This allows you to see if one or two cells are discharging faster than the others. This is a fairly good test to see if a cell has lost capacity. A test cannot be made properly unless each battery cell has enough fluid to allow the float to rise freely. You will not get an accurate reading if water has been just recently added to the cells. Application TO PREPARE INSTRUMENT FOR USE AUTO TESTER • Remove instrument carefully from card. • Grasp hexagonal side of rubber tip at base of instrument and remove it from glass barrel. • Remove float from glass barrel by slowly pulling longer end of protective styrofoam strip. • Wet inside of glass barrel and re-insert rubber tip. • Now the battery tester is ready for use.
