Final Alignment Procedure
Final alignment of Transmitter or Receiver units can be performed using just the alignment
telescope and the precision adjustment mechanisms built into the mounting brackets.
The primary objective of the final alignment procedure is to align each unit such that the crosshairs
on the alignment telescope is in the centre of the lens-window of the opposing unit as illustrated
below:
Notes :

Unlike NDIR OPGDs, Senscient ELDS 1000 / 2000 Series OPGDs are not critically sensitive to
alignment.

A small improvement in alignment can be achieved by performing alignment adjustments whilst
monitoring the received signal levels using SITE running on an industrial computer. However,
for ELDS 1000 / 2000 Series OPGDs these small improvements are not important or
necessary. ELDS OPGD systems aligned by the correct use of the alignment telescope will
perform to full specification without further alignment tuning.
