7. Speedometer
(1 km/h = 0.6214 MPH)
When the actual traveling speed of the vehicle is V
2
,
the reading of the speedometer (V
1
) shall meet the
following formula:
0 V
1
-V
2
V
2
/ 10 + 6
Ex. Case of a vehicle of [45 km/h
<
Vmax
55 km/h]
V
1
= 40 km/h
When the speedometer reading is 40 km/h, the
tester speed V
2
shall be as follows:
30.91 km/h V
