TESTER AND CHARGER
When first turned on, the unit operates only as a
tester, not as a charger. Pressing the Start/Stop
button or waiting 30 seconds from power-up
activates the battery charger and deactivates the
tester. Pressing the Start/Stop button again will
shut off the charger and activate the tester.
TESTING AFTER CHARGING
After the unit has been changed from tester
to charger, it remains a charger. To change
the battery charger back to a tester, press the
Start/Stop button.
POWER-UP AUTO START
The charger is equipped with an auto-start feature
which is triggered only when the charger is first
powered up. If the Start button is not pressed within
30 seconds, the unit will search for a battery. If the
unit detects a battery that is properly connected,
the unit will set the rate to 15 A and the battery
type will be set to AGM. The charging process will
automatically start, and the Charging (yellow) LED
will light.
