24V Start
Use the ATO oscilloscope to test the starting process of the diesel vehicle, the purpose is to test whether the
performance of the battery is maintained in the normal range, the operation process is the same as the 12V start.
The specific operation is shown in Figure 3-8:

3.1.7
Cranking Current
Use an ATO oscilloscope with a current probe to conduct a current test on the starting process of the car
(automobile or diesel car), observe whether the current waveform is normal, use a current clamp of 600A or
above, and connect the BNC of the current clamp to channel 2. On, turn on the switch of the current clamp and
clamp the current clamp to the positive or negative power line of the battery. You need to clamp the entire positive
or negative line. Pay attention to the positive and negative polarity (positive current flows from the positive
electrode of the battery to the negative electrode).
The specific operation is shown in Figure 3-9:
