Purpose and function This instrument provides quick illuminance readings in Lux or footcandles (Fc). It is designed for simple, reliable light level measurement in various environments. Key benefits Flexible measurement units: switch between Lux and Fc to match your preferred standard. Multiple reading modes: normal, max, and min allow you to capture steady or peak/lowest light conditions. Protective cap helps shield the sensor when not in use, prolonging sensor life. Straightforward operation: power on, select unit, select mode, then measure with the sensor aimed at the light source. Clear, direct readings by properly orienting the sensor toward the light for accurate results. How to use 1) Remove the protective cap from the unit. 2) Power on the instrument. 3) Select the measurement unit (Lux or Fc) and choose the desired mode (normal, max, or min). 4) Hold the sensor so it faces the light source and read the result. Important attributes Function: illuminance measurement in two commonly used units Modes: normal for standard readings, max to capture peak light, min to capture the lowest light level Sensor orientation: measuring accuracy depends on the sensor facing the light source Build feature: protective cap to protect the sensor when not in use Use scenarios Interior lighting design and energy efficiency: verify room illumination levels to meet design goals or safety standards. Photography and videography: calibrate light levels for consistent exposure and scene lighting. Horticulture and plant growth: monitor grow light intensity to ensure plants receive appropriate light levels for healthy growth.
