This section describes how to use the tester to perform tests on car batteries and charging
systems. The menu-driven display will guide you step by step through the test process.
3.1 Connecting The Tester
The tester powers on automatically when it is correctly connected to the battery. The preferred
test position is at the battery terminals. If the battery is not accessible, you may test at the jumper
post; however, the power measurement may be lower than the actual value.
To connect the tester:
1. Clean the battery posts or side terminals.
2. Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-)
terminal.
3. Rock the clamps back and forth to make sure the clamps are firmly connected. In case the
connection is poor, a “CHECK CONNECTION” message displays.
4. When the tester is correctly connected, it boots up automatically and show the voltage of the
battery.

5. Press the MENU button to go to the Main Menu.
NOTE
Do not connect the tester to a voltage source greater than 30VDC; otherwise you may damage
the tester.
NOTE
If you are testing inside a vehicle, make sure all accessory loads are cut off, the key is not in the
ON position and the doors are closed.
3.2 Battery Test
Battery Test menu lets you analyze the battery healthy status to calculate the actual cold
cranking capability of the battery and the aging status. It lets you check 12V or 24V charging
system to make sure the output voltage of the generator is normal, the rectifier diode works
correctly and the charging current is normal. Also it lets you checks if the starting motor works
correctly by testing its cranking current and cranking voltage.

Test Results
Interpretation
1
NO PROBLEMS
System is showing normal output from the alternator.
2
NO OUTPUT
No alternator output detected.
Check all connections to and from the alternator,
especially the connection to the battery. If the
connection is loose or heavily corroded, clean or
replace the cable and retest.
If the belts and connections are in good working
condition, replace the alternator. (Older vehicles use
external voltage regulators, which may require only
replacement of the voltage regulator.)

3
LOW OUTPUT
Alternator not providing sufficient to power the
system's electrical loads and charge the battery.
Check the belts to ensure the alternator is rotating
with the engine running. Replace broken or slipping
belts and retest.
Check the connections from the alternator to the
battery. If the connection is loose or heavily corroded,
clean or reparable the cable and retest.
4
HIGH OUTPUT
Alternator voltage output exceeds the normal limits.
Make sure there are no loose connections and the
ground connection is normal. If there are no
connection problems, replace the regulator. Most
alternators have a built-in regulator that requires
replacing the alternator. In older vehicles that use
external voltage regulators, you may need to replace
only the voltage regulator.
