5.1 Главна единица

• LCD дисплеј: Shows measurement readings, units (Lux/Fc), and function indicators (MAX, MIN, HOLD, AUTO, RANGE).
• Контролни копчиња:
• POWER (Red button): Го вклучува или исклучува мерачот.
• МОД: Switches between Lux and Fc units.
• ГАРАНЦИЈА: Toggles between automatic and manual measurement ranges.
• ДРOLDАЈ: Го замрзнува тековното отчитување на екранот.
• MAX/MIN: Displays the maximum or minimum recorded value.
• REC: Activates data recording mode.

5.2 Photoreceptor Sensor

The sensor contains a photodiode with an additional filter, designed to meet CIE Photopic Spectral Response standards. It is connected to the main unit via a coiled cable that can extend up to 1300mm (51.18 inches) for flexible measurement positioning.
