5.4.1 Conditions for measurements at full load

Always follow safety precautions
Read measured value block
Note
Due to the various use cases of industrial engines, check
whether the engine attains full load under the respective operat-
ing conditions before performing measurements at full load.
– At full load, increase engine speed from 1500 rpm to full
throttle (accelerator pedal position sender at end stop).
– Have a second person read the measured values at approx.
3000 rpm.
– Exit diagnosis function.
– Switch off ignition.
