Immediate Action Keys

Immediate action keys immediately execute their corresponding function when pressed. Other function keys have commands underneath them that are accessed when the key is pressed.

Output

On/Off

Shift

Prot Clr

Shift OCP

This key toggles the output of the dc source between the on and off states. It immediately executes its function as soon as you press it. When off, the dc source output is disabled and the Dis annunciator is on.

Press this key to reset the protection circuit and allow the unit to return to its last programmed state. The condition that caused the protection circuit to become active must be removed prior to pressing this key, or the unit will shut down again and display the Prot annunciator again. (If FS protection is displayed on the front panel, the unit must be opened and an internal fuse replaced as described in the Service manual.)

Press this key to toggle between OCP enabled and disabled. If OCP is enabled the output will become disabled if the output mode changes from CV to CC mode. The OCP annunciator indicates the state of OCP.

Scrolling Keys

Scrolling keys let you move through the commands in the presently selected function menu.

• ‚ Press q to bring up the next command in the list. Press p to go back to the previous command in the list. Function menus are circular; you can return to the starting position by continuously pressing either key. The following example shows the commands in the Input function menu:

q	CURR:RANGE <char>

q	CURR:DET <char>
