Feature 1Conductivity technology, which is simple and fast, without waiting, and the test results are accurate. 2Support car battery testing, and with car charging test system, car start testing system. 3Equipped with USB interface, it can be connected to a computer to print test results directly, which is highly practical. 4Widely used in 12V automotive cranking acid battery and 12V car system test. 5Easy to use and quick to install, and will not take up much of your time, very convenient.Item Type: Car Battery TesterHousing Material: Acid-resistant ABS plasticMICRO-200 Car Battery Conductance Tester: Product Specification: 1. Application: 12V automotive cranking acid battery and 12v car system test2. Measure Range: 30-200AH3. Working Environment Temp: -20-504. Special Test Clip: Double conductor for Kelvin clamp5. Measure Range: 30AH-200AH6. Voltage Measure Range: 7-16V DCHow to Use: 1.Connect the red test clamp with battery positive and the black one with negative, the tester will power on automatically.Voltage battery below 7.0VDC canrsquot be tested properly, then press OK key to continue.2.According To The Tester, You Can Press UP/DOWN Key To Choose: battery teststarting system testcharging system testbattery test resultprint test resultSelect languagePerform Battery Test: Select the battery test and press OK key to continue.Input Testing Standard: The standard which you can see the front of the battery, such as CCA, BCI, DIN. If you canrsquot find any info about the standard,you can choose GB standard. Choose GB standards for little tolerance.Input Rated Capacity: You can see the starting current standards in front of the battery. Such as BCI/300A.Then press OK key to start testing.Starting System Test: After Entering The Second Start System Test Functionthe Press OK Key as follows: Starting the engine as prompted, the tester will automatically complete the cranking test and display the result.Normally, cranking voltage value lower than 9.6V is regarded as abnormal and it is OK if it is higher than 9.6V.Test result of the tester includes actual cranking voltage and actual cranking time.When the cranking test is abnormal, battery test result will also be displayed at the same time.This is for the convenience of the maintenance personnel to quickly know the whole state of the starting system according to the data.Charge System Test: When enter the charging test, the tester will prompt "Loaded testing" .Note: Do not shut down the engine during the test. All electrical appliance and device are in OFF state. Turn on/off any electricalappliance in the vehicle during the test will affect the accuracy of the test result.Operate accordingly to increase the engine rotating speed to 2500turns, and keep for 5 seconds.Tester starts the charging volt test after increase rev detected.After the test finished, tester displays the effective charging volts, ripple test result and charging test result.NOTE: If no increase rev detected, it shall be the fault of generator regulator or connection with battery failed. Tester will try 3 times to further detect, if still failed, it will skip the increase rev detect and the test result displays "No Volt Output".Check the connection between generator and battery, then retest.Charge Test Result: 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: High. 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 14.7plusmn0.5V. 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.View Test Result: After entering the forth function, then press OK key you can view the final test result.Print Test Result: About Printing function, please contact with customer service to get the download link.Select A Language: After entering the language function, can press up/down key to choose it. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000;
