3.2 Safe-keeping
For long service life of Digi-Derm, observe the following maintenance
points:
• Keep the Digi-Derm clean and avoid moisture in the storage loca-
tion.
• Do not apply excessive force or shocks to the Digi-Derm.
• Turn the Digi-Derm OFF after use.
• Remove the batteries from the Digi-Derm when the Digi-Derm is
to be left unused for a long period.
• Avoid rubbing or excessive pressing of the measuring face of the
probe to prevent scratches or deformation. Wear on the measuring
face degrades measuring accuracy. Check the accuracy of your
Digi-Derm in the following manner: 1) prepare two calibration
films of different thickness (e.g.: 50µm and 100µm); 2) calibra-
tion the Digi-Derm on the provided reference specimen with one
calibration film (e.g.: 100µm); and 3) make sure that the measure-
ments of the other film (e.g.: 50µm) are as accurate as laid out in
"Specification".
