4.4 Input On/Off Control
⚫ The [On/Off] key is used to turn the 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 input off does not place the
instrument in a safe state. Hazardous voltages may be present on all input
and guard terminals. Putting the equipment into an input-off state does not
guarantee that the inputs are powered off if a hardware or software fault
occurs. See the cautions about connecting the test lines before connecting
test lines.
You can press the [On/Off] key on the front panel to control the input status of
the instrument. If the [On/Off] key light is on, indicates that the input is turned
on. The VFD displays the meter value such as voltage, current, power and so
on. If the [On/Off] key light is off, indicates that the input is turned off. The VFD
displays that the load state is OFF.
