2.2 P/O State
The AC source allows the user to store the output settings as the default settings before pow-
ering the unit off.
If ‘
OFF ’ is selected the unit will NOT store any settings when powered off and initialize with
factory default at power on.
If ‘
LAST ’ is selected the unit will store the last setting in effect when powered off and recall
this same setting at power on.
If ‘
USER ’ is selected a user-defined setup can be assigned for recall when the power source
is turned on.
For example, to set ‘P/O State’ as ‘USER’, ‘Couple’ set as ‘AC+DC’, ‘Vac’ set as 100V, ‘F’ set
as 50 Hz, and ‘Vdc’ set as 20V.
1. In the ‘System Setting’ menu, press the ‘P/O State’ soft key and scroll to the User entry, then
press the [Enter] key to confirm.
2. Move the cursor to highlight ‘Couple =’ field, then press the [Enter] key to confirm.
3. Rotate the front panel knob to highlight the ‘AC+DC’ option, then press the [Enter] key to
confirm.
4. Use the [0]~[9] number keys as desired and [Enter] key to set ‘Vac’, ‘F’, and ‘Vdc’ settings.
