4.6 Installation and connection
of a reference analyzer
The SGA 003 is designed to facilitate the mounting of a reference instrument.
A foldout console (20) is permanently attached to the SGA 003. A second dew point analyzer
from the “Hygrovision” series can be easily mounted on this console as a reference
instrument (see Appendix E).
Pull the handle (25) to bring the console (20) into the working position. Release the locking
device (26) and bring the mounting plate for attaching the reference instrument into a
horizontal position.
Hygrovision series analyzers have a threaded hole in their housings that matches the
mounting bolt set into the horizontal plate of the foldout console.
To affix the reference analyzer to the SGA, first screw the mounting bolt in the console plate
(27) into the threaded hole by turning clockwise. Then lock the analyzer in place by means of
the locking device (26).
Connect the measurement chamber of the reference unit to the control outlets using high-
pressure hoses.
Alternately, if this process is taking place under supervision, the outflow from the reference
instrument may be connected to a flexible low-pressure hose when taking control
measurements.
Fill the measurement chamber of the analyzer by means of the shut-off valve (7). Control the
outflow by operating the valve on the SGA unit (19).
Warning!
A high-pressure hose MUST be used for connecting the reference module
outflow to the SGA unit when measurements / control measurements are
carried out that are not supervised.
