5. Opstelling
5.1 Battery installasie
- Vind die batteryklepdeksel aan die agterkant van die toestel.
- Skuif of knip die deksel los om dit oop te maak.
- Plaas twee 1.5V AAA-batterye in en maak seker dat die polariteit (+/-) korrek is soos aangedui in die kompartement.
- Plaas die batterykompartement se deksel veilig terug.
5.2 Aan-/afskakel
- Om aan te skakel: Druk die Kragknoppie (). The LCD screen will illuminate.
- Om af te skakel: Druk die Kragknoppie again. The device also features an automatic power-off function to conserve battery life.
6. Bedryfsinstruksies
6.1 Basiese Meting
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)
Druk die UNIT -knoppie to toggle between LUX (lux) and FC (foot-candle) measurement units. The selected unit will be displayed on the LCD screen.
Figuur 6.1: The meter's display showing measurements in FC (left) and LUX (right) units.
6.3 Data Vashou Funksie
Druk die HOLD-knoppie 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
Druk die MAX/MIN-knoppie 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 Agtergrondbeligtingsfunksie
Druk en hou die UNIT -knoppie 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.
Figuur 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.
Figuur 6.3: The Lux Meter connected to a smartphone via Bluetooth, displaying real-time data and a historical graph.
- Aktiveer Bluetooth: Druk en hou die HOLD-knoppie for approximately 2 seconds. A Bluetooth icon will appear on the meter's display.
- Laai die app af: Download the official Landtek application from your smartphone's app store.
- Koppel: Open the app on your smartphone and follow the instructions to pair with the MILA48500 device. The Bluetooth range is up to 10 meters.

7. Onderhoud
- Skoonmaak: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the light sensor is kept clean and free of dust.
- Berging: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries.
