6.1 પાવર ચાલુ/બંધ

• 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 એક માપન લેવું

1. મીટર પર પાવર.
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 એકમ પસંદગી

• 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 ડેટા હોલ્ડ

• 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.

Back. Back બેકલાઇટ

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