Product description

The Multifunction calibrator M140 is a calibrator - tester for use in calibration laboratories as an electrical standard of voltage, current, resistance, capacity and frequency.


Load capacity of the voltage output is 30 mA - enough for most high-consumption analogue power-meters.

Installed harmonic and non-harmonic shape signals allow for testing meter sensitivity to distorted signals by a signal with various crest factor.


Frequency modes, suitable for calibration of multimeters and time bases of oscilloscopes, have adjustable 6-digit frequency, amplitude and duty ratio of the output signal.


The calibrator can measure temperature with TC and RTD temperature sensors to show it on display or use for cold junction compensation.


Built-in multimeter - Tester

Internal multimeter with basic capability to measure VDC, IDC, R and F process signals is standard part of both M140 and M140i.

Meter functions can run simultaneously with source functions to measure and evaluate output signals of various types of transducers as well as external sensors (strain gauge, pressure, torsion, strength, etc.).
Another useful feature of the multimeter is 10-point automated UUT test.

The calibrator can be set to source an output signal in up to 10 predefined steps and compare UUT's output with predefined specifications and optionaly operate the UUT or a switch using a relay output.

The results are then displayed directly on the calibrator screen in a comprehensive table with PASS/FAIL sign at each step.


User comfort

M140 calibrator is focused on user friendliness making calibrations simple and straightforward.

Each function has its dedicated chunky button and all relevant details including total relative accuracy are shown on large LCD.

Range of adapters for easier terminal connection and automation possibilities, relative deviation feature that can help you with UUT error calculation and easy keyboard-controlled adjustment procedure are just a few examples to prove the point.


GPIB and RS-232 interfaces are present in both versions so the calibrator can be operated via remote control or used in WinQbase/Caliber software calibration systems including the CamOCR module for automated optical UUT readouts.


More information

The M140 is a 35 ppm AC/DC multifunction calibrator for multimeters, ammeters, ohmmeters, temperature meters, transducers, regulators and many more.

Built-in multimeter further increases user comfort by simultaneously reading and evaluating UUT output signals.
