Response Setting
p. 30
Under certain conditions, such as when you select square waves for the signal source or
when there is a large amount of inductance in the load wiring, the output waveform may be
distorted or oscillation may occur. In these situations, you can reduce oscillation and the
distortion of the output waveform by setting responses (rise and fall times). You can set four
levels of responses in both CV and CC mode (as explained below). The PBZ provides its
fastest responses when it is set to the factory default settings.
Setting Procedure
Generally, the output waveform is distorted or oscillation occurs when the PBZ is in CV mode
and is connected to a load that with capacitance and when the PBZ is in CC mode and is
connected to a load with inductance. After connecting the actual load to the PBZ, select the
appropriate response from the four response levels that provides the most stable response.
p. 86
Use to set the responses. The selectable values are the rise and fall times for
rated loads. Rise and fall times are affected by the load impedance.

Influence on the response speed of V-LIMIT (the voltage limit) and I-LIMIT (the
current limit)
p. 66
The response speed of V-LIMIT (the voltage limit) is interlocked with the CV mode voltage
response setting. The response speed of I-LIMIT (the current limit) is interlocked with the
CC mode current response setting.
When you are using the PBZ in CV mode, set the CC mode current response setting to
set the I-LIMIT (the current limit) response speed. When you are using the PBZ in CC
mode, set the CV mode voltage response setting to set the V-LIMIT (the voltage limit)
response speed.
