Meatest M143 and M143i portable multifunction calibrator
The Meatest M143 and M143i portable multifunction calibrator is a cost-effective solution for calibration of meters with electrical quantities up to 1000 V and 20 A. It offers a basic accuracy of 0.01% in DC voltage required for calibration of 3½ and 4½ digit multimeters. The resistor function covers eight fixed resistors of 10 Ω 100 MΩ.
The calibrator provides thermocouple temperature sensor simulation. It can also be optionally supplied with RTD temperature sensor simulator. Thanks to the small size and low weight of the calibrator, it can be used for field calibrations.
The main application of the calibrator are production lines of panel meters, multimeters, transducers, measuring amplifiers, thermometers and calibration laboratories, where the calibrator can be used as a working standard for calibrations, checks and adjustments.
Options
The RS-232 interface and optional GPIB interface bus provides automated operation and time-saving automatic calibrations. The Meatest M143 is fully compatible with Meatest Calibration Software Package Caliber and WinQbase.
