- While taking a measurement, short press the Hold & °C/°F button (). The 'HOLD' icon will appear on the display.
- Press the button again to release the hold function and resume live readings.
4.5 Switching Temperature Units
The device can display temperature in Celsius (°C) or Fahrenheit (°F).
- Long press the Hold & °C/°F button () to toggle between °C and °F.
4.6 Interpreting Moisture Readings
The device provides a clear indication of moisture levels based on the selected material mode. Refer to the table below for general guidelines:
| Moisture Level | Soft Wood | Hard Wood | Packing | Building |
|---|---|---|---|---|
| DRY | <20% | <12% | <13% | <17% |
| MID | 20-26% | 12-16% | 13-21% | 17-20% |
| WET | >26% | >16% | >21% | >20% |
5. Maintenance
5.1 Cleaning
- After each use, wipe the measurement pins and the device body with a clean, dry cloth.
- Do not use abrasive cleaners or solvents.
5.2 Pin Replacement
Refer to Section 3.2 for detailed instructions on replacing the measurement pins.
5.3 Battery Replacement
- When the battery status icon indicates low power, replace the batteries promptly to ensure accurate readings.
- Refer to Section 3.1 for battery installation instructions.
5.4 Storage
- Always cover the sharp measurement pins with the protective cap after each use.
- Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
6. Safety Precautions
- The measurement pins are very sharp. Handle with care and always replace the protective cap after use to prevent injury.
- Do not let the probe come into contact with charged objects or live electrical circuits. This can cause electric shock or damage the device.
- Keep the device out of reach of children.
- Do not attempt to disassemble or modify the device. Repairs should only be performed by qualified personnel.
7. Troubleshooting
7.1 Device Not Turning On
- Check if the batteries are installed correctly with the correct polarity.
- Replace old or depleted batteries with new ones.
7.2 Inaccurate Readings
- Ensure the correct material mode is selected for the material being tested.
- Verify that the measurement pins are clean and not bent or damaged. Replace if necessary.
- Make sure the pins are fully inserted into the material and making good contact.
- If there is visible moisture on the surface, wipe it dry with a cloth and wait 3 minutes before testing.
- Test multiple spots on the material for a more representative reading.
7.3 Display Issues
- If the display is dim or flickering, replace the batteries.
- Extreme temperatures or humidity can affect display performance. Operate within specified environmental conditions.

9. User Tips
- Surface Preparation: Always ensure the surface of the material is clean and dry before taking a measurement. If there is visible moisture, wipe it dry and wait at least 3 minutes for the surface to normalize.
- Multiple Readings: For best results, take several readings in different spots on the material. This helps account for variations in moisture distribution.
- Pin Penetration: Ensure the pins penetrate the material sufficiently to get an accurate internal moisture reading, especially for thicker materials.
- Environmental Factors: Extreme ambient temperatures or humidity can influence readings. Allow the meter to acclimate to the environment where measurements are being taken.
- Calibration Check: While not explicitly mentioned, it's good practice to periodically check the meter's accuracy using a known dry sample if available, or by comparing readings with another trusted meter.
