Measurement Method

Measurement Method:

1. Clamp the SECONDARY PICKUP around spark Plug cable.

NOTE:
1. The peak of the ignition voltage will be reversed when the spark cables of 2 and No. 4 as well No. 1 and No. 3 cylinders are clamped.
2. Because of the two-cylinder simultaneous ignition system, the waves for two cylinder in each group appear during wave observation (No. 1 cylinder - No. 4 cylinder, No. 2 cylinder - No. 3 cylinder). However, wave observation is carried out for the cylinder with the spark plug cable clamped by the secondary pickup.

2. Clamp the spark plug cable with the Trigger pickup.

NOTE:
1. Clamp the spark plug cable for the No. 1 and No. 3 cylinder of the same group with the cylinder that is clamped with the secondary pickup.
2. Identification of which cylinder wave pattern is displayed can be difficult, but the wave pattern of the cylinder which is clamped with the secondary pickup will be stable, so this can be used as a reference for identification.
