VR2400 MAIN MENU
:ROLLING ROAD
Increase the speed of the vehicle as indicated
by the rolling road equipment until it is steady
at 50km/h.
Hold at 50km/h
ENTER to Start
Press ENTER and the Programmer will start
counting pulses. The pulses will be audible as
low-pitched clicks.
Hold at 50 km/h
Reading pulses
After about 15 seconds it will emit an audible
beep and the measured W-factor will be
displayed. If appropriate for the selected
tachograph type the measured K-factor and
the required DIL switch setting will be
displayed. For Stoneridge VR2400/SE5000,
Kienzle 1319/DTCO, MotoMeter EGK-100 and
Actia Smartach tachographs the required W-
factor will be retained in the Programmer (until
the Programmer is turned off) ready for later
programming of the tachograph, as described
in Chapter 5.
W=8000 K=8000
DIL=_23_____9_
Note: In the case of the message ERROR!
CHECK CONNECTIONS being displayed,
ensure that the ground connection is made
correctly. Otherwise check the other
connections.

4.2.2 Fixed Distance Method No. 1
This method typically uses the 20m measured distance often available at tachograph fitting
stations, but it is possible to set to any distance from 20 to 1000m as required. The Fixed
Distance Length can be adjusted via the Diagnostics Menu (see Section 2.6).
Care must be taken to ensure that the Fixed Distance Length set and the actual track length are
the same, otherwise the W-Factor determined will be incorrect.
The vehicle is driven along the measured track and measurements made at either end of the track
are fed into the Programmer, from which the W-factor is determined.
