Terminology used for the movement of data
from the analyzer to the LSGAM application on
the PC.
Dual beam infrared absorption
Method of gas detection by measuring how
much infrared is absorbed by the target gas.
Event log
Used as an aid to monitoring the use of the
analyzer. It can also be used as a diagnostic
tool.
The event log can be viewed via Landtec
Systems Gas Analyzer Manager. It cannot be
viewed on the analyzer screen.
Exhaust port
The usual manner for the gas to exit the
analyzer is via the exhaust port located on the
top side of the analyzer. This port should have
an exhaust tube attached.
Exhaust tube
Clear plastic tubing used to expel gases from
the exhaust port.
Factory settings
Default settings preset at time of manufacture
or service.
Firmware
Firmware is the term by which the internal
analyzer software is known and is not accessible
by the client. This firmware is updated to the
latest version when the analyzer is returned to
the factory for servicing.
Flow measurement
Flow can be measured by either gas velocity
m/s or volume flow rate m
3
/hr. This
measurement of flow relates to the use of the
anemometer and not the internal flow
measurement technique.
Flow port
For the measurement of gas flow at the sample
point.
Gas channels
The gases that are analysed by the instrument.
Gas velocity
The positional rate of change of the gas.
Measured using the optional anemometer.
