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 V and the current value is 0.02 A.
• 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 . This
key toggles between output Off and On states.
Remote interface operation
NOTE
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.
Output On/Off
OUTP {OFF|ON} Disable or enable the output.
