3. Press [Shift]+[Recall] (Save) to save the settings. In this case, the prompt
“Configure Success” will appear on the interface. If [Shift]+[Recall] (Save)
are not pressed, the configured parameters will be invalid.

protection will be triggered, the power output will be immediately OFFand
will appear on the LCD screen.
Clearing overvoltage protection:
In the case of overvoltage protection, disconnect the tested object at first. Press
[shift]+[M4] on the front panel (or send the command “PROTection:CLEar”) to
clear on the front panel and exit the OVP mode.
Overcurrent protection (OCP)
 Peak overcurrent protection (Peak OCP)
When the output current exceeds the set peak current, Peak OCP will be
enabled, and will appear on the LCD screen. When the RMS overcurrent
protection is disabled, the OC status in the status register will be reset.
Clearing overcurrent protection:
In the case of overcurrent protection, disconnect the tested object at first. Press
[shift]+[M4] on the front panel (or send the command “PROTection:CLEar”) to
clear “Peak OCP” on the front panel and exit the Peak OCP mode.
 Rms OCP
When the output current exceeds the set Rms current, Rms OCP will be
enabled, and will appear on the LCD screen. When the peak current
protection is disabled, the OC status in the status register will be reset.
Clearing overcurrent protection:
In the case of overcurrent protection, disconnect the tested object at first. Press
[shift]+[M4] on the front panel (or send the command “PROTection:CLEar”) to
clear on the front panel and exit the Rms OCP mode.
