ENGINE STARTING NOTES
During the starting sequence, the charger
is set to one of three states:
• Wait for cranking – The charger waits
until the engine is actually being cranked
before delivering the amps for engine
start and will reset if the engine is not
cranked within 15 minutes. (If the charger
resets, it sets itself to the default start up
settings). While waiting for cranking, the
digital display shows the battery charged
percentage (it cannot be set to voltage).
After 5 seconds, the display will change
to ENGINE START READY.
• Cranking – When cranking is detected,
the charger will automatically deliver up
to its maximum output as required by
the starting system for up to 5 seconds
or until the engine cranking stops. The
digital display shows a countdown of the
remaining crank time.
• Cool Down – After cranking, the charger
enters a mandatory 3 minute (180 second)
cool down state. The digital display will
show ENGINE START COOL DOWN XXX
SECONDS REMAINING. It starts at 180
and counts down to 0. After 3 minutes,
the digital display will change to ENGINE
START READY. The
LED will then be lit.
USING THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in previous sections.
2. Plug the charger's AC power cord into
the AC outlet.
3. Set the ON/OFF switch to
Boost/Charge/Maintain. DO NOT
choose a rate with the Rate Selection
button.
4. If necessary, press the
button until the correct type is indicated.
5. Read the voltage on the digital display.
Keep in mind that this reading is only a
battery voltage reading; a false surface
charge may mislead you. Compare the
reading to the following chart.

TESTER AND CHARGER
When first turned on, the unit operates only
as a tester, not as a charger. Selecting a
charge rate activates the battery charger
and deactivates the tester. Pressing the
Rate Selection button when the
Engine Start LED is lit (except during
the 180 second cool down) will shut off the
charger and activate the tester.
POWER-UP IDLE TIME LIMIT
If no button is pressed within 10 minutes
after the battery charger is first powered
up, the charger will automatically switch
from tester to charger if a battery is
connected. In that case, the charger will be
set to charge at the 6<>2A charge rate and
Gel battery type.
TESTER WITHOUT TIME LIMIT
If either the
Battery Type button is pressed within the
first 10 minutes after the battery charger
is powered up, the unit will remain a
tester (not a charger) indefinitely, unless a
charge rate is selected.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a charge
rate), it remains a charger. To change the
battery charger back to a tester, press the
Rate Selection button until all charge
rate LEDs are off.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
USING THE ALTERNATOR
PERFORMANCE TESTER
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in previous sections.
2. Plug the charger AC power cord into
the AC outlet.
3. Set the ON/OFF switch to
Boost/Charge/Maintain. DO NOT
choose a rate with the Rate Selection
button.
4. Start the vehicle, rev the engine at
2000 rpm for 30 seconds and turn
on the vehicle's headlights or other
accessories.
5. Read the voltage on the digital display.
If you get a reading between 13.4
volts and 14.6 volts, the alternator
is working properly. If the reading
is less than 13.4 volts or more than
14.6 volts, have the charging system
checked by a qualified technician.
