Turn the Model 2461 output on or off
You can turn the Model 2461 output on from the front panel or by sending remote commands.
Turning the Model 2461 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 2461
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 2461 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 2461 in a known,
noninteractive state during idle periods, such as when you are changing the device under test. The
output-off states that can be selected for a Model 2461 are normal, high-impedance, zero, or guard.
See
(on page 2-97) for additional details.
