Operation manual
Setting the power in modes Pdc High I and Pac High I (Three phase version only)
In this mode current outputs of all channels are connected in parallel using optional adapter.
Current range is increased three times.
Voltage terminal Channel 1 are used in high current modes.
Power setting is the same as in modes Pdc Basic a Pac Basic.
Setting the power in modes Pdc Extended and Pac Extended
Modes allow independent parameter setting for all calibrators outputs (3x voltage, 3x current) For
each output you can define amplitude (V or A) and phase shift (º). Phase shift is relative to the
internal reference.
The main power value displays summed power calculated as sum of power of all connected
channels. It is not possible to change this value directly. Color of this value is black.
Each calibrators output (U1, U2, U3, I1, I2, I3) is displayed as a folder. The folder U1 is active
after selecting the Extended 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.
Picture displays state after AC power on. Both outputs of main phase unit are enabled, active is
output U1.

Setting the amplitude of voltage (current)
The main power value can be changed by changing the amplitude of voltage (current).
Repeatedly press the “Sel” button (in the middle of cursor buttons) until the voltage
(current) value appears in edit mode (blue background).
