CPC 100
V 3.20
Others: Amplifier - 5
Use the
Amplifier
test card to set the
CPC 100
to an "amplifier-like" mode. In this mode, an
input signal fed into a synchronization input drives the high-current output’s magnitude,
frequency and phase angle.
Select between
I AC
,
V1 AC
and
V2 AC
as synchronization inputs.
To prevent saturation, the output signal follows sudden magnitude changes at the
synchronization input slowly. This smoothening effect delays the follow-up of the output current
up to 250 ms.
Both the "amplification" factor and the phase angle between input and output are set by the user
in the
Amplifier
test card.
Note:
Changes in frequency and phase angle may result in unwanted effects. Both frequency
and phase must be held stable.
Note:
The input frequency is limited to a range of 48 ... 62 Hz.
Note:
The synchronization input is not automatically range-switching, it is fixed to its maximum
value.

Set the amplification factor to determine the ratio between input and output signal.
DANGER
Death or severe injury caused by high voltage or current
Depending on the measured input signal, setting the amplification factor can result in
unintentionally high currents.
►
If the magnitude of the input signal is unknown or uncertain, set the amplification
factor to "0" before starting the test.
►
Set an amplification factor of "0".
►
Press I/O (test start / stop) to start the measurement.
Now the display field shows the measured input value.
►
With the measured input value in mind, enter the amplification factor now.

Acknowledge this entry by pressing the handwheel or the Enter key to start the
