5. Instruccions de funcionament
5.1 Prendre una mesura
- Turn on the moisture meter.
- Select the appropriate material group if your device supports multiple settings (refer to the device interface for options).
- Place the sensor ball firmly against the surface of the material you wish to measure. Ensure full contact for accurate readings.
- The meter will display the moisture content. The pinless design allows for measurement depth of approximately 20-40mm below the surface.
5.2 Understanding Display Functions
- MANTENIR: Premeu el botó HOLD per congelar la lectura actual a la pantalla. Premeu-lo de nou per alliberar-la.
- MÀXIM / MÍN: Aquesta funció us permet view the maximum and minimum moisture readings recorded during a measurement session.
5.3 Interpreting Moisture Readings
The meter provides readings in digits. Use the following table as a general guide for interpreting moisture status in Gypsum and Cement. Note that these are indicative values and may vary based on specific material composition and environmental conditions.
| Material de construcció | Mostra de lectura | Estat d'humitat |
|---|---|---|
| Guix | <30 digits | Seca |
| 30 - 60 dígits | En risc | |
| > 60 dígits | Humit | |
| Ciment | <25 digits | Seca |
| 25 - 50 dígits | En risc | |
| 50 - 75 dígits | Humit | |
| > 75 dígits | All Wet |
5.4 Alarmes programables
The DT-128M allows you to set custom moisture alarm thresholds. When the measured moisture content exceeds the programmed level, the device will emit an audible alarm, indicating a potentially problematic moisture level. Refer to the device's on-screen menu or specific button combinations for setting these alarms.
6. Manteniment
6.1 Neteja
To ensure accurate readings and prolong the life of your meter, keep the sensor ball and the device body clean. Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing o components electrònics.
6.2 Substitució de la bateria
When the low battery indicator appears on the display, replace all three AAA batteries promptly. Refer to section 4.1 for battery installation instructions. Always use fresh batteries of the same type.
6.3 Emmagatzematge
When not in use for extended periods, remove the batteries to prevent leakage and store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case to prevent damage.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén | Bateries gastades o mal instal·lades | Comproveu la polaritat de la bateria; substituïu-la per piles AAA noves. |
| Lectures inexactes o inconsistents | Poor contact with surface; incorrect material setting; sensor dirty | Ensure full contact with the surface; verify correct material group selection; clean the sensor ball. |
| Alarm sounds unexpectedly | High moisture detected; alarm threshold set too low | Check the material for actual moisture; adjust the programmable alarm threshold if necessary. |
| La pantalla és tènue o il·legible | Low battery; backlight off | Replace batteries; activate backlight function. |
8. Consells d'usuari
- For best results, take multiple readings across the surface of the material to get a comprehensive understanding of moisture distribution.
- Always ensure the sensor ball is in full contact with the surface being measured. Gaps can lead to inaccurate readings.
- Be aware that surface coatings or very dense materials might affect the penetration depth and accuracy of pinless meters.
- Keep the meter away from strong electromagnetic fields, which can interfere with its operation.
