    Battery Tester BT300 TURN LIGHTS OFF Now the tester detects the surface charge has been eliminated, turn lights off as prompted, then press OK key. The tester will recover automatic test OUT-OF-VEHICLE means battery is not connected with any of the vehicle loaded, i.e.
  • Page 10 Battery Tester BT300 press OK key to confirm. When it's IN-VEHICLE test, battery installation way shall also be selected, e.g. TOP, SIDE or REMOTE (This selection is no need for OUT-OF-VEHICLE), then press OK key to confi rm. REMOTE is adopted for some in vehicle battery which is too tightly installed to use the test clamps to connect the battery poles.

    Battery Tester BT300 SOH:39% SOC:20% 12.08V 310A Rating 500A CHARGE-RETEST Unstable battery shall be recharged and retested to avoid error. If same test result appears after recharge and retest, the battery is regarded as damaged, replace the battery. Attention: If "Replace" resulted from IN-VEHICLE mode, it might be the reason that vehicle cable is not well connected with the battery.

    Battery Tester BT300 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 cranking test is abnormal, battery test result will also be displayed at the same time.
  • Page 17 Battery Tester BT300 Tester will do the following tests in a sequence: For ripple test, tester will display the real time ripple and meanwhile, shows ripple volt and charging volt values at the bottom line. It takes approx. 6 seconds for the ripple test.
  • Page 18 Battery Tester BT300 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".
  • Page 19: System Test

    Battery Tester BT300 4) No Volt Output: No generator volt output detected. Check the generator connection cable and the belt whether they are normal. 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.
