M133C Electric Power/Energy Calibrator
MEATEST
27 Operation manual

The value can be set using numeric keyboard and confirmed by pressing Hz softkey.
The value can be set using cursor buttons or rotary knob as well.
Setting the power in P Harmonic mode (model M133C only)
Mode is used for generation harmonic signal composed of up to 50 harmonic components. All
components can be defined independently for all outputs (3x voltage, 3x current). Beside this
mode allows modulation by sine or square signal.
Each calibrators output (U1, U2, U3, I1, I2, I3) is displayed as a folder. The folder U1 is active
after selecting the Harmonic mode. Next folders are activated by repeatedly pressing „Channel“
softkey.
Pressing „On/Off“ softkey disables (enables) the active output. Only enabled outputs will be
connected after pressing the „On“ button. Enabled outputs are highlighted by blue rectangle above
the output name. After the AC power on all outputs of connected phase units (channels) are
enabled.
Harmonics defined as “
% of RMS
” Harmonics defined as “
% of Fundamental
”
Pressing „Info“ button displays informative window. There is displayed used range for every
output. Range is important for uncertainty calculation, because the uncertainty is not displayed in
mode P Harmonic.
Internal multimeter is not available in P Harmonic mode.
1. Setting the amplitude of voltage (current)
Amplitude can be defined as RMS value (harmonics components are defined as % of
RMS) or Fundamental harmonic value (harmonics components are defined as % of
Fundamental harmonic).

Repeatedly press the “Sel” button (in the middle of cursor buttons) until the voltage
(current) value appears in edit mode (blue background).

The value can be set using numeric keyboard and confirmed by pressing V (mA, A)
softkey. The value can be set using cursor buttons or rotary knob as well.

Output terminals are disconnected if new amplitude is set.

Next folders (outputs) are activated by repeatedly pressing „Channel“ softkey.
