Meatest Model M133c is a three or single phase electric power/energy calibrator in a compact housing. It can supply the unit under test (UUT) with single-phase accurate AC voltage and current with calibrated phase shift or DC voltage and current.

Output voltage is adjustable in five ranges up to 600 V and output current in six ranges up to 30 A. Simulated electrical power can be set independently in each phase. Frequency can be set from 15 Hz to 1 kHz and resolution from 0.001 Hz to 0.01 Hz. The calibrator is equipped with 5 1/2 digital DC meter with DC ranges of 20 mA or 10 V for direct calibration of different types of transducers.

The Meatest Model M133c calibrator provides two types of defined distortion of the mains sine waveform output signal. The first distortion is based on adding a certain amount of harmonic or interharmonic spectral components up to 5 kHz. The second type of distortion is based on amplitude modulation of the sine wave output signal by adding sine or square wave modulation signal in frequency range from 0.001 Hz to 50 Hz.

Maximum modulation depth is 30 %.
