4. Setup

4.1 Battery Installation

1. Locate the battery compartment cover on the back of the device.
2. Use the provided screwdriver to loosen the screw securing the battery cover.
3. Remove the cover.
4. Insert three (3) AAA alkaline batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery cover and tighten the screw.

4.2 Initial Calibration

1. Press the Power Button to turn on the device.
2. Hold the device in the air, away from any objects, and press the MEAS Button.
3. The device will perform an automatic calibration, typically completing within 3 seconds. The display will show "CAL" briefly, indicating successful calibration.
4. The device is now ready for measurement. It is recommended to recalibrate after each measurement or if moving to a significantly different environment.

5. Operating Instructions

5.1 Taking a Measurement

1. Ensure the device is calibrated (refer to Section 4.2).
2. Place the spherical sensor flat against the surface of the material you wish to measure.
3. Move the sensor slowly across the surface. The display will show real-time moisture readings.
4. The measurement depth is approximately 20-40mm.
5. Avoid placing the sensor near metal objects or within 10 cm of corners, as this can affect accuracy.
6. To obtain a reference value, first measure a known dry area of the same material.

5.2 Understanding Readings and Alarms

• The main digital display shows the current moisture value (0.0-100.0). Note that these are relative values, not absolute percentages for all materials.
• The analog color bar provides a quick visual guide:
  • Green: Indicates a dry condition.
  • Yellow: Indicates a risk of moisture.
  • Red: Indicates a wet condition.
• The device features an audible alarm. This alarm activates when the measured moisture level exceeds a user-defined threshold.
• To set the alarm threshold:
  1. Press the SET Button to enter alarm setting mode.
  2. Use the Up/Down Arrow Buttons to adjust the desired alarm value.
  3. Press SET again to confirm and exit.
• The display also shows MAX and MIN values, representing the highest and lowest readings recorded during the current measurement session.
• The device has a Data Hold function. Press the appropriate arrow button (often the 'Up' arrow) to freeze the current reading on the display. Press again to release.

6. Applications
