The Extech UV505 features a UV sensor at the top, a large LCD display in the center, and several control buttons below the display. The main power button is typically orange and centrally located. Other buttons include ZERO, UNIT, and a backlight button (often indicated by a light bulb icon) and a HOLD button (indicated by 'H'). The battery compartment is located on the rear of the device.

5. Setup

5.1 Installazzjoni tal-batterija

1. Sib il-kompartiment tal-batterija fuq wara tal-miter.
2. Press the release button (if present) and slide open the battery cover.
3. Daħħal żewġ batteriji AAA, waqt li tiżgura l-polarità korretta (+ u -).
4. Replace the battery cover and ensure it clicks securely into place.

6. Istruzzjonijiet Operattivi

6.1 Power On/Off

• To power on the meter, press the orange power button.
• To power off the meter, press and hold the orange power button until the display turns off. The meter also features an auto power-off function after a period of inactivity.

6.2 Teħid ta 'Kejl

1. Qawwa fuq il-meter.
2. Point the UV sensor directly towards the UV light source you wish to measure.
3. Read the UV intensity value displayed on the LCD screen.

6.3 Zero Function

• To ensure accurate readings, especially in low UV environments, use the ZERO function.
• Cover the UV sensor completely to block all light.
• Press the 'ZERO' button. The display should show '0' or a very small value.

6.4 Għażla ta' Unità

• Press the 'UNIT' button to cycle through available measurement units, typically µW/cm² (microwatts per square centimeter) and mW/cm² (milliwatts per square centimeter).

6.5 Żamma tad-Data

• Press the 'HOLD' button (often marked 'H') to freeze the current reading on the display.
• Press 'HOLD' again to release the reading and return to live measurement.

6.6 Min/Max Function

• While measuring, press the 'MIN/MAX' button (or similar, depending on model) to display the minimum or maximum UV intensity recorded since the function was activated.
• Cycle through Min, Max, and current readings by pressing the button repeatedly.
• To clear Min/Max memory, typically press and hold the 'MIN/MAX' button, or power cycle the device.

6.7 Dawl ta 'wara

• Press the backlight button (light bulb icon) to illuminate the LCD display for better visibility in low-light conditions.
• Press it again to turn off the backlight.

7. Manutenzjoni

7.1 Tindif

• Imsaħ il-marka tal-miterasing b'artab, damp drapp. Tużax tindif jew solventi li joborxu.
• Keep the UV sensor clean and free from dust or debris to ensure accurate readings. Use a soft brush or compressed air if necessary.

7.2 Ħażna

• Meta ma tkunx qed tużahom għal perjodi twal, neħħi l-batteriji biex tevita t-tnixxija.
• Store the meter in its protective pouch in a cool, dry place, away from direct sunlight and extreme temperatures.

7.3 Sostituzzjoni tal-batterija

• Meta jidher l-indikatur ta’ batterija baxxa fuq id-displej, ibdel il-batteriji kif deskritt fit-Taqsima 5.1.

8 Issolvi l-problemi

• Il-miter ma jixgħelx: Iċċekkja l-installazzjoni tal-batterija u kun żgur li l-batteriji huma friski.
• Qari mhux preċiż: Ensure the sensor is clean and unobstructed. Perform a ZERO calibration. Verify correct unit selection.
• Il-wiri huwa dgħajjef jew itteptip: Ibdel il-batteriji.
