(5) Point the instrument toward any light
source (headlight) and look into eyepiece
(6). The battery charge is at a point on the
left part of the scale where the dividing line
between light and dark (shadow) crosses
the scale.
The illustration shows a reading of 1.120
specific gravity points, which indicates that
the battery requires recharging.
NOTE
A little experience will enable you
to quickly obtain the best con-
trast between light and dark por-
tions of the field of view. Tilt the
instrument toward the light
source until the best results are
obtained. If the edge of the
shadow is not sharp, the measur-
ing surface was not sufficiently
cleaned or dried.
d. Inspect battery cables for frays, splits, and
looseness.
