Power supply voltage: DC4.5-6V (micro USB interface) Working current: no more than 70mA Discharge voltage: 1.00V-15.00V, resolution 0.01V Termination voltage range: 0.5-11.0V Support through current: no more than 3.000A, resolution 0.001A Voltage measurement error: less than 1%+0.02V Current measurement error: less than 1.2%+-0.002A Battery capacity range: 9999Ah (1Ah=1000mAh) when the value is large, the decimal point is shifted and switched, when it is less than 10Ah, it will be displayed as X.XXX, and when it reaches 10Ah, it will be displayed as XX.XX.
Error code and meaning: Err1: The battery voltage is higher than 15V Err2: The battery voltage is lower than the set termination voltage Err3: The battery cannot withstand the load discharge current or the internal resistance of the circuit is too large Err4: Excessive current (current exceeds 3.1A)
Instructions: 1. The battery under test should be fully charged first. 2. Connect the positive pole of the battery under test to the positive input, and the negative pole to the negative input. Do not reverse the connection (reverse connection with a load may damage the circuit)! Connect the load to the positive output and negative output, and power the tester's micro USB to the working power (desktop or laptop USB is not available), and the battery voltage is displayed at this time. 3. To start the test directly, you only need to press the "OK" button. The tester can automatically set a suitable termination voltage according to the full charge voltage of the battery, and will flash 3 times before starting the test. If you need to manually set the end voltage, you only need to press the "+" or "-" button to modify the battery voltage display state. The end voltage display starts with P and the back represents the voltage value with a resolution of 0.1V. After setting, press "OK" "start testing. 4. After the test starts, the tester will turn on the electronic switch that controls the load, and the test process data display will be displayed in turn among the discharge capacity (Ah), the current discharge current (A) and the battery voltage (V). When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the displayed data stays on the capacity (Ah) and flashes quickly with the corresponding indicator. At this time, the displayed capacity is the actual discharge capacity of the battery, press it once "OK" can stop the flashing and make the data display stably, press the "OK" button again to restore to the just-powered state, you can replace the battery to test the next section
