Windows error message: "The device driver software was not installed correctly"
When connecting the wavefront sensor head to the PC for the first time, Windows may show
this erroneous error message.
In most cases, this error message can be ignored and you can proceed to use the WFS. In
case you can not access the WFS through the software, please see the section
Troubleshoot-
ing in the full manual, downloaded from the software website.

Ø
Perhaps the measurement has been stopped. Check the status window at the bottom of
the Wavefront Sensor GUI. If there is a message like this
just start the measurement again by clicking the symbol in the toolbar or simply press
'F2'.
Ø
If the measurement isn't stopped, the reason may be that the camera is set to a high num-
ber of averages - it will take a long time to get a result in this case.
Go to the Camera Settings panel and select a smaller number of aver-
ages.
Ø
The trigger functionality was activated but no trigger signal is applied. Check the 'Hard-
ware Trigger' control within the
Camera Settings . See the section Trigger Input for
trigger signal input configuration.
