CHAPTER 3
INSTALLATION
This chapter provides you with information intended to help you with
installing this product.
Preparing a Foundation
When choosing an installation site it is recommended to use a wide open
place where there are no tall trees, overhead lines, or antennas that could
bend or move to the ceilometer measurement path. If the CL31 is to be
installed in the proximity of radars or other powerful radio transmitters, it
is recommended to position the measurement unit door away from such
sources.
The standard foundation for the CL31 ground installation is a concrete
foundation. The recommended minimum dimensions suggested are
presented in Figure 4 on page 24. Mounting screws and bolts are
included in the delivery.
NOTE
In case CL31 replaces another ceilometer (CT25K, CT12K, LD40,
LD25, or LD12) the existing foundation and foundation screws can be
used.
