Controlling the Output Relay

There are three programming methods to enable the output of a channel

(close the output relay).

• The APPLyn:VOLTage <value> or APPLyn:CURRent <value>

command both program an output value and close the output relay

on a single channel.

• The OUTPutn:STATe ON command closes the output relay for a

single channel. The last programmed mode and output value remains

in effect.

• The DIAGnostic:OUTPut:ALL:STATe ON command closes all output

relays. The order of relay closure is not guaranteed.

There are three programming methods to disable the output of a channel

(open the output relay).

• Send the OUTPutn:STATe OFF command to open a single channel

output relay without changing the programmed mode or output value

for that channel or affecting any other channels.

• Send *RST to program all channels to voltage mode, 0 volts output,

and open all output relays.

*RST will not change the output mode if

the P/J jumper is set to Jumper Selectable.

• Send the DIAGnostic:OUTPut:ALL OFF command to open all output

relays without changing the programmed mode or output value.

The output relay will also be opened and then closed by a change of output

mode using the

APPLy commands.

• An APPLyn:VOLTage <value> followed by an

APPLyn:CURRent <value> command (or vice versa) will open and

then close the output relay.

All output relays will be opened, and left open, by the following commands.

• The SOURcen:FUNCtion:MODE VOLTage or

SOURcen:FUNCtion:MODE CURRent commands set output mode

for a single channel and opens the output relay for that channel.

Other channels are not affected.

• The *RST command performs a reset and leaves the output relays

open on all channels (the command also programs all channels to

voltage mode, 0 volts output unless the P/J jumper is set to Jumper

Selectable).

• The *TST? command performs a self-test and leaves the output

relays open on all channels. Programmed output modes are restored

following the self-test.
