Turning the Model 2450 output on or off

You can turn the Model 2450 output on from the front panel or by sending remote commands.
Turning the Model 2450 output off does not place the instrument in a safe state (an interlock
is provided for this function).
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the Model 2450
while the instrument is powered on. Turn off the equipment from the front panel or
disconnect the main power cord from the rear of the Model 2450 before handling cables.
Putting the equipment into an output-off state does not guarantee that the outputs are
powered off if a hardware or software fault occurs.
When the source of the instrument is turned off, it may not completely isolate the instrument from the
external circuit. You can use the output-off setting to place the Model 2450 in a known, noninteractive
state during idle periods, such as when changing the device under test. The output-off states that can
be selected for a Model 2450 are normal, high-impedance, zero, or guard.
See "Output-off state" in the Model 2450 Reference Manual for additional details.
Using the front panel:
Press the OUTPUT ON/OFF switch. The instrument is in the output-on state when the switch is
illuminated. The instrument is in the output-off state when the switch is not illuminated.
Using SCPI commands:
To turn the output on, send the command:
:OUTPut:STATe ON
To turn the output off, send the command:
:OUTPut:STATe OFF
Using TSP commands:
To turn the output on, send the command:
smu.source.output = smu.ON
To turn the output off, send the command:
