Instruction manual

:VOLTage:PROTection[:LEVel]? [MIN|MAX]

This command queries the programmed voltage protection level. When using

MIN or MAX parameters, the power supply returns the lowest or the highest

value that is possible to program for voltage protection level, depending on the

parameter.

:VOLTage:PROTection:S TATe {0|1|OFF|ON}

This command allows you to disable / enable the overvoltage protection circuit.

After power on reset, the overvoltage protection circuit is enabled and the

programmed OVP value depends on the model you have.

:VOLTage:PROTection:STATe?

This command queries the overvoltage protection circuit state. The returned

parameter is always a numeric parameter: 0 (for OFF state) or 1 (for ON state).

:VOLTage:PROTection:TRIPped?

This command queries if the protection circuit is tripped or not. The returned

parameter is always a numeric parameter:. 0 for OVP circuit not tripped or 1 for

OVP circuit tripped.

:VOLTage:PROTection:CLEar

This command allows you to clear the overvoltage protection circuit and it does

not affect the programmed voltage trip level.

After this command the power supply returns to the previous state (output

voltage will have the same value as before OVP was enabled). In this case,

before you clear the protection circuit, you must lower the output voltage below

OVP trip level or increase the OVP trip level above the output voltage value.

Here are some examples of how you work with overvoltage protection circuit

using remote interface commands:

Example 1: Here is an example of how you program the overvoltage

protection circuit using remote interface commands:

VOLT:PROT 5 ;set OVP trip level at 5V

VOLT:PROT? ;responds with programmed OVP trip level (5V)

VOLT:PROT:STAT ON ;enable OVP circuit

VOLT:PROT:STAT? ;responds with OVP circuit state (1)

VOLT:PROT:TRIP? ;responds if OVP circuit is tripped

;(0 if output voltage lower than OVP trip

;level and 1 otherwise)
