3. Parameter settings before measurement
3.1
3.1.1 Setting the minimum: 0%
- Select the spectral band by turning the filter set (NF, IR, R, G, B)
- Put a piece of matt black 160g/m2 Canson paper under the radiation meter that is switched
on (refer to the zero setting image)
- Put your light source into place and switch it on.

3.1.2 Setting the maximum: 100%
ENGLISH
Calibrating the radiation meter
Keep the Min button pressed for a
few seconds to obtain the 0%
display (within 10%).
Keep the previously chosen spectral band.
Hold the matt black Canson paper in place.
The source must not move from the previous position.
Place the substance to be studied on 160 g/m
radiation meter, the substance must be placed in a plane parallel to the radiation meter.
Cover the target with a sheet of 180 g/m
Canson paper
Keep the « max » button pressed for about 2 seconds until
the value of about 100% appears.
3 cases can arise:
- Case No.1:
The displayed value is close to 100% (it can vary by plus or minus 8% depending on the
stability of the lighting), the setting is terminated for the studied spectral band.
- Case No. 2:

then the maximum setting must be made again.
