6.2 Te Whanganga

1. Te hiko i runga i te mita.
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 Whiringa Unit

• 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 Pupuri Raraunga

• Press the 'HOLD' button (often marked 'H') to freeze the current reading on the display.
• Pēhia anō te 'PŪ' hei tuku i te pānui ka hoki ki te ine ora.

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 Rama Whakamuri

• 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. Tiaki

7.1 Te horoi

• Horoia te mita casing me te ngohengohe, damp kakahu. Kaua e whakamahi i nga kai horoi me nga whakarewa.
• 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 Rokiroki

• Ki te kore e whakamahia mo te wa roa, tangohia nga pākahiko kia kore ai e pakaru.
• Store the meter in its protective pouch in a cool, dry place, away from direct sunlight and extreme temperatures.

7.3 Whakakapinga Pūhiko

• Ina puta te tohu pākahiko iti ki te mata, whakakapia ngā pākahiko e ai ki te whakaahuatanga i te Wāhanga 5.1.

8. Te Raru

• Kāore te mita e whakakā: Tirohia te tāutanga o te pākahiko, kia mōhio ai kei te hou tonu ngā pākahiko.
• Ko nga panui kore tika: Ensure the sensor is clean and unobstructed. Perform a ZERO calibration. Verify correct unit selection.
• He atarua, he korikori ranei te whakaaturanga: Whakakapihia nga pākahiko.
