VOLTMETER:
Foran accurate reading of your battery'svoltage before you begin charging it, use the voltmeter as follows:
1.Set the timer to the OFF position, turn the voltage selector switch to 12 or 6 volt, according to the battery you are testing, and then connect the charger as indicated in the "Charging your battery in the vehicle" section on page 9. The charger does not have to be plugged into an outlet.
2.If a battery has recently been charged or in a vehicle that has recently been operated, you may want to turn your headlights on for a few minutes before you read the meter to avoid a false reading from a surface charge. Then turn off the lights, read the meter, and follow the convenient color coding.
