Top Panel
The top panel contains the sample chamber in which the sample container is placed for analysis, or the
standard(s) for calibration.
The sample chamber should remain capped except when inserting or removing a sample. If left
uncapped, water vapor will adsorb on the inner surface of the chamber and the temperature becomes
unstable; either condition can affect analysis results. If water vapor accumulates in the chamber, the
pycnometer must be purged to remove it.
RS232 port Enables you to use a serial line for data transmission.
This port can also be used to attach an analytical balance for
automatic transmission of the sample mass. Refer to
Analyze , page 3-23 for details on transferring the mass value
to the analyzer.
RS-232 PIN ASSIGNMENT , page H-1 provides the pin
assignment for the RS232 port.
Power connector For connecting the AC/DC adapter cord, which provides
power to the pycnometer. The pycnometer power cord plugs
into the adapter.
Analysis module
connector For connecting an additional analysis module; you can attach
up to five additional analysis modules to the initial control/
analysis module. Each analysis module is equipped with
Analysis module input and output connectors.
Gas inlet port For connecting the analysis gas; helium is the recommended
gas. If you have multiple analysis modules attached, each
module contains a gas inlet port. Multiple gases can be
attached using the Multigas option (refer to
ORDERING
INFORMATION , page 6-1 .)
