3.4.2 Calculation of corrected power
Multiply the measured brake power or torque by the
calculated diesel engine correction factor to obtain a
corrected value.
If the applicable range of the correction formula is
exceeded, indicate the corrected values and record the test
conditions on the test record.
Colculation output = Correction factor
