CHAPTER 4: MANUAL OPERATION
4.1 Manual Operation
1. Power On Condition
Every time when turning on the AC Power Source, the voltage and current displays will indicate
model and version respectively for the particular AC Power Source. After that the CPU will provide
a beep sound to show the pervious setting.
2. Setting of Output Voltage
During the RESET or TEST condition for the AC Power Source, the desire voltage can be set by
pressing “︿” or “﹀” key below the Voltage display. High range voltage can be set between
0-300V while low range voltage is 0-150V.Or high range voltage can be set between 0-600V while
low range voltage is 0-300V. Press and hold the “︿” or “﹀” key will firstly clear the decimal
number of setting to zero. Subsequently, every 0.3 seconds will change a step and thereafter a
first integer of setting number will vary and then to the second integer and third integer of the
voltage setting respectively. For the third integer, it takes 0.1 seconds only to vary every step in
order to speed up the scrolling. The voltage meter will flash and memorize the new setting then
exit automatically the setting mode if the setting is hold after 2 minutes.

Note. If the desired voltage is lower than low range, select high Range first. Otherwise the
output voltage only can be set to max value of the low range。
3. Setting of Output Frequency
During the RESET or TEST condition for the AC Power Source, the desire frequency can be set by
pressing “︿” or “﹀” key below the Frequency display. Each change on the setting are 0.1Hz/step
for normal setting and 1Hz/step for coarse setting. As the 50 Hz or 60 Hz key is being pressed, the
desired frequency will be immediately updated. (The same method applied like voltage setting to
scroll the display).
Note: Option 45.0-500.0Hz, for frequency setting in the range of 45-99.9 Hz, each change on
