3.4 Output On/Off Control

You can press the [On/Off] key on the front panel to control the output status of
the power system. If the [On/Off] key light is on, indicates that the output is
turned on. The VFD displays the meter value such as voltage, current . And
displays the operating status such as CC/CV and so on. If the [On/Off] key light
is off, indicates that the output is turned off. The VFD displays that the power
supply state is OFF.
The [On/Off] key is used to turn the output/input 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.
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.
