6. Instrucións de funcionamento
6.1 Medición básica
After powering on, the device will immediately begin measuring illuminance. Point the light sensor towards the light source or area you wish to measure.
6.2 Unit Selection (LUX / FC)
Preme o Botón UNIT to toggle between LUX (lux) and FC (foot-candle) measurement units. The selected unit will be displayed on the LCD screen.
Figura 6.1: The meter's display showing measurements in FC (left) and LUX (right) units.
6.3 Función de retención de datos
Preme o Botón HOLD briefly to freeze the current reading on the display. Press it again to release the hold and resume live measurement.
6.4 MAX / MIN Display
Preme o Botón MAX/MIN to cycle through the maximum, minimum, and current readings recorded since the device was powered on or the function was reset. The display will indicate 'MAX' or 'MIN' accordingly.
6.5 Función de retroiluminación
Manteña premido o Botón UNIT for approximately 2 seconds to turn the LCD backlight on or off.
6.6 Measurement Range Multipliers
The meter automatically adjusts its measurement range. When 'X10' or 'X100' appears on the display, the displayed reading must be multiplied by that factor to obtain the actual illuminance value.
Figura 6.2: Explanation of how to interpret readings when 'X10' or 'X100' multipliers are active on the display.
- If 'X10' is displayed, multiply the reading by 10. For example, a display of 16.47 with 'X10' means 164.7 LUX.
- If 'X100' is displayed, multiply the reading by 100. For example, a display of 16.47 with 'X100' means 1647 LUX.
6.7 Bluetooth Connectivity and Data Logging
The device supports Bluetooth connectivity for real-time monitoring and data logging via a compatible smartphone application.
