5. Illuminance measuring
- In process of measuring illuminance, the sensitive mirror must be perpendicular to the
measured illuminating source to ensure accuracy of measured data..
- If distance between measured illuminating source and illuminometer, positions or different of
them, or the environment is different, then the measured data will be different; cause, the intensity
of light varies with change of distance, position, angle and environment. Since the intensity
of light will be varied with its distance, position, angle and surroundings to illuminometer,
measured date will be different accordingly.
- Make sure there is no scratch or dirt on sensitive mirror of luxometer, or the measured data
won't be accurate.
- When the illuminance exceeds the measuring range of the luxometer, "OL" sign will be
displayed.
- After completing measuring, cover the sensitive mirror with cap to avoid scratch on sensitive
mirror and keep it clean.
