Meatest M151 High-Current Calibrator

The Meatest M151 is an accurate AC/DC current calibrator designed for the calibration of ammeters, current clamps, power meters and transducers. With a current range of 8 mA to 120 A and a frequency range of 15 Hz to 1000 Hz, the M151 offers a complete solution for laboratories and industrial test environments. With accuracy in the 275-400 ppm range and an isolated floating output of up to 450 Vpk, this calibrator is suitable for the most demanding applications.

Advanced current calibration and amplifier functionality

The M151 can be used not only as a standard calibrator, but also as a transconductance amplifier, extending the output current of a multifunction calibrator. This makes the M151 ideal for applications requiring a wider current range.

Thanks to its synchronisation functionality, the M151 can synchronise not only the amplitude, but also the frequency and phase angle of the input signals. This makes it perfect for power and grid quality measurements, where accurate phase settings are crucial.

Calibration of current clamps and transducers

For testing current clamps, the M151 supports a dedicated current coil (151-25), which can simulate currents up to 3000 A. Low harmonic distortion (<0.1%) and high frequency accuracy (0.005%) ensure that measurements remain extremely stable and reliable.

Comprehensive testing capabilities and applications

With its versatile functionality and high precision, the M151 is perfect for:

> Calibration of analogue and digital ammeters (DC/AC up to 120 A).
> Current clamp and transducer calibration up to 3000 A with the 151-25 Current Coil.
> Transconductance amplifier multifunction calibrators.
> Power meter calibration with frequency and phase angle control.
> Industrial tests for grid quality and power management.
