Modulation Setup
Select the
Settings/Modulation
menu.
Before the MFA-7/14/21/28 can deliver meaningful measurement results, its dynamic range must be adjusted to the mea-
surement situation. This is done with the intensity adjustment (modulation).
Via the drop-down menu, it is possible to select whether the dynamic range adjustment (modulation) takes place for all
channels, for all activated channels, or for a single channel only.
The dynamic range is adjusted (modulation) in three successive steps in the
Settings/Modulation
menu.
Follow the instructions listed under
Step 1 (Autogain)
and click on the
Start Setup
button.
After this step has been completed, a green check mark appears, which indicates that it was successful.
i
All channels selected for modulation must be illuminated. For this purpose, it is advisable to select the brightest
possible lighting situation such that no underflow or overflow occurs in the receiving detectors. The actual light
color is not important, because only the dynamic range in the received brightness (Ix) is adjusted.
Switch the light source off and click on the
Start Step 2
button.
After this step has been completed, a green check mark appears, which indicates that it was successful.
i
In Step 2 (Dark Correction), a dark correction is carried out. None of the channels selected for adjustment may be
illuminated during this process.
Enter a percentage value, switch the light source on again and click on the
Start Step 3
button.
i
Because there are always fluctuations in the production of light sources or because you might not have the correct
light source with maximum brightness for the adjustment, you can set a control level in % for the receiver here. If,
for example, it is set to 80 %, the light source to be measured can still be 20 % brighter before overflow occurs in
the receiver.
After this final step has been completed, you can save the modulation setup either in the working memory using the
Save in RAM
button or in the MFA-7/14/21/28 controller using the
Save permanently
button. If you just want to save
it in the RAM, the settings will be lost when you restart the controller and the adjustment will have to be carried out again.
However, you can permanently save the settings under
Settings/Configuration
later.
