Current Clamp

To test cranking amps and charging current, first connect the current clamp before tester startup, then turn on the current clamp power switch.
After tester connected, current clamp is able to work.
Press the reset key of the current clamp and connect the current clamp jaw to the anode wiring between the battery to be tested and the generator.
As the minimum width of the current clamp jaw is only 28mm, choose the connection cable or connection pole with diameter less than 28mm to test. Otherwise, the current clamp jaw cannot close completely.

warning NOTE:

Current clamp jaw must close to avoid test tolerance.
Current clamp uses 9V alkaline battery. Turn the clamp power off after using the current clamp.
Before testing the current, take off the current clamp from the battery positive connection cable, and reset.

Operations

This section describes how to use the tester to perform tests on car batteries and 12V&24V starting and charging system. The menu-driven display will guide you step by step through the test process.

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:

Clean the battery posts or side terminals.
Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal.
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.
When the tester is correctly connected, it boots up automatically and show the voltage of the battery
Press the MENU button to go to the Main Menu.

warning NOTE
Do not connect the tester to a voltage source greater than 30V DC; otherwise you may damage the tester.

warning 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.

Battery Test

Battery Test is mainly targeted to analyze the battery healthy status to calculate the actual cold cranking capability of the battery and the aging extent, which provide reliable analysis evidence for the test and maintenance of the battery. It notifies the user to replace battery in advance when the battery is getting aged.

To start a battery test:

Scroll with the UP or DOWN button to highlight Battery Test from Main Menu and press the ENTER key.
Scroll with the UP or DOWN button to highlight the voltage from Main Menu and press the ENTER key.
Scroll with the UP or DOWN button to highlight the TEST TYPE from Main Menu and press the ENTER key.
Scroll with the UP or DOWN button to highlight OUT OF VEHICLE or IN VEHICLE from BATTERY LOCATION menu and press ENTER to select the battery location.
Scroll with the UP or DOWN button to highlight TOP POST or SIDE POST from POST TYPE menu and press ENTER to select the battery post type.
Scroll with the UP or DOWN button to select the battery type from BATTERY TYPE menu and press ENTER to confirm.
Scroll with the UP or DOWN button to select the battery standard from BATTERY STANDARD menu and press ENTER to confirm. Not all rating systems are available for each application.

You may find the battery type and battery rating label on every battery.

Use UP or DOWN button to change measure range till you enter the correct range of your battery. Press ENTER to start the test.

If your battery belongs to CCA system, just select the right CCA number and press ENTER to start the test.
View test results on the screen. Depending on battery status, one of the following test results may display.

No.	Test Results	Interpretation
1	GOOD BATTERY	The battery is in good condition.
2	GOOD-RECHARGE	The battery is in good condition but low current. Fully charge the battery and return it to service.
3	CHARGE & RETEST	Fully charge the battery and retest. Failure to fully charge the battery before testing may result in inaccurate results. If you still get CHARGE & RETEST message after you fully charge the battery, replace it.
4	REPLACE BATTERY	The battery is almost dead or the connection between the battery and battery cable is poor. Replace the battery and retest; or disconnect the battery cables and retest the battery using the out-of-vehicle test before replacing it.
5	BAD CELL-REPLACE	The battery may be damaged such as broken cell or short circuit. Replace the battery and retest.

Use UP or DOWN button to check the second page of battery test result which include state of health (SOH), state of charge (SOC), and resistance (RES).
Press the BACK button to return to Main Menu. Or, press the ENTER button for cranking test if you are processing an in-vehicle test.

warning NOTE
The tester keeps the results of last test only. When you start a new test, the last results are overwritten.

Cranking Test

warning NOTE
Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the rpm levels needed for the test.

After an in-car battery test, the display alternates between the battery test results and the message PRESS FOR CRANKING TEST.

To start cranking test:

Press the ENTER button for cranking test.
Start the engine when prompted.
The tester displays the decision on the starter system, cranking voltage, and cranking time in seconds. For instance, as below display, the starter system is REPLACE BATTERT, cranking voltage is 10.76 V, and cranking time in second is 0.86 S.

No.	Test Results	Interpretation
1	CRANKING NORMAL	The starter voltage is normal and the battery is fully charged.
2	LOW VOLTAGE	The starter voltage is low and the battery is fully charged.
3	CHARGE BATTERY	The starter voltage is low and the battery is discharged. Fully charge the battery and repeat the starter system test.
4	REPLACE BATTERY	Battery must be replaced before the starting system can be tested.
5	NO START	No vehicle start detected.
6	CRANKING SKIPPED	A start was not detected.

Press ENTER button to proceed with the charging system test, Print button to print the test results, BACK button to return to the main menu.

warning NOTE
For an in-vehicle test, the display alternates between the test results and the message. Press ENTER for charging test.

Charging System test

Once you have completed an in-vehicle test, the display alternates between the battery test results and the message press ENTER for charging test. Press ENTER to proceed with the charging test.

To start charging system test:

Follow the on-screen prompts to Rev the engine.
Turn on high beams headlights and the blower fan.
Rev engine with loads on.
Idle engine and turn off loads.
The Charging System decision is displayed at the end of the procedure.

Charging System test - Step 1

No.	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.
5	EXCESSIVE RIPPLE	Excessive AC ripple detected. One or more diodes in the alternator are not functioning or there is stator damage.

Use UP or DOWN button to check the RIPPLE.
Press ENTER to print the test results or BACK to return to the main menu.
