pointer
28
We recommend using the laser alignment tool (available as an
accessory) for rough coaxial alignment of the opposite purging
flanges. The laser alignment tool consists of a laser pointer and a
focusing screen.
Fine alignment of the purging flange takes place once all the de-
vices have been electrically connected using the instrument soft-
ware.
The clamps for fastening the laser alignment tool must only be
used to fasten the laser pointer and the focusing screen. It is
prohibited to use these clamps for mounting the transmitter unit
and the receiver unit. The clamps are labeled with a correspond-
ing note.
The laser alignment tool falls into laser protection class 3A.
Step Procedure
1 Install the laser pointer on the purging flange to which the trans-
mitter unit should be mounted, and the focusing screen on the
purging flange to which the receiver unit should be mounted. Per-
form the rough alignment.
2 Install the laser pointer on the purging flange to which the receiver
unit should be mounted, and the focusing screen on the purging
flange to which the transmitter unit should be mounted. Perform
the rough alignment.
3 Install the laser pointer on the purging flange to which the trans-
mitter unit should be mounted, and the focusing screen on the
purging flange to which the receiver unit should be mounted. Per-
form the rough alignment.
