The Extech LT300 Light Meter has a Digital and Analogue display of light in Lux or Foot-candles.
The LT300 Light Meter measures up to 40,000 Fc (or 400,000 Lux) utilising a remote light sensor connected via 12 in. coiled cable (expandable to 24 in.).
A prominent LCD readout displays a digital calculation and complementary analogue bar graph for quick, reliable assessments.

Measurement Procedure
1. Remove the protective cap from the sensor so that the white domed light sensor is exposed to the light. For overhead lighting, the sensor can be placed on a desk or table top. A tripod
mount and a tilt stand are located on the rear of the meter for convenience.
2. The display will indicate the light level in Fc or Lux.
3. Press the RANGE button to select the range that provides the maximum resolution. If the ‘OL’ appears the light measurement is out of range. Select another range using the RANGE button.
4. Press the backlight button to illuminate the LCD display if needed.
