ENTRY DESCRIPTION
ETIME 01:23:45 The ETIME field displays the total
accumulated elapsed time for the instrument
since it's initial manufacture. This value
cannot be changed or reset.
TEMP 37.342° The TEMP field is not a user selectable
parameter but rather a read-out of the internal
temperature in degree
s Celsius. It is provided
for informational purposes only.

SET mode
The default mode of operation is an immediate mode in which changes to output parameters made
with the knob or the entry keypad are immediately reflected at the output.
To change the output voltage:

4.3.3 Change Output Values in SET Mode
The SET mode of operation is a mode in which changes to output parameters made with the knob or
the entry keypad do not affect the output until the Enter key is pressed. The AC source is put in this
SET mode by pressing the Set key twice. A blinking cursor indicates SET mode is active.
