On the expiry of seven seconds after programming, the instrument returns automatically
to the operating mode. Refit the board cover.
Note: If no information on the type of the tyre fitted is available, it is allowed to measure
the value Rk as a distance from the wheel axis to the ground prior to beginning the oper-
ation of the tractor.
1.4. Connecting the tachospeedometer
To connect the tachospeedometer to the instrumentation system, a 9-contact block is
provided on the rear panel of the instrument (Fig. 3).
