5 - Programming the Output Relay (option 760 only)

Units with option 760 have isolation and polarity reversal relays connected to the output and sense terminals. (Option 760 is not available on HP 6631B units.)

To control the relays independently of the Output On/Off switch, proceed as follows:

	Action	Display
1.	On the Function keypad, press Output, and scroll through the Output	RELAY ON
	menu until you get to the RELAY command. The display indicates
	whether the relay is presently closed (ON), or open (OFF).
2.	Use the ã and ä keys to select either ON to close the relay or OFF to	RELAY OFF
	open the relay. Note that the output relays always open or close
	whenever the Output On/Off key is pressed.

To control the polarity of the output relays, proceed as follows:

	Action	Display
1.	On the Function keypad, press Output, and scroll through the Output	REL:POL NORM
	menu until you get to the REL:POL command. The display indicates the
	present condition of the relay (either normal or reversed).
2.	Use the ã and ä keys to select either NORM or REV. NORMal causes	RELAY OFF
	the relay polarity to be the same as the dc source output REVerse causes
	the relay polarity to be opposite to that of the dc source output.

6 - Setting the HP-IB Address and RS-232 Parameters

Your dc source is shipped with the HP-IB address set to 5 This address can only be changed from the front panel using the Address menu located under the Address key. This menu is also used to select the RS-232 interface and specify RS-232 parameters such baud rate and parity.

Set the HP-IB address as follows:

	Action	Display
1.	On the System keypad, press Address.	ADDRESS 5
2.	Enter the new address. For example, Press 7, Enter.	ADDRESS 7

Configure the RS-232 interface as follows:

	Action	Display
1.	On the System keypad, press Address.	ADDRESS 5
2.	Scroll through the Address menu by pressing q . The interface	INTF RS232
	command lets you select the RS-232 interface. The baudrate command	BAUDRATE 9600
	lets you select the baudrate. The parity command lets you select the	PARITY EVEN
	parity. The flow command selects the flow control options.	XON-XOFF
3.	The ã and ä keys let you select the command parameters.
