Combination Tests
The electronic faults of automobiles are sometimes more complicated. We need to use an ATO oscilloscope to
perform combination testing, compare several waveforms that collected, and help users judge the fault by observing
and analyzing the timing relationship and quantitative relationship between the waveforms. , The ATO is a powerful
tool to solve such complex problems.
3.6.1 Cran Camshaft
Use a BNC to banana cable, one end is connected to channel 1 of the oscilloscope, the other end is grounded with
a black plug, and the red connector is pierced into the signal line of the crankshaft sensor with a needle; use a
BNC to banana cable, one end is connected to channel 2 of the oscilloscope, and the other black end is grounded,
the red connector is pierced into the signal line of the camshaft sensor with a needle probe.
Use ATO oscilloscope to perform combined test on cran camshaft, the specific operation is shown in
