6. Operating Instructions

6.1 Powering On/Off

Press the power button (usually marked with a power symbol) to turn the device on. Press and hold the power button to turn it off. The device may also have an auto-off feature to conserve battery life.

6.2 Selecting Measurement Mode

Press the "MODE" button to cycle through different material types: Wall, Masonry, Softwood, Hardwood. Select the mode that best matches the material you are testing for accurate readings.

6.3 Taking a Measurement

1. Ensure the correct material mode is selected.
2. Place the back of the meter flat against the surface you wish to measure.
3. Apply a consistent, firm pressure (approximately 2.5 KG is recommended for accurate results, as shown in Figure 6.3).
4. The moisture percentage will be displayed on the LCD screen.

Figure 6.3: For accurate results, apply approximately 2.5 KG of pressing force when taking measurements.

6.4 Interpreting Readings

The color LCD and LED bar graph provide visual indicators of moisture levels:

• Green (DRY): Indicates low moisture content.
• Yellow (MID): Indicates moderate moisture content.
• Red (WET): Indicates high moisture content, potentially requiring further investigation.

Figure 6.4: The display clearly indicates moisture levels as DRY, MID, or WET using color-coded indicators.

Note: The measured value is relative. When scanning an area quickly to detect moisture, use the HOLD key to lock abnormal readings for recording and analysis.

Important: Testing on pure drywall is not recommended as its low density can lead to inaccurate readings. Actual readings vary with moisture and material density.

6.5 Hold Function

Press the "HOLD" button to freeze the current reading on the display. This is useful for noting down specific measurements or when measuring in hard-to-reach areas. Press the "HOLD" button again to release the reading and resume live measurement.

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the meter in its provided storage bag in a cool, dry place when not in use. Remove the battery if storing for extended periods to prevent leakage.
• Battery Replacement: Replace the 9V battery when the low battery indicator appears on the display.
