5. Instrucciones de funcionamiento
5.1 Tomando una Medición:
The ZKH Pinless Moisture Meter uses a spherical probe for non-destructive measurements. To take a reading:
- Asegúrese de que el medidor esté encendido y calibrado.
- Place the spherical probe flat against the surface of the material you wish to measure. Ensure the probe is perpendicular to the surface.
- The meter will display the moisture content reading on the LCD screen.
- For consistent results, avoid moving the meter during measurement.

- Current Measurement Reading: The primary moisture value.
- HOLD ALM SET HI LOW: Indicators for data hold, alarm settings, and high/low moisture alerts.
- MAX MIN AVG CM: Displays maximum, minimum, and average readings.
- Dry/Wet Indicator: A graphical bar indicating relative dryness or wetness.
- Indicación de batería baja: Icon appears when batteries need replacement.
5.3 Moisture Alert System:
The meter can be set to alert you when moisture levels exceed a predefined threshold. Refer to the device's on-screen menu (accessed via the SET button) to configure alarm levels. When the moisture level surpasses the set limit, an audible alarm and/or visual indicator will activate.
5.4 Data Hold Function:
Press the "M" button briefly during measurement to hold the current reading on the display. Press it again to release the hold and resume live measurement.
5.5 Automatic Power-Off:
To conserve battery life, the meter will automatically power off after approximately 3 minutes of inactivity.
5.6 Important Measurement Considerations:
For reliable moisture detection, ensure the measurement area is free from obstructions.
