Operation and Settings
Alarm Set Mode
By pressing the SET button, you can enter the alarm set mode. If the meter is already in data hold mode, the "RISK" icon appears on the LCD, and you can use the UP and DOWN buttons to adjust the threshold. Pressing the SET button saves the alarm setting. If the “WET” icon appears on the LCD, you can use the UP and DOWN buttons to adjust the threshold. Pressing the SET button again saves the alarm setting.
If the moisture measurement is higher than the RISK alarm setting, the meter will beep once every 2 seconds. If the moisture measurement exceeds the WET alarm setting, it will beep four times every 1 second.
Note: The RISK value can be adjusted from 0 to 50 (default 30). The WET value can be adjusted from 50 to 100 (default 60).
Backlighting
Press the UP button to switch the backlighting on or off when the meter is in data hold mode. The display will be backlit with a series of white LEDs.
Moisture Table of Comparison
| Construction Material | Display (Unit) | Moisture Status |
| Gypsum | < 30 | Dry |
| 30 ~ 60 | Risk | |
| > 60 | Wet | |
| Cement | < 25 | Dry |
| 25 ~ 50 | Risk | |
| > 50 | Wet | |
| Wood | < 50 | Dry |
| 50 ~ 80 | Risk | |
| > 80 | Wet |
Important Notes
- If the ball head is in a corner, maintain a minimum distance of 8 to 10cm from the corner area.
- The ball head must be kept perpendicular to the measured material during measurement and pressed firmly against the surface, not slanted.
- For materials with a thickness of less than 20cm, consider potential impacts on readings.
- If "BAT" appears on the display, it indicates a low battery, and moisture values may be incorrect.
