Instruction manual

78
Let’s say that the output voltage is lower than 10V. No load connected.
VOLT:PROT 10 ;program OVP trip level
VOLT:PROT:STAT ON ;enable OVP circuit
If OVP circuit is already enabled, you don’t have to enable it again!
VOLT 10 ;OVP circuit tripped
When output voltage becomes equal or greater than OVP trip level (here
is 10V), OVP circuit trips. Output is disabled and Over Voltage message
will be displayed.
VOLT 5.5 ;decrease output voltage level
VOLT? ;returns programmed output voltage (5.5V)
Still output is disabled and Over Voltage message is displayed (because
you didn’t clear OVP condition yet)
VOLT:PROT:CLEAR ;clear OVP condition
Power supply returns to previous state before enabling OVP circuit. It
will display 5.5V and 0A. Since you didn’t disable OVP circuit, ovp
indicator will be displayed.
Example 4: Here is an example of how you clear the overvoltage
condition by disabling OVP circuit, using remote interface
commands:
Let’s say that the output voltage is lower than 7V. No load connected.
VOLT:PROT 8 ;program OVP trip level
VOLT:PROT:STAT ON ;enable OVP circuit
If OVP circuit is already enabled, you don’t have to enable it again!
VOLT 15 ;OVP circuit tripped
