Tester Mode - Helvi Explorer 120 Manuel D'instructions

Step 1: Analysis
Analysis of the battery condition (charge level,
inversion, polarity, wrong battery connected, etc).
Step 2: Charging
Fast charging at maximum current until U1 is
reached
(ex: 13.8 V to )
Step 3: Absorption
Charge under constant voltage U1 (ex: 13.8 V in
). Maximum duration 1 hour.
• Abnormal undervoltage protection:
This protection prevents the risk linked to possible short circuits or battery being too damaged. The charger
will automatically stop if the voltage is abnormally low for more than 10 minutes.
General navigation :
1 Use the arrows to select the test to be performed
2 Press the START/STOP button to start the test
• Voltage test:
This mode allows you to view the voltage at the terminals of the charging clamps
and thus use your Explorer 120/130 as a voltmeter, in order to measure the
battery voltage.
• Start-up test:
The purpose of this mode is to evaluate the state of a vehicle starting system (starter + battery) when the
engine is turned on. This test must be done with the battery connected to the vehicle.
1 Use the arrows to select the nominal voltage of the vehicle
battery
2 Press the SELECT button to confirm
3 Connect the clamps to the vehicle battery
4 Start the engine by turning the ignition key
The charger automatically detects the engine start attempt and runs a cal-
5
culation algorithm to determine the state of the start system.
Test result: The charger indicates the minimum value of the battery voltage
perceived during the engine start phase, as well as the status of the start system
in the form of a gauge.
• Alternator test :
This mode is used to determine the condition of the alternator in the vehicle. This test is performed on a
vehicle with the engine running.
1 Use the arrows to select the nominal voltage of the vehicle
battery
2 Press the SELECT button to confirm
Test result: The charger indicates the voltage provided by the vehicle alternator,
as well the alternator status in the form of a gauge.
Step 4: Complement
Gradual increase of the voltage up to U2
(ex: 14.4 V to
Step 5: Equalization / Balancing
Maintaining the voltage U2 (ex: 14.4V at
Maximum duration 2 hours.
