(b) Swing the plastic cover down until it rests against the
measuring window. Using the black dipstick, place a few drops of electrolyte
onto the exposed portion of the measuring window (Figure 26).

(c) Point the tester toward a bright light source. When looking
through the eyepiece lens, you will see a rectangle with two calibrated scales.
The battery charge readings will appear on the left scale; antifreeze readings
on the right scale. The electrolyte sample will divide the rectangle with an
area of light and an area of shadow. Read the scale where they meet (Figure 2

(d) Always perform a separate test for each battery cell. Test
the battery before adding water to the cells.
