Arrival AUTOOL BT660 Battery Analyzer BT-660 Car Battery Tester Supports Printing Data Out

Product specification:
1. Application: 12V automotive cranking lead acid battery and 12v/24v car system test
2. Measure Range:

4.Working Environment Temp:-12℃-50℃
5.Special test clip: Double conductance Kelvin clamp
6.Housing Material: Acid-resistant ABS plastic

1.Connect the red test clamp with battery anode and the black one with cathode, the tester will power on automatically. Voltage battery below 7.0VDC can't be tested properly, then press OK key to continue.
2.According to the tester, you can press UP/DOWN key to choose:
① Battery Test
② Cranking Test
③ Charging Test
④ Review Data
⑤ Print Data
⑥ Export Data to Computer

1. Charging Volt: Normal. The generator output normal, no problem detected.

2. Charging Volt: Low. Check drive belt of the generator whether slip or running off.Check the connection between generator and battery is normal or not. If both of the drive belt and the connection are in good condition, follow the manufacturer's suggestion to eliminate generator fault.

3. Charging Volt: Hight. Since most of the vehicle generators are using internal regulator, the generator assembly has to be replaced.(Some old style cars are using external regulator, then directly replace the regulator.) The normal high volt of the voltage regulator is maximum 14.7±0.5V. If charging volt is too high, it will overcharge the battery. Therefore, the battery life will be shortened and troubles will be caused.

4. No Volt Output. No generator volt output is detected. Check the generator connection cable, the drive belt of generator and engine whether normal or not.

5. Diode Test: Through the test of charging current ripple, tester will find out whether the diode is normal or not. When ripple volt is too high, it proves at least one diode is damaged. Check and replace the diode.
