HEADLAMP INTENSITY MEASUREMENT
M1542001000602
Using a photometer, and following its manufacture’s
instruction manual, measure the headlamp intensity
and check to be sure that the limit value is satisfied.
Limit: 30,000 cd or more
NOTE:
.
1. When measuring the intensity, maintain an
engine speed of 2,000 r/min, with the battery in
the charging condition.
2. There may be special local regulations pertaining
to headlamp intensity, be sure to make any
adjustments necessary to satisfy such regula-
tions.
3. If an illuminometer is used to make the measure-
ments, convert its values to photometer values by
using the following formula.
I = Er
2
Where:
I=intensity (cd)
E=illumination (Iux)
r=distance (m) from headlamps to illuminome-
ter
