Operating Instructions
Powering On/Off
- Press the Power button (circular icon with a vertical line) to turn the device on.
- Press and hold the Power button to turn the device off.
- The device features an automatic shut-off function after 5 minutes of inactivity to conserve battery.
Calibration
Before each use, especially for pinless mode, it is recommended to perform a quick calibration.
- Turn on the device.
- Hold the device in the air, away from any materials or your body, ensuring at least 10 cm distance from the sensor.
- Press the SET button to initiate calibration. The display will show "CAL" and then indicate successful calibration.
Selecting Measurement Mode and Material Type
The MT35 offers two measurement modes: Pinless (non-destructive) and Pin-type (with external probe). It also supports 6 material types.
- Pinless Mode: This is the default mode when no external probe is connected. It's suitable for quick, non-invasive scans of walls (drywall, plaster, concrete).
- Pin-type Mode: Automatically activated when the external probe is connected to the Type-C port. This mode provides precise measurements for wood and construction materials.
- Material Selection: Press the SET button to cycle through the 6 material types: Softwood, Hardwood, Drywall, Plaster, Screed, and Concrete. Select the appropriate material for accurate readings.

Taking Measurements
- Pinless Measurement: Place the back sensor of the device flat against the surface you wish to measure. The reading will appear on the LCD screen. Ensure full contact for best results. Measurement depth is up to 19mm (0.75 inches).
- Pin-type Measurement: Gently push the pins of the external probe into the material. Ensure both pins penetrate the surface. The moisture percentage will be displayed.

Understanding Readings and Alarms
The large color LCD screen displays the moisture percentage, material type, and a dynamic bar graph. It also features a 3-color LED indicator and audio/visual alarms.
- Color Indicator:
- Green: Dry (low moisture)
- Yellow: Moist (medium moisture, risk zone)
- Red: Wet (high moisture, critical zone)
- Audio/Visual Alarm: The device will emit an audible alarm and flash the LED indicator when the moisture level exceeds a preset threshold for the selected material. The threshold is adjustable.
- Silent Mode: Press the Mute button (speaker icon) to toggle the audio alarm on/off.
- Data Hold: Press the HOLD button to freeze the current reading on the display. Press again to release.
