1 Basic information
M133C Three (single) phase power calibrator is a multifunction calibrator, to be used primarily as
a standard for calibration laboratories. It can be used for calibration of any measuring instrument
which measures voltage, current, power, energy, phase and frequency. The calibrator is equipped
with a built-in multimeter, which can be used simultaneously with output functions. Transducers
of various types, regulators and sensing units can be therefore checked without the need for
additional measuring instruments.
M133C model is equipped with special functions for power line voltage analyzers testing. It can
generate calibrated harmonic and interharmonic distortion, fluctuation harmonics, flickers, ramp
signals and others.
M133Ci model is delivered without the option of harmonic/interharmonic functions.
Basic features of the calibrator include generation of calibrated AC voltage in the range of 1 V
to 600 V and DC voltage in the range of 1 V to 280 V, DC and AC current in the range of 5 mA to
30 A. Phase shift for all outputs (3x voltage and 3x current) can be set independent for each
output. The best accuracy of the calibrator is 0.025 % for voltage and 0.035 % for current. Internal
ranges (voltage 10, 30, 70, 140, 280 V and 600 Vac, current 0.3, 1, 2, 5, 10 and 30 A) are suitable
for accurate testing of power transducers. Maximum frequency range is 15 Hz to 1000 Hz.
Internal multimeter with 20 mA, 10 V and 10 kHz (0.02 % accuracy) can be used to measure
normalized signals coming from transducers.
The calibrator includes many other features which facilitate easy use. For example the possibility
to save the actual setting into the internal memory, currently displayed uncertainty of the output
signal, calibration and testing procedures etc. The concept of calibrator control and indication of
its status is based on flat luminiscent display, which provides all necessary information. The
calibrator is controlled by opening menus on the display and selection from menus. Frequently
used functions are assigned direct-control keys. The calibrator comes with standard IEEE488 bus,
RS-232 serial line and Ethernet connector, which allow the calibrator to be controlled from a PC.
The calibrator can easily fit within calibration systems featuring Power software support.
Calibrator is available in Three or Single phase version. Both versions look the same. The only
difference is that the Single phase version doesn’t contain channels 2 and 3. Single phase version
can be upgraded to Three phase version by the manufacturer.
