12 Classification of the measurement results
PCE have provided the following table to be used as a guide when using the light intensity meter in
different environments. The table shows the standard settings to be used when using the light intensity
meter indoors. When using outdoors, considerably higher readings are to be expected (e.g. 30.000 lux or
100.000 lux in sunlight). These values are only approximate values and PCE cannot accept any liability
for their accuracy.
