5. Орнотуу
5.1 Аппаратты кубаттоо
The load tester requires an external 12V power supply for operation. Connect the provided DC power adapter to the DC input port on the back of the unit. Alternatively, a USB-C power source can be used with the appropriate adapter board.

5.2 Зымдарды туташтыруу ыкмалары
The device supports both simplified two-wire and precise four-wire connection methods for the load. The four-wire system provides higher accuracy by separating the voltage sensing wires from the current carrying wires, thus compensating for voltage drops across the test leads.
- Two-Wire Method: Connect the positive and negative terminals of the power source to the A+ and A- terminals on the load tester. This method is simpler but may have slight voltage measurement inaccuracies due to lead resistance.
- Four-Wire Method: Connect the positive and negative terminals of the power source to the A+ and A- terminals (current paths). Additionally, connect separate voltage sensing wires from the power source to the V+ and V- terminals. This method ensures the most accurate voltagэ окуулар.

5.3 Баштапкы тилди орнотуу
Upon first power-up, the device may default to Chinese. Navigate through the menu using the buttons below the screen to locate the language settings and select "English" for easier operation.
6. Иштөө нускамалары
6.1 Интерфейске киришүү
The 2.4-inch color screen displays various parameters and settings. Familiarize yourself with the main interface and navigation buttons.

6.2 Иштөө режимдери
The load tester supports the following primary operating modes:
- Туруктуу ток (CC): Maintains a constant discharge current. Useful for battery capacity testing.
- Constant Voltage (CV): Туруктуу көлөмдү сактайтtage across the load.
- Constant Power (CP): Maintains a constant power dissipation.
- Constant Resistance (CR): Maintains a constant resistance across the load.
Select the desired mode from the menu and set the target parameters (e.g., current for CC mode, voltage for CV mode). The device will automatically adjust the load to maintain the set value.
6.3 Battery Capacity Testing (Constant Current Mode Exampле)
To test battery capacity:
- Батарея толугу менен заряддалганын текшериңиз.
- Connect the battery to the load tester using the four-wire method for optimal accuracy.
- Set the appropriate cutoff voltage for your battery type (e.g., 10.5V for a 12V LiFePO4 battery). This prevents over-discharge.
- Clear any previous test data to start with a clean slate.
- Select Constant Current (CC) mode.
- Set the desired discharge current. Start with a conservative value and monitor the MOS temperature. Do not exceed 99°C. Adjust current as needed, ensuring adequate cooling.
- The tester will display the discharged capacity (mAh or Ah) and energy (Wh). The test concludes when the battery voltage reaches the set cutoff voltage.
