Multifunction calibrator M142 is calibrator of electric quantities for application in calibration laboratories and in production lines where voltage, current, resistance, capacity and frequency meters are manufactured. 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

Built-in process multimeter, standard part of M142 full version, can be used independently or simultaneously with source functions which makes testing transducers, regulators and evaluation units really easy. Using a single instrument you can evaluate output signals of various types of transducers and external sensors (strain gauge, pressure, torsion, strength, etc.), read them directly from calibrator display and use them in your calibrations.

User comfort

M142 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.
