weak or run down battery. Always use in combination with a battery.
Timer
Timer Setting • : The timer allows you to set a specified time for charging,
after the timer expires the charger stops charging your battery. The main
function of the timer is to prevent over charging 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. It is important that you determine the appropriate
state of charge of your battery as specified in Section 13 and set the timer
accordingly.
Hold
• : This position defeats the timer function, allowing for continuous
operation. Use it when you want to charge more than 2¼ hours. Be sure to
monitor the charging procedure and stop it when the battery is charged. Not
doing so may cause damage to your battery or may cause other personal
property damage or personal injury.
Ammeter
The Ammeter indicates the amount of current, measured in amps, that is being
drawn by the battery. As a battery takes on a charge, it draws less current from
the charger. Correspondingly the meter will show less current being drawn by
the battery. When the current stops decreasing, the battery is charged.
The start area of the meter indicates a high rate of current being drawn from
the charger. When cranking an engine, the meter needle will be at the extreme
right side of the start area.
The 2 amp charge rate may indicate some activity on the meter, although the
meter does not have the resolution to display this low rate.
