If a chassis dynamometer is available, carry out test
as specified in para A, otherwise conduct test according to para B.
A Test on chassis dynamometer
1 Rev up vehicle to top speed of a gear.
2 Apply load to dynamometer and read off charge pressure at tester.
BTest without dynamometer
1 Load up vehicle to permissible payload.
2 Conduct simulated road test with different load states (accelerating on hill or sensitive operation of parking brake) and read off charge pressure on HHT.
