Operation instructions:

1. Function mode setting default factory setting is electronic load mode: Press and hold "ON/OFF" to power on the , and release the on until Fun* is displayed. At this time, enter the function setting menu. Change the setting by rotating the knob, and switch to the next step by pressing "ON/OFF". Set in the following order:

1. Mode setting "Fun1" is electronic load mode, "Fun2" is battery capacity test mode.

2. switch setting "bEon" on, "bEoF" off.

3. Display brightness setting "Lt-1" "Lt-2" "Lt-3", three brightness levels are optional. After completing this item, press "ON/OFF" again to save and exit the setting. Then the restarts and enters normal working state.

2. Electronic load mode:

1. Connect the 12V working power supply and turn on the machine. e sure it is in the stopped state the "RUN" light is not on, otherwise press "ON/OFF" to turn it off. Connect the power supply under test to the power input port P+P-. If you use the four-wire connection method, please connect the voltage line to the V+V- socket at the same time. If the voltage of the power supply under test is higher than 1V, the voltage will be automatically displayed. When it is identified as a four-wire mode, the "L-4" light will light up. Note: Do not touch the radiator with the screwdriver when wiring, and do not connect the negative pole.

2. Set the current and 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 di. The number of the current setting position will f. If there is no operation for more than 3 seconds, it will automatically exit the setting and return 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 the upper line displays the actual input load voltage. When the voltage is lower than the set lower limit voltage, the "RUN" light fes and the al shortly.

4. The current can be modified at any time during the test process. If you need to modify the lower limit voltage, you must first turn off the load before modifying it.

Note: When in alarm state, the current can only be adjusted down but not up! The automatic power-off saving function of the can save the set s and operating status. When the power is off and then re-powered, the status and data before the power outage will be completely restored.

III. Battery capacity test mode:

1. The battery to be d should be fully charged with a dedicated charger first!

2. Power on the to enter the battery capacity test mode, connect the positive and negative poles of the battery current line to the P+P- terminal. If a four-wire fixture is used for testing, please also connect the positive and negative poles of the four-wire fixture voltage test interface to the V+V- port. The will display the battery voltage. If the four-wire voltage test line is connected correctly, the "L-4" light will light up at the same time.

3. Set the discharge current and discharge termination voltage by rotating the knob refer to 2: 2. Description for specific methods. After setting, press "ON/OFF". The first detects the battery and circuit, and then enters the test. If a fault code appears, please refer to the following instructions.

4. During the test, the uplink dial tube will rotate to display the battery voltage, current discharge capacity Ah and current discharge energy Wh. When the discharge is completed the battery voltage is lower than the set voltage, the display data stays at Ah and fes quickly, accompanied by a rapid alarm.

5. Press the knob or the start-stop switch to stop the alarm. You can view the battery discharge data including discharge capacity Ah, discharge energy Wh and platform voltage V by rotating the knob. After pressing "ON/OFF" again, clear the data and restore to the initial setting interface before testing the next battery.

Additional instructions:

1. The discharge current can be adjusted at any time during the battery test. If you need to readjust the termination voltage, you can press "ON/OFF" to pause the discharge modification pausing the discharge will return to the setting page, and the discharged data will not be lost. At this time, press "ON/OFF" to clear the data.

2. The can automatically save the set s when it loses power, and record all s and status when the power is off during the test process and the alarm state at the end of the test. All are automatically restored after power is restored.

Fault protection code and meaning:

Err1: The capacity test battery voltage is too high.

Err2: The battery voltage is lower than the set termination voltage, the battery is not connected or the battery is connected in re.

Err3: The line internal resistance is too large or the battery cannot withstand the set discharge current.

Err4: Circuit fai.

Po-L: The power supply voltage is too low or the power is insufficient.

Po-H: The power supply voltage is too high.

otP: Overheat protection.

Ert: The temperature probe is faulty or the temperature is too low.

ouP: The voltage is too high in the electronic load mode.
