Language Dictionary 47

VOLT:PROT

This command sets the overvoltage protection (OVP) level of the power supply. If the output voltage exceeds the OVP

level, then the power supply output is disabled and the Questionable Condition status register OV bit is set (see "Chapter 4 -

Status Reporting"). An overvoltage condition can be cleared with the OUTP:PROT:CLE command after the condition

that caused the OVP trip is removed. The OVP always trips with zero delay and is unaffected by the OUTP:PROT:DEL

command.

Query Syntax [SOURce]:VOLTage:PROTection[:LEVel]?

[SOURce]:VOLTage:PROTection [:LEVel]? MIN

[SOURce]:VOLTage:PROTection [:LEVel]? MAX

Returned Parameters <NR3> VOLT:PROT? returns presently programmed OVP level.

VOLT:PROT? MAX and VOLT:PROT? MIN return the

maximum and minimum p rogrammable OVP levels.
