Measurement 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 in place 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.
