of the calibrator and time saving automated calibrations using SW package CALIBER/WinQbase.
