Maintenance And Care - Schumacher Electric FR01234 Manual Del Usuario

POWER-UP IDLE TIME LIMIT
If no button is pressed within 15 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 the start-up default settings.
TESTER WITHOUT TIME LIMIT
If either the DISPLAY MODE or 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
BATTERY SIZE button until all BATTERY
SIZE LEDs are off.
BATTERY TESTER STATUS LEDS
When the unit is operating as a battery
tester, the status LEDs light under the
following conditions:
• The CHARGED LED will light if a
charged battery is tested.
• The CHARGING LED does not light in
the Battery Test Mode.
• The CONNECTED LED will light if a
properly connected battery is detected.
• When the tester's digital display is set to
voltage, the CHARGED and CHARGING
LEDs will not light.
INITIAL PERCENT CALCULATION
When BATTERY % is calculated for the
first time after connecting a battery, the
digital display will show three dashes
(---) for a few seconds, while the tester
analyzes the battery.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.

12. MAINTENANCE AND CARE

A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery
fluid that may have come in contact with
the clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the
finish shiny and help prevent corrosion.
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. Start the vehicle, rev the engine at
2000 rpm for 30 seconds and turn
on the vehicle's headlights or other
accessories. Read the voltage on the
digital display or press the DISPLAY
MODE button to set the tester to
ALTERNATOR % to read the voltage
as a percent of charge. Compare the
voltage reading to the following chart.
12V Alternator

14.6 or higher
13.5 to 14.5
Below 13.4
ALTERNATOR TESTER STATUS LEDS
When the unit is operating as an
alternator tester, the status LEDs light
under the following conditions:
• The CHARGED LED will light if the
output of the charging system is at the
normally desired level.
• The CHARGING LED does not light in
the alternator test mode.
• The CONNECTED LED lights if the
tester detects a connection.
• When the tester's digital display is set to
voltage, the CHARGED and CHARGING
LEDs will not light.
ALTERNATOR TESTING NOTES
• The alternator percent display can range
from zero to 199.
• The digital display cannot be set to
Alternator % during charging.
• An Alternator % of zero does not indicate an
Alternator output of zero volts; it indicates an
output too low to charge the battery.
• An Alternator % of 199 does not indicate
an Alternator Voltage nearly twice the
voltage of a normal alternator.
• Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
• Store the charger unplugged from the AC
power outlet, in an upright position.
• Store inside, in a cool, dry place. Do
not store the clamps clipped together,
clipped to the handle, on or around
metal, or clipped to the cables.
