A prominent LCD readout displays a digital calculation and complementary analogue bar graph for quick, reliable assessments.

Measurement Procedure

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.
