5 – Front Panel Operation

54

Setting the relay mode (Agilent 66319B/66319D with Option 521 only)

Action Display
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.
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.
2REL:MODE HH

Enable the output

Action Display
1. On the Function keypad, press Output On/Off to enable the output. The Dis
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.
8.003V 0.500A
3 - Setting the Output 2 Voltage and Current (Agilent 66319B/66319D 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
! 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 7.003V 0.004A
2. An alternate way to enter a value: On the Function keypad, press Voltage. On the Entry
keypad, press Enter Number, 7, Enter.
2 VOLT 7.000
3. To make minor changes to an existing value: On the Function keypad, press Volt age.
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.
2 VOLT 8.000

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
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 8.003V 0.400A
2. An alternate way to enter a value: On the Function keypad, press Current. On the Entry
keypad, press Enter Number, .4, Enter.
2 CURR 0.400
