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 اختيار الوحدة

• 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 عقد البيانات

• 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 الإضاءة الخلفية

• 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. الصيانة

7.1 التنظيف

• امسح عداد Casing مع لينة، damp القماش. لا تستخدم المنظفات أو المذيبات الكاشطة.
• Keep the UV sensor clean and free from dust or debris to ensure accurate readings. Use a soft brush or compressed air if necessary.
