Basic Operation
Setting OVP/OCP/UVL Levels
The OVP level and OCP level has a selectable
range that is based on the output voltage and
output current, respectively. The OVP and OCP
level is set to the highest level by default. The
actual selectable OVP and OCP range depends
on the PSU model.
When one of the protection measures are on,
ALM indicator is lit red on the front panel and
the type of alarm is also shown on the display.
The ALM_CLR button can be used to clear any
protection functions that have been tripped. By
default, the output will turn off when the OVP
or OCP protection levels are tripped.
The UVL will prevent you from setting a
voltage that is less than the UVL setting. The
UVL setting range is from 0% to 105% of the
rated output voltage.

Example: OVP alarm
Before setting the protection settings:
Ensure the load is not connected.
Ensure the output is turned off.
Note
You can use the Function settings (F-13 and F-14)
to apply limits to the voltage and current settings,
respectively. You can set limitations so that the
values do not exceed the set OVP and the set OCP
