Numeric Keypad
Allows numbers and alphanumeric values to be
entered. When entering alphanumeric values,
pressing a key will display the first letter shown on the
key. Repeated key presses will toggle through all the
letters, both upper and lower case, shown on the
keycap. To enter two letters which appear on the
same keycap, select the first character, then use the
right arrow to shift to the next position and enter the
next letter. When data entry is complete the
ENTER
key must be pressed. The
FUNC
key allows a key to
select the secondary function/menu in yellow directly
above the key.
The second level menus (indicated in yellow above certain keys) are accessed
through the use of the yellow

key once and then
pressing the desired menu key will display the specified second level menu.
Pressing the

mode, where the second level menus can be accessed without repeatedly
pressing the

FUNC
key a third time will exit Function
Lock mode.

Each channel has two outputs on the front panel:
Channel Outputs (BNC Connectors)
1. Voltage Monitor
This is an analog representation in volts of the voltage
output to the load. The transfer function of this
follower is 0.2 V/V, as listed directly below the monitor
BNC connector.
2. Current Monitor
This is an analog representation in volts of the current
output to the load. The transfer function of this
follower is 0.5 V/A, as listed directly above the monitor
BNC connector.
The outputs of the voltage and current monitors are optically isolated and
have a typical 1us delay.
Each channel has four panel LED indicators and one button led indicator to
reflect the current status of the channel:
