4.4. Test low voltage (LV) source operability. Touch the black probe on the GND test point and the red
probe on the 5V test point. The voltage should measure between 4.8 and 5.2 Volts. If not, disconnect
power and check all relevant joints quality and polarity.
Do not continue with the assembly until the error will be corrected.
4.5. Once the last test of LV source is completed, disconnect the power.
