Operating instructions:
I. Function mode setting (default factory electronic load mode): Press and hold "ON/OFF" at the same time to the tester energized until the display Fun * and then release the button, at this time into the function setting menu. By rotating the knob to change the setting, by pressing "ON/OFF" to switch to the next step, set in the following order:
1. Mode setting "Fun1" is electronic load mode, "Fun2" is battery capacity test mode.
2. Buzzer switch setting "bEon" buzzer on, "bEoF" buzzer off.
3. Display brightness setting "Lt-1" "Lt-2" "Lt-3", three brightness levels can be selected. Finish this again press "ON/OFF" to save and exit the setting. After that, the tester will restart and enter into normal working condition.
Second, the electronic load mode:
1. Turn on the 12V power supply, make sure it is in the stop state ("RUN" lamp does not light up, otherwise press the "ON/OFF" off) under the connection of the power supply under test to the power input port (P + P-), such as the use of four-wire connection, please also connect the voltage detection line to the (V + V-) socket. If using four-wire connection method, please connect the voltage detection line to the (V+V-) socket at the same time. If the measured power supply voltage is higher than 1V, the voltage will be displayed automatically, and the "L-4" lamp will light up when it is recognized as 4-wire mode. Note: Do not touch the radiator with the screwdriver when wiring, and do not connect the negative pole anyway.
2. Set the current and the lower limit voltage through the knob, rotate the knob to set the value of the current setting position, press the knob to switch the setting digit, the number of the current setting position will blink, more than 3 seconds of inactivity will automatically exit the setup back to the normal display of voltage and current.
3. Press "ON/OFF", the load starts to run, "RUN" lights up, the circuit applies the set discharge current to the input power supply under test, and at the same time, the actual input load voltage is displayed on the upper line, when the voltage is lower than the set lower limit voltage, "RUN" light flashes and accompanied by a short buzzer alarm. When the voltage falls below the set lower limit voltage, "RUN" light flashes and accompanied by a short buzzer alarm.
4. The current can be modified at any time during the test, if the lower limit voltage needs to be modified, the load must be turned off before modification.
Note: When in alarm state, the current can only be adjusted down, not up! Tester automatic power-down save function can save the set parameters and operating status, when the power failure to resend power will be restored before the power failure of the complete state and data.

Third, the battery capacity test mode:
1. The battery under test should be fully charged with a special charger first!
2. Power on the tester to enter the battery capacity test mode, connect the positive and negative battery current lines to the P+P- terminals, if you use the four-wire fixture test, please connect the four-wire fixture voltage test interface positive and negative to the V+V- port. The tester will display the battery voltage, if the 4-wire voltage test line is connected correctly, the "L-4" lamp will light up at the same time.
3. Set the discharge current and discharge termination voltage by rotating the knob (please refer to the description of II:2), after setting, press "ON/OFF", the tester will firstly detect the battery and the line, and then enter into the test, if there is a fault code, please refer to the back of the description.
4. During the testing process, the upstream digital tube will display the battery voltage, current discharge capacity Ah and current discharge energy Wh. When the discharge is finished (battery voltage is lower than the set voltage), the tester will display the data in Ah and flash rapidly, accompanied by a buzzer alarm sound.
5. Press the knob or start/stop switch to stop the alarm, you can rotate the knob to view the battery discharge data including discharge capacity Ah, discharge energy Wh and platform voltage V. Press "ON/OFF" again to clear the data and restore to the initial setup interface before testing the next battery.

Supplementary notes:
1. You can adjust the discharge current at any time during the battery test, if you need to readjust the termination voltage, you can pause the discharge modification by clicking "ON/OFF" (the pause discharge will return to the setting page, the discharged data will not be lost, at this time, long-press "ON/OFF" can clear the data). (the discharged data will not be lost, then long press "ON/OFF" to clear the data).
2. Tester power down automatically save the ability to record the set parameters, and in the test process and the end of the test alarm state occurs when the power failure to record all the parameters and the state of the re-powered all automatically restored.
Fault protection code and meaning:
Err1: capacity test battery voltage is too high.
Err2: Battery voltage is lower than the set termination voltage, not connected to the battery or reverse battery.
Err3: The internal resistance of the line is too large or the battery can not withstand the set discharge current.
Err4: Circuit failure.
Po-L: Power supply voltage is too low or insufficient power.
Po-H: Power supply voltage too high.
otP: Overheat protection.
Ert: Temperature probe failure or too low temperature.
ouP: Voltage too high in electronic load mode.
