2.4 – Description of functions
Then each function will be detailed in sequential order, for the two lines of tachograph, because the
operations are the same. The content of the display, for each case, will also be presented along the
sequence that must be carried out by the keypad.

2.4.2 - Automatic 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 tachograph 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
Select Auto Measurement W.
This function is the automatic measurement
of W factor, using two optical sensors
(optional). In this case they must be
positioned at 20 meters of each other and the
issuer must be fixed to the vehicle.
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 optical sensor and continue
toward the second that must be distant
20m from the first one.
By going to the first sensor, will start up
automatically the counting of pulses,
ending up only with the passage through
the second sensor.
After the passage through the second
adjusted to the constant "K" is shown on
