### 2.4.4 - Manual Measurement of "W" factor for KTCO

For the measurement of automatic "W" factor in a vehicle equipped with KTCO, just run the same
previous procedure from the step 1, by changing the cable for tests and the option in step 2 from
MTCO to KTCO.
For the measurement of the mechanical macrograph KTCO 1308 is necessary to attach the Adapter
Box (page 05/item 05) and use the sensor of 08 or 10 impulses/lap in the gearbox. In this case, the
number of laps/km will be equal to the number of measured pulses divided by the number of emitted
pulses by the sensor, i.e.:
Nº. laps/km = __Nº. measured pulses__
08 or 10 pulses/lap

Procedures
Select Manual Meas. W .
This function is the manual measurement of
W factor, using two points of reference
distant, at least, 20 meters between them. It
is essential the operator's in this method of
measurement.
Select MTCO
This function prepares the Calibrator to
capture the speed signal from the
sensor, including differentiating it in
amplitude and format.
At this moment drive the vehicle toward
the first point of reference and, passing
through it, press the F1 key to start the
F1
measurement.
By
reaching
reference, the operator must press the F2
key to finish the counting of pulses.
Enter the distance traveled between the
two points of reference.
In case of 20 meters, type 2 0 0 0, without
adding point or comma. The calibrator will
understand that this is 20 and not 2000
meters.
After entering the value of the distance
traveled and pressing the E key, the value
of the constant "K" being adjusted is
shown on the display.
