Conditions: Sheet edge in optimal object position, fluctuation in read direction < ± 100 mm, constant
ambient temperature

The resolution of the analog outputs can influence the accuracy. The longer the measurement field width,
the lar
ger the influence.

In materials with high transmission, the temperature difference between the operating temperature and
the t
emperature during teach-in must be less than ± 15 K.
