5. Иштөө нускамалары
The BT138 is designed for one-step instant testing. Follow these steps to test your batteries:
5.1. Testing Cylindrical Batteries (AA, AAA, C, D, N, 1.5V/3.7V Lithium)
- Батареянын оң (+) жана терс (-) терминалдарын аныктаңыз.
- Connect the positive electrode of the BT138 (marked with '+') to the positive terminal of the battery.
- Connect the negative electrode of the BT138 (marked with '-') to the negative terminal of the battery.
- The LCD screen will immediately display the battery's voltage.

5.2. Testing 9V Batteries (6F22)
- Locate the dedicated 9V battery detection terminals on the BT138. These are typically marked for 9V battery detection.
- Align the positive and negative terminals of the 9V battery with the corresponding terminals on the tester. The tester may use magnetic attraction for secure connection.
- The LCD screen will display the 9V battery's voltage.

5.3. Testing Button Batteries (CR2032, LR44, L736)
- Place the button battery onto the designated contact points for button cells, ensuring correct polarity.
- The LCD screen will display the button battery's voltage.
5.4. Окууларды чечмелөө
- The LCD display shows the exact voltage.
- Generally, a higher voltage indicates a healthier battery.
- Эгерде батареянын томtage is too low (e.g., below 1.0V for a 1.5V battery), the screen may not display any reading. This indicates a fully depleted battery.
6. Техникалык тейлөө
- Тазалоо: Сыноочтун сыртын тазалоо үчүн жумшак, кургак чүпүрөктү колдонуңуз. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
- Сактагыч: Store the BT138 in a cool, dry place away from direct sunlight and extreme temperatures.
- Колдонуу: Аппаратты жерге түшүрүүдөн же катуу таасирлерден сактаныңыз.
7. Кыйынчылыктарды
- No display when testing a battery:
- Ensure the battery is correctly inserted with proper polarity.
- The battery might be completely depleted (dead). Try testing a known good battery to confirm tester functionality.
- Check for any debris or corrosion on the battery terminals or tester contacts.
- Туура эмес окуулар:
- Ensure good contact between the battery and the tester's electrodes.
- Verify the battery type is within the tester's supported range (1.2V-4.8V).
