3.1. Components

• Main Unit: Handheld device with LCD display and control buttons.
• Spherical Sensor: Integrated non-destructive sensor for surface measurements.
• Pin Probe: Detachable probe with two sharp pins for precise penetration measurements.
• USB Charging Cable: For recharging the internal battery.
• Replacement Pins: One pair of spare pins for the pin probe.
• Mini Key: For replacing the pin probe pins.

3.2. Display and Controls

The device features a 2.9-inch LCD with a switchable backlight for clear readability. Key indicators include:

• Moisture reading (percentage or relative value).
• Material type indicator (WOOD/BLD).
• Battery level indicator.
• Alarm status (visual LED, acoustic).
• HOLD function indicator.
• Auto Power Off (APO) indicator.

Control buttons include Power, Mode/SET, Hold, Mute, and Backlight.

4. Setup

4.1. Charging the Battery

The device is equipped with a rechargeable 1200 mAh Lithium Polymer battery. Before first use, or when the battery indicator shows low power, charge the device using the provided USB charging cable.

1. Connect the USB charging cable to the device's charging port.
2. Connect the other end of the USB cable to a standard USB power adapter (not included) or a computer's USB port.
3. The battery indicator on the LCD will show charging status.
4. Once fully charged, disconnect the cable.

4.2. Attaching the Pin Probe (Optional)

If you intend to use the pin measurement mode, attach the pin probe to the main unit.

1. Remove the protective cap from the pin probe.
2. Carefully align the connector of the pin probe with the corresponding port on the main unit.
3. Push firmly until it clicks into place.

5. Operating Instructions

5.1. Power On/Off

• To power on: Press and hold the Power button () for approximately 2 seconds.
• To power off: Press and hold the Power button again for approximately 2 seconds. The device also features an Auto Power Off (APO) function after 10 minutes of inactivity.

5.2. Mode Selection (Pinless vs. Pin)

The MT69 offers two measurement modes. Use the Mode/SET button to switch between them.

5.3. Pinless Measurement (Spherical Sensor)

This mode is ideal for quick, non-destructive scanning of surfaces to identify potential moisture areas. It provides relative values.

1. Ensure the device is in pinless mode (indicated on the LCD).
2. Place the spherical sensor flat against the surface of the material you wish to test.
3. Move the device slowly across the surface. The display will show relative moisture values from 0 to 100.
4. The measurement depth for this mode is approximately 20-40 mm.
5. The device will automatically calibrate when placed on a dry surface.

5.4. Pin Measurement

Use this mode for accurate percentage moisture readings by penetrating the material with the pins.

1. Ensure the pin probe is attached and the device is in pin mode (indicated on the LCD, showing % values).
2. Carefully push the pins into the material to be tested. Ensure both pins fully penetrate the surface.
3. The display will show the moisture content as a percentage.
4. Measurement ranges: Wood (5-52%), Building Materials (BLD) (2-30%).

5.5. Alarm System

The MT69 features an intelligent alarm system to alert you to high moisture levels.

• Visual Alarm: A three-color LED indicator (green, blue, red) provides a quick visual assessment of moisture levels.
• Acoustic Alarm: An audible beep will sound when moisture levels exceed a set threshold.
• Adjustable Limits: In spherical sensor mode, alarm limits can be adjusted via the Mode/SET button. This feature is not available in pin mode.
• Mute Function: Press the Mute button to silence the acoustic alarm for noise-sensitive environments.

5.6. HOLD Function

Press the HOLD button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.7. Self-Test Function

The device includes a self-test function for quality assurance. Refer to the on-screen prompts or specific instructions in the quick start guide for activation.

5.8. Important Measurement Considerations

When using the spherical sensor, ensure there is no metal within approximately 5 cm of the area being tested, as metal can interfere with readings.

6. Maintenance

6.1. Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.

6.2. Battery Care

To prolong battery life, avoid fully discharging the battery frequently. Recharge the device when the low battery indicator appears. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.

6.3. Replacing Pin Probe Pins

The pin probe pins are replaceable. If the pins become dull or damaged, use the provided mini key to unscrew and remove the old pins, then carefully screw in the new replacement pins.

6.4. Storage

Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the protective cap on the pin probe when not in use.
