1) If pressure is below 294 kPa (3.0 kgf/cm2, 43 psi) at one or two chambers of a rotor, the tester indicates one correct measurement and two
00.0 readings.
2) If pressure is below 294 kPa (3.0 kgf/cm2, 43 psi) at three chambers, the tester indicates three 00.0 readings.
3) In the above cases, the cranking speed readings are all 00.0.
9. Check the rear chambers by using the same procedure.
10. Compensate the compression values if they are measured at cranking speeds other than standard or if they are measured at high altitude.
Cranking speed compensation
Compensate the compression according to the cranking speed.
Altitude compensation
Compensate the compression according to the altitude.
