Point the instrument toward any light source (headlight) and look into eyepiece (7). The battery charge is at

a point on the left-hand part of the scale where the dividing line between light and dark (shadow) crosses the

scale.

NOTE

A little experience will enable you to quickly obtain the best contrast between

light and dark portions 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 measuring surface was not sufficiently cleaned or dried.
