3.3 Contact Measurements
Move the slider switch to “cd/m²”.
Place the sensor flat on the surface to be meas-
ured. Select the desired measuring range using
the selector slider switch.
Notes
– Strong ambient light can influence the measure-
ment. This is particularly important when a glass
pane is sandwiched between the actual screen
surface and the sensor.
– Artificial light sources do not achieve full lumi-
nance until they have warmed up. It is therefore
advisable to switch on 15 min. earlier.
– The luminance of light sources depends on the
power supply i.e. check the voltage with a volt-
meter where necessary.
3.4 Overflow
If the measuring range is exceeded
the display merely shows a 1 on
the left, the other digits will be
blank. Move to the next higher
range.
Display Hold
Pressing the display hold button will “freeze” the
readout at that time. Pressing this button again will
release the hold and normal measurements can
be resumed.
