Grading Method - SmartWitness KP1S User Manual

Excess RPM Duration Ratio
This option sets the grading criteria for excessive RPM over the RPM limit set. This
value is estimated as a percentage of the amount of time driving. For example, if a
driver drove 8 hours in a day but was exceeding the RPM limit for 1 hour, their score
for this criteria would be 12.5% and based on the image on page 43, they would be
graded as A.
The assessment of this criteria is based on the RPM limit option in the 'Analysis
Criteria Setting'. This criteria is used for eco grading only.
Idling Count
This option sets the grading criteria for idling and is calculated per hour. For
example, if a driver drove 8 hours in a day but exceeding the idle time limit 4 times,
their score for this criteria would be 0.5 and based on the image on page 43, they
would be graded as B.
The assessment of this criteria is based on the RPM limit option in the
'Analysis Criteria Setting'. This criteria is used for eco grading only.
PLEASE NOTE
Once the grading criteria settings has been adjusted and saved, it can be exported
into an '.ini' file and then imported into another version of the analysis software.
This means that you can set each KP1S quicker than manually adjusting the settings
in each version of the software.

Grading Method

Grades: Each criteria is given a grade of A, B, C or D and anything lower is given a
grade of F for fail. Therefore each grade will be assigned a limit that if exceed, the
score will go down to the next grade. If the driver exceeds the limit for the D grade,
they will be given an F.
Weights: Each criteria can be given a different weight when calculating the safety
and eco grades to provide flexibility to the operator in assessment.
