•
Temperature : Current measured (live) wet temperature of the gas
sample in selected engineering units.
•
Temperature Unit : Designates the display units for the measured
cell temperature and for dew point calculations.
•
Update RATA : When set to ‘1,’ stores the latest proposed RATA
multiplier and offset values in the RATA Multiplier and RATA Offset
parameters, respectively.
•
user ConvFactor 08 : Sets a custom conversion factor when the
parameter Concentration Unit = 8 (user EU Tag Part 1 and 2) and this
value is greater than 0.0. The default conversion factor is used when
it is equal to 0.0.
•
user EU Tag Part 1 : Sets a custom engineering unit tag name for
the beginning four ASCII characters. For example: A is ASCII hex
value 41, so AAAA would be 41414141, which would be
1,094,795,585 in decimal format. Refer to Table 3–4 on page 3–28.
•
user EU Tag Part 2 : Sets a custom engineering unit tag name for
the last four ASCII characters. For example: A is ASCII hex value 41,
so AAAA would be 41414141, which would be 1,094,795,585 in
decimal format. Refer to Table 3–4 on page 3–28.
To find the hexidecimal value in Table 3–4 on page 3–28, first locate the
character needed in the table and trace to the reference number in the row (c)
at the top of the table, then use the row to the left (r) to create the value (cr).
For example, locate the ‘A’ in the table. The ‘A’ corresponds with the value (4)
in the row at the top of the table. Next, follow the row in which ‘A’ is present to
the value at the left of the table (1). Combined, these create the hexadecimal
value of 41.
