Ammeter: The ammeter indicates amount of current
measured in amperes that is drawn from battery.
When a battery is close to being dead or has a
very low charge, it will want to draw more current.
When a dead or low battery is charged, the charger's
ammeter will register at high end. As the battery charges,
the reading will move down toward the low end,
resting on zero, when battery is fully charged.
Do not depend on reading ammeter to approximate
how long charging will take. Even at full charge,
ammeter will still provide as much as 50% of charger's
output rating. Sometimes conditions such as a cold
battery, a sulfated battery, or a deeply discharged
Lead Calcium battery may cause ammeter to read near
a full charge when charging process is only beginning.

Note: The ammeter shows the amount of current
being drawn from the charger. It does not
show what the charger is capable of delivering.
When the battery is fully charged and registering
zero on the ammeter, a small charge will continue to
move from the charger to the battery. If the charger
is not disconnected from the battery, eventually
heat build up will cause the battery acid to boil and
overcharge the battery causing damage to the battery.
Monitor battery charging progress constantly and if
battery gets warm, stop charging it immediately.
Mode Switch: Use this to set the
voltage/amperage output.
