OPERATING INSTRUCTIONS - LIGHT INTENSITY METER BF05
Moving the appliance from a cold to a warm envi-
ronment (and vice versa) can lead to the formation
of condensation on the measuring circuitry of the
appliance. This physical effect, which cannot be
prevented by structural means for any measuring
instrument, leads to false measurement values.
Depending on the temperature difference, the appli-
ance requires an 'acclimatisation time' of approx.
15 - 30 minutes before the measuring procedure
can be resumed.
