4.1 การชาร์จแบตเตอรี่

The MT28 meter is equipped with a built-in 1200mAh rechargeable battery. Before first use, or when the battery indicator on the display shows low power, charge the device using the provided Type-C charging cable.

1. Connect the Type-C end of the cable to the charging port on the meter.
2. Connect the USB-A end of the cable to a standard USB power adapter (not included) or a computer USB port.
3. The battery indicator on the display will show charging status. Once fully charged, the indicator will show full.

4.2 การเปิด/ปิดเครื่อง

กดปุ่มเปิด/ปิดค้างไว้ (U) to turn the meter on or off.

5. คู่มือการใช้งาน

5.1 Pinless (Non-Invasive) Mode

The pinless mode uses a spherical sensor to scan surfaces for moisture without causing damage. This mode provides relative readings and is ideal for quick assessments over large areas.

1. ตรวจสอบให้แน่ใจว่ามิเตอร์เปิดใช้งานอยู่
2. Select the pinless mode (often indicated by a spherical icon on the display or a dedicated button).
3. Place the spherical sensor firmly and flat against the surface of the material to be tested.
4. Ensure your fingers are clear of the scanning area on the back of the meter to avoid inaccurate readings.
5. Read the moisture level displayed on the LCD. The tri-color LED indicator will also provide a visual cue (green for dry, blue for moist, red for wet).

5.2 Pin-Type Mode

The pin-type mode uses two sharp pins to penetrate the material, providing precise percentage readings of moisture content. This mode is suitable for wood and building materials where direct contact is acceptable.

1. Connect the wired remote pin-type probe to the meter.
2. Remove the protective cap from the pins.
3. Carefully push the pins into the material to be tested. Ensure both pins are fully inserted and making good contact.
4. อ่านค่าเปอร์เซ็นต์ความชื้นtage on the LCD. The tri-color LED indicator will also provide a visual cue.
5. After measurement, carefully withdraw the pins and replace the protective cap.

5.3 Material Selection and Measurement Range

The meter supports different material types with specific measurement ranges:

• Wood Mode: Measures moisture content from 5% to 52%.
• Building Material (BLD) Mode: Measures moisture content from 2% to 30%.
• Pinless (Induction/Spherical) Mode: Provides relative readings from 0 to 100.

Use the mode selection button on the meter to switch between Wood and Building Material modes for pin-type measurements. The pinless mode is typically selected automatically or via a dedicated button.

5.4 Alarm Settings and HOLD Function

The MT28 features customizable alarm thresholds and a data hold function.

• Customizable Alarm: You can set specific moisture thresholds for the audible alarm. When the measured moisture exceeds this threshold, the alarm will sound, and the LED indicator will turn red. Refer to the meter's on-screen menu or specific buttons (e.g., 'SET') for adjusting these values.
• ฟังก์ชั่น HOLD: Press the 'HOLD' button to freeze the current reading on the display. This is useful for taking readings in hard-to-reach areas where direct viewing of the display is difficult. Press 'HOLD' again to release the reading.

5.5 Important Measurement Notes

• หลีกเลี่ยงการรบกวนจากโลหะ: When using the pinless mode, ensure there is no metal (e.g., pipes, electrical wires, rebar) within 2 inches (approximately 5 cm) of the testing area. Metal objects can significantly interfere with readings, leading to inaccurate results.

6. การบำรุงรักษา

• การทำความสะอาด: Wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• การดูแลรักษาเข็มหมุด: Keep the pin probes clean and free of debris. Replace bent or dull pins using the provided wrench and replacement pins.
• พื้นที่จัดเก็บ: Store the meter in its original packaging or a protective case in a dry environment when not in use. Ensure the protective cap is on the pin probes.
• แบตเตอรี่: For long-term storage, ensure the battery is partially charged (around 50%) and recharge it every few months to maintain battery health.
