Disabling the Output
The output of the power supply can be disabled or enabled from the front panel.
When the power supply is in the “Off” state, the
OFF annunciator turns on and
the output is disabled. The
OFF annunciator turns off when the power supply
returns to the “On” state. When the output is disabled, the voltage value is 0
volts and the current value is 0.02 amps.
The output state is stored in volatile memory; the output is always disabled
when power has been off or after a remote interface reset.
• Front-panel operation:
You can disable the output by pressing key. This key toggles between
output “Off” and “On” states.
• Remote interface operation:
OUTP {OFF|ON} Disable or enable the output
While the output is disabled, the range selection keys, the control knob,
resolution selection keys, and adjust selection key are still working. If the
display is in the meter mode, you cannot see the changes of output
voltage and current settings on the display when turning the knob. To see
or check the changes when the outputs are disabled, the display should be
in the limit mode.
