How to adjust the power supply voltage
The factory setting of the power supply voltage to the test board is set to 5V, and users do not need
to adjust it usually.
This adjustment should only be made if any adjustment is required between 4.00 V and 5.50 V.
The power supply voltage can be adjusted by inserting a + screwdriver into the supply voltage
adjustment hole on the side of the control box and turning the adjustment volume.
Check the voltages between ribbon cable connector pin numbers 1 to 6 (VC+) and 45 to 50
(GND).
