The menu item “Sample rate” is displayed, if
you have selected a fixed sensitivity.
The integration time is set via the buttons

Pressing
on 10 ms setting switches to low sensitivity.
This reduces sensitivity by factor of 5.

Averaging
The UVpad E can calculate the irradiance from the moving average. Hereby are signal-to-noise
ratio, and thus measurement accuracy can be enhanced.
For integration times below 500 ms we recommend averaging over 16-32 measurements, while
for integration times over 500 ms smaller settings may be useful.
9.3.3
Effective Function*
Effective functions serve for the process-oriented measurement. This is often also called effect-
related or actinic measurement.
In that case, effective functions can be for example:
-
Absorption spectrums of photo initiators
-
Spectral sensitivity function
-
Filter function for instrument comparisons
In the Eff. function menu, the desired function can be selected using the
-key or
-key and
confirmed with the
-key.
Select „radiometric“, for traceable and inter-
nationally comparable measurements.
Select an effective function for a process-
oriented measurement and a targeted system
optimization. The international comparability
is not given.
