11.5.2. Read Over-Voltage Tripped
This query reports if an over-voltage protection fault has occurred. If a fault has
occurred, it may be cleared by turning the power supply output on again (see the
OUTP:STAT ON command, section 11.2.3)

Responses:
11.5.3. Set Under-Voltage Limit
The under-voltage limit keeps the voltage setting from being less than a certain value.
If the actual power supply output (or remote sense point) drops below the UVL, no
fault is reported and the supply continues to operate in the constant-current mode
(you may use the foldback protection to report a fault when this occurs, see section
11.5.5)
The voltage limit setting, made by the front panel encoder or the VOLT command (in
section 11.2.1), must always be higher than 105% of the UVL setting. Likewise, the
UVL setting cannot be made higher than 95% of the voltage setting.
The UVL setting may be viewed on the supply front panel by pressing and releasing
the OVP/UVL button twice.
Syntax:
Parameter: nn.nn will set the UVL to a value in volts
