USER MANUAL DBT 300 Toolit

This manual includes guidelines on the operation of your device and the precautions to follow for your own safety.

Ensure it is read carefully before first use and keep it handy for future reference.

Risk of explosion and fire!

A battery being charged can emit explosive gas.

The battery tester should only be connected to batteries with a rated output voltage of 12V .

CAUTION: Reverse polarity will cause the fuse to blow and could cause permanent damage. Damage due to reverse polarity is not covered by our warranty.

CAUTION: If the car's battery is disconnected, some management systems may be disabled.

Consult your vehicle manual for more information on installation.

Do not use the battery tester if the cord or terminals are damaged.

Do not use the battery tester if it has received a severe shock or has been damaged in any way.

Do not disassemble the device. Incorrect reassembly may result in a risk of electric shock or fire.

Acid projection hazard!

• Wear appropriate safety glasses and clothing.
• If your eyes or skin come into contact with battery acid, rinse the affected part of the body with plenty of water and seek immediate medical assistance.
• Avoid flames and sparks. Do not smoke.
• Protect the electrical contacts of the battery against short-circuiting.

The device complies with European Directive.

The certificate of compliance is available on our website.

EAC conformity mark (Eurasian Economic Commission)

Recyclable product that falls within waste sorting recommendations

CONNECTING THE BATTERY TESTER

1- Make sure that the area is well ventilated before performing a test.
2- Tester for 12 V batteries (and START & STOP 12 V batteries) and test of the charging system.
3- Before performing a test on the battery, make sure that the ignition and the consumers are switched off. Close all doors and the boot.
4- Make sure that the battery connections are clean. If necessary, clean them with a wire brush.

The presence of oxydation between the tester terminals and the battery connectors or between the connectors of the battery and the terminals decreases the tester efficiency.

5- Connect the negative (black) terminal to the negative terminal of the battery. Connect the positive terminal (red) to the terminal positive of the battery.

BATTERY VOLTAGE

1. Once the tester is connected, the display shows the battery voltage. Press and select «BAT» to start the battery test. Confirm by pressing
2. Select the battery type (Liquid / AGMS / GEL / AGMF) using the arrows . If it is a «START/STOP» Battery, select between «SSA» or «SSEFB» (SS means start & stop). Press to validate and access the other criteria.
3. Choose the standard written on the battery and validate (possible standards: CCA, BCI, CA, MCA, DIN, IEC, EN, SAE, GB)
4. Enter the starting current, indicated on the battery, using the arrows (ex : 830SAE) then validate.
   The test starts. If the tester displays BAT, & XX.XX V, charge the battery and test it again. If the display remains the same, replace the battery.
   If the tester displays «BAT. CHARGED» (Is the tested battery charged?), press and select, «YES» or «NO».

Battery test result

Result Analysis
OK The battery is operational.
OK RECHARGE Battery in good condition but low state of charge.
RECHARGE RETEST Charge the battery and perform the test again.
BAD	The battery is nearing the end of its life. Replacement required. OR a problem at the cell level is observed (short circuit....). Replace the battery.
ERROR CHARGE	Battery exceeds 1200 CCA (SAE) or clamps are not properly connected. If neither of the two causes listed above is involved, fully recharge the battery and test again. If the display remains the same, replace the battery.

1. In each case, to display the battery health status (SOH) and charge status (SOC), press to scroll through the results.

1. If the starting voltage is normal, press to continue the test. The display shows ALT. & XX.XX V>

2. Run the engine between 1200 and 1500 rpm.

3. One of the 3 results is displayed:

Result of the start voltage test

Examples Results displayed Analysis
High starting voltage when the test is performed with the engine at idle	HI (= High)	Check that the connections are good. If every-thing is properly connected, replace the alterna-tor.
Normal starting voltage when the test is performed with the engine at idle	OK	No problem detected. Normal operation of the alternator.
Low starting voltage when the test is performed with the engine at idle	LO (= LOW)	The alternator does not provide enough power to the battery. Check the alternator belts, and make sure the alternator is running when the engine is running. If the belts slip or are broken, replace them and re-test. Check the connection between the alternator and the battery. If the connection is bad, clean or replace the cable and re-test. If the alternator belts and connection are in good condition, replace the alternator.

- Result of the load system test with consumables running

1. Turn on the heater to maximum (heat), headlights and taillights. Do not switch on cyclic loads such as air conditioning or windshield wipers.

Examples Results displayed Analysis
High starting voltage whenthe test is performed with the consumers running	HI (= High)	"The output voltage of the alternator is abnormally high. Check that there are no connection problems. If not, replace the alternator."
"Normal starting voltage when the test is performed with the consumers running"	OK	No problem detected. Normal operation of the alternator.
"Low starting voltage when the test is performed with the consumers running"	LO (= LOW)	The alternator does not provide enough current for charging the electrical system and the battery. Check the alternator belts, and make sure the alternator is running when the engine is running. If the timing belts slip or are broken, replace the timing belts and re-test. Check the connection between the alternator and the battery. If the connection is bad, clean or replace the cable and re-test. If the belts and connection are in good condition, replace the alternator.

1. Press to display the ripple intensity of the charging circuit. The display shows RIPPLE & XX.XX V

Results found Screen display		Analysis
Normal wave intensity OK		The diodes work well in the alternator/starter
High wave intensity HI		"One or more diodes do not do not work or are damaged. Make sure that the alternator support is properly positioned and that the belts are working properly. If so, replace the alternator."

DISPLAY SCREEN CASE

Examples Analysis
