Manual operation. Must be monitored.
TIMER: The main function of the timer is to prevent over charg- ing while allowing a battery time to obtain a satisfactory charge. To properly set the timer you must know the size of the battery in ampere hours or reserve capacity in minutes and the state of charge. Often the state of charge is not known, this is one rea- son why the timer was limited to 2.25 hours. With the aid of a battery load tester the state of charge can be obtained within a few seconds. For example, the average size automotive battery at a 50% state of charge will require 1 to 1.5 hours of charging at the 40 amp rate to reach the full charge state. For the same battery with the timer set to it’s maximum, 2.25 hours, over charg- ing will occur, but not likely cause harm to a battery that was other wise in good condition. When the charge state is not known, start out with a timer setting of 1 hour or less.
HOLD This position defeats the timer function, allowing for con- tinuous operation. Use when you want to charge more than 2.25 hours. This is normally the case when the 2 amp charge rate is selected. Be sure to monitor the charging and stop the charge when the battery is charged.
Rotary switch - Use the rotary switch to select the charge rate or engine start setting you require. Read the switch dial for those available on this charger.
The Ammeter indicates the amount of current measured in am- peres that is being drawn by the battery. For example, In the 40 amp charge rate a typical discharged battery will initially draw
approximately 40 amps. As the battery continues to charge, cur- rent will taper to 15 to 20 amps at full charge. The Start area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine, the starter motor draws up- wards to
The Voltmeter indicates the voltage at the battery terminals. Note that Model SE 2254 is not a Load tester, but a voltmeter. Use as follows:
1.Charger need not be plugged into AC outlet. Timer should be in the Off position, 6v/12v switch in position to match battery being tested, and then connect following instruc- tions in Section F.
2.Observe the meter indication. Keep in mind that this read- ing is only a battery voltage reading, a false surface charge may mislead you. We suggest that you turn on your headlamps for a couple of minutes before you read the meter. Read a couple of minutes after you have shut the headlamps off, then follow the convenient color code of the meter.
