DIGITAL DISPLAY
The Digital Display gives digital
indication of voltage, % of charge
or alternator status. It also gives
Cool Down time remaining during
Engine Start. When chosen by the
Display Button, the display will show
the battery voltage, % of charge
or alternator status under certain
conditions. First, when connected
to a battery but not charging, all
three options are available. When
charging begins, the display will
automatically change to the Voltage
option, show On to indicate charging
has started, and then either 6 or
12, the voltage type of the battery
determined by the charger. If the
battery voltage is low, the display
will continue to show On until the
voltage type is determined. % of
charge is an option only after the
voltage type, 6 or 12 is determined,
and also only for the Charge rate.
Alternator status is an option only
when not charging and for 12V
battery types. When the battery
is fully charged, indicated by the
Charged/Maintaining (green) LED
lit, the display and all other LEDs will
turn off to conserve energy during
Maintain mode.
DISPLAY BUTTON
Use this button to set the function
of the digital display to one of the
following:
• Battery % – The digital display
shows an estimated charge
percentage of the battery
connected to the charger’s battery
clamps.
• Alternator % (12V only, when
not charging) – The digital
display shows an estimated output
percentage of the vehicle’s charging
system connected to the charger’s
battery clamps, compared to a
properly functioning system. The
alternator percent range is from 0%
to 100%.Readings below 0% (13.2
volts) will read LO and readings
above 100% (14.6 volts) will read HI.
If you get a HI or LO reading, have
the electrical system checked by a
qualied technician.
• Voltage – The Digital Display
shows the voltage at the charger
battery clamps, in DC volts.
RATE SELECTION BUTTON
Use this button to select one of the
following:
• 6<>2A CHARGE/MAINTAIN – For
charging small and large batteries.
Not recommended for industrial
applications.
• 30<>12A BOOST – For quickly
adding energy to a severely
discharged or large capacity
battery prior to Engine Start.
• 80A ENGINE START – Provides
additional amps for cranking an
engine with a weak or run-down
battery. Always use in combination
with a battery.
NOTE: In general, pressing the
Rate Selection button advances
the selection to the next choice
and lights the corresponding
LED; charging will begin within
a few seconds of release of the
button. However, when charging
has begun, pressing this button
stops charging, which will cause
the display to temporarily display
OFF. The rate LED will turn off and
the Charging (yellow/orange) LED
will turn off. Then, the next button
press will go back to the same
rate selection that was turned off
and turn on its LED. Charging will
begin in a few seconds and the
Charging (yellow/orange) LED will
turn on. If the previous selection is
not wanted, continue pressing the
button to choose the preferred rate.
