Output
None
Floating point
Same as ZEROGAS
ppm
The value of the zero gas for the current range.
Used to show the current range's zero gas on menus, rather than the entire array of
span gases as would be shown by ZEROGAS. The analyzer copies the value of the
appropriate element of ZEROGAS into this variable whenever CRANGE is changed.

CRANGE
Output
None
Floating point
Same as ZERO
ppm
The value of the zero factor for the current range.
Used to show the current range's zero factor on menus, rather than the entire array
of zero factors as would be shown by ZERO. The analyzer copies the value of the
appropriate element of ZERO into this variable whenever CRANGE is changed.

DATA_INDEX
2-element integer array
Element 1: 0 - 96; element 2: 0 - 59, or up to 65535
None
Index into the locally stored data communicated in DATA_P0INT
The two elements have alternative meanings: if the second element has a value less
than or equal to 59, the second element refers to the time in minutes, and the first to
the time in hours - the time referring to the desired data point. If the value of the
second element is greater than 59, the first element then is taken to refer to the
index of the data point.
