1. Introduction
The Neoteck 6-in-1 Pinless Moisture Meter (Model MT35) is designed for non-destructive moisture detection in various materials. It utilizes electromagnetic field (EMF) technology to measure moisture content up to 19mm (0.75 inch) below the surface without causing damage. This device offers six measurement modes for different materials: soft wood, hard wood, drywall, plaster, screed, and concrete. It features audible and visual alarms, a 2.9-inch LCD display, customizable thresholds, and a rechargeable battery.

4.2 Initial Power On
Press the power button (usually marked with a power icon) to turn on the device. The LCD display will illuminate, and the device will be ready for use.
5. Operating Instructions
5.1 Selecting Measurement Mode
The device offers six distinct measurement modes for different materials. It is crucial to select the correct mode for accurate readings.
- Press the "Materials Selection" button (often labeled with material icons or a mode button) to cycle through the available modes: Soft Wood, Hard Wood, Drywall, Plaster, Screed, Concrete.
- The selected material type will be displayed on the LCD screen.
Figure 4: 6-in-1 Measurement Modes.
5.2 Taking a Measurement
Follow these steps to obtain a moisture reading:
- Ensure the device is powered on and the correct material mode is selected.
- Place the back of the moisture meter (where the sensor is located) flat against the surface of the material you wish to measure.
- Apply gentle, even pressure to ensure full contact between the sensor and the material.
- Read the moisture percentage displayed on the 2.9-inch LCD screen. The device will provide a numerical reading and a visual bar graph indicating dry, moist, or wet conditions.

5.3 Understanding Alarms and Indicators
The MT35 features both audible and visual alerts to indicate moisture levels, enhancing the reliability of warnings.
- 3-Color LED Indicator: Located at the top of the device, this LED changes color based on moisture levels:
- Green: Indicates a dry condition.
- Yellow: Indicates a moist condition.
- Red: Indicates a wet condition.
- Audible Alarm: A beeping sound will activate when the moisture level reaches the "wet" threshold. This can be muted by pressing the "Buzzer switch / Automatic power off switch" button.
- Screen Simulation Bar: A graphical bar on the LCD provides a visual representation of the moisture level (Dry, Moist, Wet).

5.4 Customizing Alarm Thresholds
You can adjust the moist and wet alarm thresholds for each material type to suit specific project requirements.
- Press the "SET" button once to enter the alarm threshold setting mode.
- Use the up/down arrow buttons to adjust the threshold values for moist and wet conditions.
- Press the "SET" button twice to exit the setting mode and save your changes.

5.5 Data Hold Function
To freeze the current reading on the display for easier viewing or recording, press the "HOLD" button. Press it again to release the hold function and resume live readings.
5.6 Automatic Power-Off (APO)
The device will automatically power off after 5 minutes of inactivity to conserve battery. This feature can typically be toggled on/off by pressing and holding the "Buzzer switch / Automatic power off switch" button (often labeled with APO).
6. Maintenance
6.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the sensor area on the back of the device is kept clean and free of debris.
6.2 Storage
Store the moisture meter in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan. Use the provided storage pouch for protection.
7. Troubleshooting
7.1 Inaccurate Readings
- Incorrect Material Mode: Ensure the correct material mode (Soft Wood, Hard Wood, Drywall, Plaster, Screed, Concrete) is selected for the surface being tested.
- Insufficient Contact: Ensure the sensor is placed flat and firmly against the surface. Uneven contact can lead to inconsistent readings.
- Metal Interference: Check for metal objects (pipes, electrical wiring, studs, nails) within the measurement area. Metal can interfere with EMF readings. Keep the device at least 2 inches (5 cm) away from metal objects.
- Material Thickness: For materials 20-40 mm thick, the reading shows moisture at approximately 20 mm depth. Readings may be less accurate for materials outside this range or very thin materials.
- Sensor Contamination: Clean the sensor area on the back of the device with a soft, dry cloth.
7.2 Device Not Powering On
- Low Battery: Charge the device using the provided Type-C cable and a 5V USB adapter.
- Faulty Cable/Adapter: Try a different Type-C cable and USB power adapter to rule out accessory issues.
7.3 No Audible Alarm
- Mute Function Active: Press the "Buzzer switch / Automatic power off switch" button to unmute the alarm.
- Moisture Below Threshold: The alarm only sounds when the moisture level exceeds the "wet" threshold. Check the display for current readings and ensure the thresholds are set appropriately.
