3. დაყენება

1. ბატარეის ჩასმა: Install the 18650 battery to be tested into the working battery compartment. Ensure correct polarity.
2. დაკავშირება ძალა: Use the provided Type-C to USB cable to connect the Type-C power supply port on the tester to a 5V power source (e.g., a USB wall adapter or computer USB port).
   

   სურათი: Diagram illustrating the connection of a 5V power adapter via the Type-C port to power the tester.

   შენიშვნა: An external 5V/1A power supply is required for the Charging (CHG) and Automatic (AUTO-TEST) modes to function correctly. For Discharge (DSG) mode only, an external power supply is not strictly necessary, but it is recommended for stable operation and display.

4. ზოგადი ოპერაცია

1. ჩართვა: After connecting the power supply and inserting the battery, the device will power on and display information on the LCD.
2. აირჩიეთ რეჟიმი: Use the "Adjustment" button to cycle through the available operating modes: AUTO (Automatic), CHG (Charge), and DSG (Discharge). The default mode is AUTO.
3. დაწყება ტესტი: Once the desired mode is selected, press the "Start/Stop" button to begin the test program.
4. პროგრესის მონიტორინგი: The LCD will display real-time data such as voltage, current, capacity, and elapsed time.
5. ტესტის დასასრული: The program will automatically stop when the test is complete, or you can manually stop it by pressing the "Start/Stop" button again. The status indication on the display will show "STOP".

5. ოპერაციული რეჟიმები

The tester features three primary operating modes:

• AUTO (Automatic Mode): This mode performs a full charge-discharge-charge cycle to determine the battery's capacity. The battery is first charged, then discharged to measure capacity, and finally charged again to a full state. This provides a comprehensive capacity measurement.
• DSG (Discharge Mode): In this mode, the tester discharges the battery to a preset stop voltage (typically 3V). It measures and displays the discharged capacity and energy. This mode is useful for determining the usable capacity of a battery from its current charge level.
• CHG (Charge Mode): This mode charges the battery to its full voltage (typically 4.2V). While charging, the device records the elapsed time but does not measure capacity or energy. This mode is primarily for charging the battery.

6. Language Switch (Chinese/English)

To switch the display language between Chinese and English, follow these steps:

1. გამორთვა: დარწმუნდით, რომ მოწყობილობა გამორთულია.
2. Initiate Switch: Press and hold the "Menu" button, then power on the device. Release the "Menu" button once the screen illuminates.
3. დენის ციკლი: Wait approximately 10 seconds after the screen lights up, then power off the device.
4. Complete Switch: Power on the device again. The language should now be switched.

8. Დიაგნოსტიკა

• მოწყობილობა არ ჩართულია:

  Ensure the Type-C power supply cable is securely connected to a functional 5V power source. Verify the power source is active.

• No Measurement Data Displayed:

  Confirm that the 18650 battery is correctly inserted into the working battery compartment with the correct polarity. Press the "Start/Stop" button to initiate a test cycle.

• არაზუსტი წაკითხვები:

  Ensure the battery terminals are clean and making good contact with the tester's contacts. The measurement error for internal resistance is approximately 10%.
• Charging/Discharging Not Initiating:

  For CHG (Charge) and AUTO (Automatic) modes, an external 5V/1A power supply must be connected. Ensure the correct mode is selected using the "Adjustment" button before pressing "Start/Stop".

• Simultaneous Testing Limitation:

  მნიშვნელოვანი შენიშვნა: The 18650 battery compartment and the external Type-C discharge interface cannot be used for testing simultaneously. Attempting to do so may lead to incorrect results or device malfunction.
