Measurement Considerations and User Tips
For maximum accuracy allow the light being measured to fall directly on the sensor as
perpendicular as possible with a minimal angle of incidence.
When the meter is not in use, please keep the protective cap over the light sensor. This will
prolong the life of the sensor.
When the meter is to be stored for long periods, please remove the batteries and store them
separately. Batteries can leak and cause damage to the meter’s components.
Avoid areas of high temperature and humidity when using this instrument.
