9.2.2 Start manual dark measurement
For manual darkness measurement, select the menu item "dark+radiometric" under Settings,
Measurement mode. If your UVpad E is equipped with several effective functions, manual
dark measurement may be available for further effective functions.
Note:
Manual darkness measurement is only active in the sensitivity mode "fixed".
Therefore, set a fixed integration time!
If the darkness measurement is not done for the integration time, the UVpad
E will not display any values. In this case the irradiance and dose values are
displayed with "-".
Manual darkness measurement is important if the irradiance at the end of the
short-wave measuring range (e. g. 240 nm) is not "zero", otherwise the meas-
ured values are too low.
