OUTP:REL

Do not install or program the Agilent Relay Accessories if the power supply maximum output current

rating (see Table 3-1) exceeds the contact ratings of the relay.

This command is valid only if the power supply is configured for the optional relay connector. Programming ON closes the

relay contacts; programming OFF opens them. The relay is controlled independently of the output state. If the power

supply is supplying power to a load, that power will appear at the relay contacts during switching. If the power supply is not

configured for the relay option, sending eit her relay command generates an error.

Command Syntax OUTPut:RELay[:STATe] <bool>

Parameters 0 | 1 | OFF | ON

*RST Value 0

OUTP:REL:POL

Do not install or program the Agilent Relay Accessories if the power supply maximum output current

rating (see Table 3-1) exceeds the contact ratings of the relay.

This command is valid only if the power supply is configured for the optional relay connector. Programming NORMal

causes the relay output polarity to be the same as the power supply output. Programming REVerse causes the relay output

polarity to be opposite to that of the power supply output. If OUTP[:STAT] = ON when either relay command is sent, the

power supply output voltage is set to 0 during the time that the relays are changing polarity.

If the power supply is not configured for the relay option, sending either relay command generates an error.

Command Syntax OUTPut:RELay:POLarity <CRD>
