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
