Controlling the Output Relay
There are three programming methods to enable the output of a channel
(close the output relay).
•
The APPLy n :VOLTage < value > or APPLy n :CURRent < value >
command both program an output value and close the output relay
on a single channel.
•
The OUTPut n :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 OUTPut n :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 APPLy n :VOLTage < value > followed by an
APPLy n :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 SOURce n :FUNCtion:MODE VOLTage or
SOURce n :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.
