PBZ
165
Troubleshooting
App
The output is unstable.
Symptom
Items to check and possible remedy
The output voltage or output
current fluctuates.
Is the remote sensing feature turned on?
When you are not using remote sensing, set SENSING to OFF in the CONFIG
settings.
Does the sensing cable or load cable have poor contact, or is the cable broken?
Turn the POWER switch off and check the wiring.
The output voltage is offset
from the voltage that the PBZ
was generating when it was
turned on.
Has 30 minutes passed since the power was turned on?
Warm up the PBZ for at least 30 minutes.
–
There is a large amount of
output noise during external
control.
Are you using two-wire shielded cables or twisted pair cables to connect to the
external voltage or external resistance?
Use two-wire shielded cables or twisted pair cables to connect the PBZ to the
external voltage or external resistance; keep the cables as short as possible.
Does the external voltage produce a lot of noise?
Use an external voltage that produces as little noise as possible.
See
The output response is slow.
Symptom
Items to check and possible remedy
The output voltage or output
current response is slow.
You can set the response.
Use the CONFIG settings to set the response.
See
There are glitches in the output.
Symptom
Items to check and possible remedy
There are glitches in the
output waveform when output
is turned on or at the transition
between sequence steps.
When you combine signal sources, glitches may be produced because of the
differences in the responses of the signal sources. You can reduce these glitches
by increasing the response setting. You can also eliminate output glitches by
registering the necessary waveform as a user-defined arbitrary waveform and
selecting just the AC signal for the signal source.

Settings cannot be loaded from preset memory.
Symptom
Items to check and possible remedy
Settings cannot be loaded
from preset memory.
Have you switched the PBZ from bipolar mode to unipolar mode?
Are you loading a memory entry that was saved in bipolar mode when the PBZ is in
unipolar mode?
Set the PBZ to bipolar mode.
You cannot load memory entries that were saved in bipolar mode when the PBZ is
in unipolar mode.
