You can turn the output of a single channel of the power supply on or off by
pressing the [On/Off] key on the front panel. Press the [On/Off] key, the key
light is on, indicating that the output of this channel is turned on, the VFD screen
displays the voltage Meter value and the current Meter value, and the working
state will switch to CC, CV or CP. Press the [On/Off] key again, the key light is
off, indicating that the output of this channel is off, and the VFD screen shows
that the power supply status is OFF.
You can turn the output of the two channels on or off simultaneously through the
ALL On/Off on the front panel.
The [On/Off] key light is off and turning the output off does not
place the instrument in a safe state. Hazardous voltages may be
present on all output and guard terminals. Putting the equipment
into an output-off state does not guarantee that the outputs are
powered off if a hardware or software fault occurs. See the cautions
about connecting the test lines before connecting test lines.
To prevent electrical shock that could cause injury or death, please
ensure that the power supply and DUT have been connected well
before you turn the output on.
If the power supply has no output after the output is turned on,
please check whether the output lock interface Lock± of the power
supply is shorted. Remove any jumper or shorting clip between
Lock+ and Lock– to output normally. For details, please see
Output Lock Control.
The [On/Off] key is used to turn the output on or off under normal
circumstances. Even if the instrument is in control by PC or the
keyboard is locked, the [On/Off] is still valid.
