1.
Turn on the Main Power SW.
Use the Digital multi-Meter that can measure the
direct voltage.
2.
Put the black probe into CN51-1pin (GND) and the
red probe into CN51-8pin (Vout) on the SW Power
Supply.
3.
Rotate the volume clockwise using the screwdriver to
adjust the output voltage value to +41V+0.1.
When the output voltage exceeds the +41.4V,
SW Power Supply does not output the voltage by
the protection circuit on it.
In this case, SW Power Supply will output the
voltage by rotating the volume counterclockwise.
When the protection circuit works, SW Power
Supply may not output for a while. Measure the
voltage some time later again.
