ALL-SUN EM571 12V Automotive Vehicle Car Battery Tester 3 in 1 Multifunction Check Meter Digital Analyzer Diagnostic

 

ALL-SUN EM571 is designed to test 12V automotive lead acid storage batteries and 12V automotive starting/charging systems. It uses advanced conductance testing technology and can easily, quickly and accurately test the actual cold cranking amps capability of automotive battery, health state of automotive battery, automotive cranking system and charging system.

 

Features:

 

1. 3 in 1 Multifunction Check Meter: Main functions of this tester include 12V automotive battery test, 12V automotive cranking system test, and 12V automotive charging system test functions.

 

2. Tests all 12V automotive cranking lead acid batteries, including ordinary lead acid batteries, AGM flat plate batteries, AGM spiral batteries, Gel batteries, etc.

 

3. Reverse polarity connection protection. Reverse polarity connection will not damage the tester or affect the vehicle and battery under test.

 

4. Directly tests low battery, no need to fully charge battery before test.

 

5. Test standards include most battery standards around the world: CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB.

 

Supported Languages: English, Russian, Japanese, Chinese,

 

Analysis for Possible Charging System Test Results:

 

1. Charging Voltage: Normal

The charging system shows that the alternator output is normal, no problem detected.

 

2. Charging Voltage: Low

Charging voltage of the charging system is low.

Please check whether the driving belt of the alternator is loose or broken, and check whether the connections between the alternator and the vehicle battery are good.

If the belt and the connections between the alternator and the vehicle battery are good, the alternator is likely faulty.

 

3. Charging Voltage: high

 

4. No Voltage Output

No alternator output voltage is detected. Please check whether the alternator's connections are good and whether the driving belt of the alternator is tight enough.

 

5. Diode Test

Through the test of charging current ripple, you can determine whether the rectifier diodes are good. If the ripple voltage is too high, it means that one or more rectifier diodes are damaged or the alternator stator is damaged. Please check for the bad diode(s) and replace all bad diodes, and check the alternator stator.
