3.2 Engegada/apagada
- Per engegar: premeu i manteniu premut el botó Botó d'encesa (
) located below the screen. - Per apagar: premeu i manteniu premut el botó Botó d'encesa again. The device will also automatically power off after 15 minutes of inactivity to conserve battery.
4. Instruccions de funcionament
4.1 Funcions dels botons
- Botó d'engegada (): Press and hold to power on/off.
- Botó SEL: Short press to switch between Electric Field (E-field) and Magnetic Field (H-field) measurement modes.
- Botó AVG/MAX: Short press to cycle through current value, maximum value (MAX), and average value (AVG) display.
- Botó HOLD: Short press to freeze the current reading on the display. Press again to release.
- Botó RF: Short press to enter Radiofrequency (RF) measurement mode. Press again to exit RF mode and return to EF/MF measurement.
- Botó de silenci (Bell icon): Short press to toggle the audible alarm on or off.
4.2 Measurement Modes and Display
The meter's display shows real-time readings, an analog bar, and environmental data. The analog bar changes color to indicate radiation intensity:
- Verd: Low radiation level.
- groc: Moderate radiation level.
- Vermell: High radiation level, indicating potential concern.

4.2.1 Electric Field (EF) Measurement
In EF mode, the meter measures electric field strength in V/m. Press the SEL button until 'E-field' is indicated on the display. Common sources include power lines, electrical appliances, and wiring.
4.2.2 Magnetic Field (MF) Measurement
In MF mode, the meter measures magnetic field strength in mG or µT. Press the SEL button until 'H-field' is indicated. You can switch between mG and µT units. Common sources include motors, transformers, and high-current devices.
4.2.3 Radiofrequency (RF) Measurement
In RF mode, the meter measures radiofrequency power density in µW/cm². Press the RF button to enter this mode. The meter can detect frequencies from 30 MHz to 8 GHz. Common sources include Wi-Fi routers, mobile phones, cell towers, and microwave ovens.

4.2.4 Mesura de temperatura i humitat
The meter continuously displays ambient temperature in °C or °F and relative humidity in %. Use the appropriate button (refer to the full manual for specific button if not SEL) to switch between Celsius and Fahrenheit.
4.3 Funció d'alarma
When the measured radiation value exceeds the safety threshold, the meter will activate both an audible alarm (beeping sound) and a visual alarm (screen flashing, analog bar turning red). This alerts you to potentially high radiation areas.
- To mute the audible alarm: Press the Botó de silenci (bell icon). The visual alarm will remain active.
- To unmute: Press the Botó de silenci de nou.

4.4 Analog Digital Comparison Table
The following table provides a general guide for interpreting the analog bar display and corresponding digital values for different radiation types. These are indicative thresholds and may vary based on specific regulations or personal sensitivity.
| Unit Analog Display | RF (µW/cm²) | EF (V/m) | MF (mG) | MF (µT) |
|---|---|---|---|---|
| Verd (baix) | 0.0 ~ 9.9 | 0 ~ 9 | 0.0 ~ 0.9 | 0.00 ~ 0.09 |
| Yellow (Moderate) | 10 ~ 39.9 | 10 ~ 399 | 1.0 ~ 39.9 | 0.10 ~ 3.99 |
| Vermell (alt) | 40 ~ 9999 | 400 ~ 999 | 40.0 ~ 199.9 | 4.00 ~ 19.99 |
