front panel is cleared and the instrument exits protection status.

4.3.4 Under Voltage Protection

Users can enable the UVP function and set the instrument warm-up time (Warm
up time), protection limit (Level) and protection delay time (Delay). When the
voltage (i.e., the Meter value) is lower than this protection limit and the warm-up
time, delay time are exceeded, the power supply will enter the UVP state.
How to Set
1. Press [Shift]+[Recall] (Protect) keys and enter to Protection menu.
2. Press the up/down key or rotate the knob to select Under Voltage Protection.
3. Set the protection status, warm up time, protection Level and the delay time
in sequence, and press [Enter] to confirm.
Clear UVP Protection
When UVP protection occurs, the instrument responds as follows:

Instrument output is off.

The instrument emits an alarm sound every 3 seconds.

The main interface status bar displays the UVP icon.
To clear the UVP and return to normal operation, firstly remove the conditions
that caused the protection fault. Press [Shift] +[Esc] key (or send the command
PROTection:CLEar) to clear the protection status. The message displayed in
front panel is cleared and the instrument exits protection status.

4.3.5 Under Current Protection

Users can enable the UCP function and set the instrument warm-up time (Warm
up time), protection limit (Level) and protection delay time (Delay). When the
current (i.e., the Meter value) is lower than this protection limit and the warm-up
time, delay time are exceeded, the power supply will enter the UCP state.
How to Set
1. Press [Shift]+[Recall] (Protect) keys and enter to Protection menu.
2. Press the up/down key or rotate the knob to select Under Current Protection.
3. Set the protection status, warm up time, protection Level and the delay time
in sequence, and press [Enter] to confirm.
Clear UCP Protection
When UCP protection occurs, the instrument responds as follows:

Instrument output is off.

The instrument emits an alarm sound every 3 seconds.

The main interface status bar displays the UCP icon.
To clear the UCP and return to normal operation, firstly remove the conditions
that caused the protection fault. Press [Shift] +[Esc] key (or send the command
PROTection:CLEar) to clear the protection status. The message displayed in
front panel is cleared and the instrument exits protection status.

4.3.6 Set Maximum Voltage/Current/Power Limit

The voltage output can be adjusted between 1% and 100% of Vmax, while the
current output and power output can be adjusted between 0% and 100%. You
can set upper limits for the output voltage, current, and power in the Protection
