5.4.2 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 Maximum Load Test, as follows: Select Items 3. Run Max Load 4. Charging Test 3) Press to enter, The instrument will show the following picture: Load all on increase speed to 2000-2500 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:
Run Load Test Cur 12.86V Min 12.30V ＜ 12.80V The tester respectively shows the current voltage 12.86V, the standard voltage is 12.80V (for 6V system, the standard voltage is 6.40V; for 24V system, the standard voltage is 25.60V), and the minimum voltage is 12.30V. 5) The lowest voltage. If the voltage is greater than 12.8V (for 6V system, the voltage is greater than 6.40V; for 24V system, the voltage is greater than 25.60V), the system is normal. 6) Press the button will return to step (2).
5.4.3 System problematic If the voltage is less than 12.8V (for 6V system, the voltage is less than 6.40V; for 24V system, the voltage is less than 25.60V), please check whether the generator belt is worn out and can not be used, and whether the wire is short-circuit.
