5. Fine Tuning the output Voltage (10 ~15 V)
This regulated power supply has been factory preset at a stable DC
output.
Rarely you need to do any fine tuning under normal operation.
However, should the need for specific precise output voltage other
than the preset voltage is required, refer to the following procedure.
1. Let the
power supply warm up for about 15 min.
2. Turn the power supply over with the bottom up and connect a
digital Multimeter (DMM) with at least 2 decimal read out to the
main output terminal (4).
3. Locate the fine tune access hole (8) on the bottom as shown in
Fig.1.
4. Insert a slim flat head screw driver to get to the trimmer as
shown in Fig.1.
5. Carefully and slowly turn the screw driver clockwise or anti-
clockwise while keeping an eye on the DMM for your desired
voltage setting.
