1.Use Output ON/OFF to make sure that the output of the selected channel is off. The output must be turned off before any relay settings take effect. If the Dis annunciator is lit, the output is off.

2.Press Meter to return the display to Meter mode.

3.	Press Shift Channel to select either output channel 1 or output channel 2.	13.6V	2.04A
		27.5V	1.04A
4.	On the Function keypad, press OUTPUT. Then scroll to the REL:MODE command.	2REL:MODE HH

Use the ⊃ key to select one of the relay modes (DD, DH, HD, or HH) then press Enter. The Output ON mode is specified first, followed by the Output OFF mode. Relay settings cannot be coupled; they must be set separately for each output.

1.	On the Function keypad, press Output On/Off to enable the output. The Dis	8.003V 0.500A

annunciator will go off, indicating that the voltage is now applied to the output terminals. The A display indicates the actual output current. Note that when the outputs are coupled, this command also enables or disables output 2.

3 - Setting the Output 2 Voltage and Current (Agilent 66309B/D only)

This example shows you how to set the voltage and current for output 2. Selecting an output was discussed in the previous example. Note that no front panel changes affect the output of the unit unless it has been enabled.

Set the output 2 voltage

	Action	Display
1.	Press Meter, then Shift, Channel to select output 2. On the Entry keypad, press ∅ or	2	7.003V 0.004A
	∩ to select the 1’s digit in the voltage field. Then rotate the front panel RPG knob to
	obtain 7 V.
	If the unit is in CC mode, you won’t see the output voltage change until the voltage
	setting is low enough to cause the unit to go into CV mode.
2.	An alternate way to enter a value: On the Function keypad, press Voltage. On the Entry	2	VOLT 7.000
	keypad, press Enter Number, 7, Enter.
3.	To make minor changes to an existing value: On the Function keypad, press Voltage.	2	VOLT 8.000
	On the Entry keypad, press ∅ or ∩ to select the digit in the numeric field that you wish

to change. For example, move the flashing digit to the ones column to change a value in this column. Then, press ∪ on the Entry keypad to scroll from 7.000 to 8.000. Then press Enter.

Set the output 2 current limit

	Action	Display
1.	Select output 2 as described in example 1. On the Entry keypad, press ∅ or ∩ to select	2	8.003V 0.400A
	the tenths digit in the current field. Rotate the front panel RPG knob to obtain 0.4A.
	If the unit is in CV mode, you will not see the output current change until the current
	setting is low enough to cause the unit to go into CC mode.
2.	An alternate way to enter a value: On the Function keypad, press Current. On the Entry	2	CURR 0.400
	keypad, press Enter Number, .4, Enter.
