Feature:1. Superior Materials: The housing is made of TPR materials, more comfortable to use and more comprehensive protections.2. Color LCD Display: 3.2inch large LCD color screen for display functions status measuring results, analogue bargraph shows the battery lifespan after finishing tests.3. Multiple Test Function: Support for battery test (battery voltage, internal resistance, discharge current), starts-test (discharge performance), and load test (generator performance) function.4. Continuously Test: Can check the battery status and the discharging ability, by applying low frequency signal it will not damage the battery by applying large loading for discharging, support continuously.5. Illumination Lamp Function: This lamp can illuminate the engine compartment, and provide illumination in dark and complex working conditions.6. Support Both 12.0V and 24.0V Battery: Automatically identify 12.0V or 24.0V batteries, one button selection of intelligent measurement.7. Multiple Protections: Support input overvoltage, reverse polarity connection, high voltage connection protections and poor contacts of test clip.8. Innovative Temperature Function (ET2202 only): Convenient for engine temperature and air conditioning temperature measurement, more practical.9. Easy Operation: Allow to connect batteries in cars It do not need to take the battery out for test. Battery detection is easy to operate, easy to understand battery status, the greater the CCA value of the battery, the smaller the internal resistance.10. High Compatibility: Various types of batteries can be selected, support matching multiple types of batteries, EN, IEC, CCA, SAE, DIN.11. Copper Wire Clip: All copper material of red and black wire clamp, more than 10000 occlusion tests, more reliable to use.12. Two modes Optional: Two types are available, you can choose ET2201 or ET2202 depending on your needs.13. ET2201: battery test (battery voltage, internal resistance, discharge current), starts-test (discharge performance), and load test (generator performance).14. ET2202: temperature test, charging capacity test, battery test (battery voltage, internal resistance, discharge current), starts-test (discharge performance), and load test (generator performance).Specification:This intelligent battery tester has 3.2inch large LCD color screen for display functions status measuring results, analogue bargraph shows the battery lifespan after finishing tests.
