1. With the charger unplugged from the AC outlet, connect the charger
to the battery following the instructions given in Sections 6 and 7.
2. Plug the charger AC power cord into the AC outlet.
3. If necessary, press the BATTERY TYPE button until the correct type
is indicated.
4. Read the voltage on the digital display or press the display mode
button to set the tester to BATTERY % to read the voltage as a percent
of charge.
Tester and Charger: When first turned on, the unit operates only as
a tester, not as a charger. To continue to use it only as a tester, avoid
pressing the CHARGE RATE button. Selecting a charge rate activates
the battery charger and deactivates the tester.
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
battery will be set for the 2A charge rate and 12V REGULAR battery type.
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 CHARGE RATE switch until all
charge rate LED’s are off.
Tester Status LED’s: When the unit is operating as a battery tester, the
status LED’s light under the following conditions:
The CHARGED (green) LED will light if a charged battery is tested. •
The CHARGING (yellow) LED does not light in the battery test mode. •
The CONNECTED (red) LED lights when a properly connected battery •
is detected.
When the tester display mode is set to VOLTAGE, the CHARGED and
•
CHARGING LED’s won’t light.
