- Sensor Head: Located at the top, this is the light-sensitive component. Ensure it is clean and unobstructed for accurate readings.
- Illumination Display Area: Shows the current illuminance in LUX or FC.
- Color Temperature Display Area: Shows the current color temperature in Kelvin (K).
- Power Button (⑂): Turns the device on/off.
- HOLD/UNIT Button: Press once to hold the current reading. Press and hold to switch between LUX and FC units.
2. Taking Measurements
- Turn on the device by pressing the power button.
- Position the sensor head towards the light source you wish to measure. Ensure no shadows or obstructions are cast on the sensor.
- The device will automatically display the illuminance (LUX/FC) and color temperature (K) readings.
- To hold the current reading on the display, press the HOLD/UNIT button once. Press it again to release the hold and resume live readings.
- To switch between LUX and FC units, press and hold the HOLD/UNIT button until the unit changes on the display.
