6.7.2.5. HESSEN PROTOCOL GAS LIST ENTRY FORMAT AND DEFINITIONS
The T200 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 to be reported (e.g. NO
x
, NO and NO
2
etc.).
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 T200 analyzer has two ranges:
RANGE1
or LOW &
RANGE2
or HIGH (see Section 5.4).

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 T200 analyzer.
GAS ID
An identification number assigned to a specific gas. The T200 analyzer
is a multiple gas instrument that measures NO
x
, NO and NO
2
. Their ID
numbers are as follows:
NO
x
211
NO 212
NO
2
213
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. It’s default gas list
consists of only reads:
NOX, 0, 211, REPORTED
NO, 0, 212, REPORTED
NO2, 0, 213, REPORTED
These default settings cause the instrument to report the concentration value of the
currently active range. If you wish to have just concentration value stored for a specific
range, this list entry should be edited or additional entries should be added to the list.
EXAMPLE: Changing the above NO
x
gas list entry to read:
NOX, 2, 211, REPORTED
Would only record the last NO
x
reading that occurred while RANGE2 (HIGH) range
was active.
