Question 1 of 1

Which of the following statements is NOT true regarding relative compression testing?

The test is a comparison of cylinders and does not indicate actual compression.

The test can only be performed with a high current amp clamp.

Ignition timing can be assessed by adding an ignition synch to the pattern, using a second scope channel.
Ignition synch is used to help identify which cylinder is causing each peak in the relative compression pattern.
