5.5 Charging System Test 5.5.1 Preparation before testing If the car is flameout, please start the car. 5.5.2 Operation 1) When the car is in the starting state, connect the red test clamp to the battery positive pole, and connect the black test clamp to the battery negative pole. Attention must be made to good contact so as not to affect test results. 2) Press > > button to select Charging System Test, as follows: Select Items 4. Charging Test 1. Start Ability 3) Press to enter, The instrument will show the following picture: Start engine increase speed to 2500-3500 RPM then press ENTER 4) According to the prompt in the Step 3 to operate, and press to enter.
The test result will be displayed as follows: Max 14.10V ＜ 15.00V Cur 13.88V Min 13.58V ＞ 13.30V The current voltage is 13.88V, the standard maximum voltage is 15.00V (for 6V system, the standard maximum voltage is 7.50V; for 24V system, the standard maximum voltage is 30.00V), and the maximum voltage is 14.10V. The current voltage is 13.88V, the standard minimum voltage is 13.30V (for 6V system, the standard minimum voltage is 6.6V; for 24V system, the standard minimum voltage is 26.60V), and the minimum voltage is 13.58V. 5) Press the button will return to step (2). 5.5.3 Charging system problematic HT2018B(C) Battery System Tester 11
