ATOx004 manual - Page 59

The ATO oscilloscope can test the charging ripple and assist the user to determine whether the charging process is

normal. Use a BNC to banana cable, one end is connected to the oscilloscope channel 1, and the other end is

clamped between the positive and negative electrodes of the battery (the red wire is connected to the red clip)

Connect the positive pole, and connect the black wire to the black clip to the negative pole). Start the vehicle and

start the test. At this time, the oscilloscope is coupled to AC, and what is displayed is not the true voltage value. It is

based on the DC waveform and the difference relative to the DC voltage.
