6.5.2.5. GAS LIST ENTRY FORMAT AND DEFINITIONS
The T802 analyzer keeps a list of available gas types. Each entry in this list is of
the following format.
[GAS TYPE],[RANGE],[GAS ID],[REPORTED]
WHERE:
GAS TYPE = The type of gas being reported (e.g. O2, CO2).
RANGE = The concentration range for this entry in the gas list. This feature
permits the user to select which concentration range will be used
for this gas list entry. The T802 analyzer has two ranges:
RANGE1 or LOW and RANGE2 or HIGH (See Section 5.4.1).
0 -
The HESSEN protocol to use whatever range is currently
active.
1 - The HESSEN protocol will always use RANGE1 for this gas list
entry
2 - The HESSEN protocol will always use RANGE2 for this gas list
entry
3 - Not applicable to the T802 analyzer.
GAS ID = An identification number assigned to a specific gas. In the case of
the T802 analyzer in its base configuration, there is only one gas
O2 , and its default GAS ID is 110. This ID number should not be
modified.
REPORT = States whether this list entry is to be reported or not reported when
ever this gas type or instrument is polled by the HESSEN network.
If the list entry is not to be reported this field will be blank.
The T802 analyzer is a single gas instrument that measures O2.
Thus the default gas list entry would be:
O2, 0, 110, REPORTED
No default gas list entry exists for CO2. If the optional CO2 senor is installed, the
following gas list entry should be added: CO2, 0, 111, REPORTED
These default settings cause the instrument to report the concentration value of
the currently active range. If you wish to have just concentration values stored
for a specific range, this list entry should be edited or additional entries should be
added (see Section 6.5.2.6).
EXAMPLE:
Changing the above O2 gas list entry to read O2, 2, 110, REPORTED while
RANGE2 (HIGH) range was active would cause only the last O2 reading to be
recorded.
