Description
The most recent span value for the temperature transducer,
obtained during a T-Span calibration. The value is normally
very close to 1.0000 and is recalculated on each Temperature
Span Calibration.
Default = 1.0000
The previous value of item 038, updated on each Temperature
Span Calibration.
Default = 1.0000
The previous value of item 039, updated on each Temperature
Span Calibration.
Default = 1.0000
The configurable spread or difference (expressed in percent of
full-scale of the temperature range, i.e. -40.00 to +170.00 F or
210 degrees) required between TZERO and TCAL calibration
points.
Default = 10.0000
The configurable, maximum allowable change (expressed in
percent of full scale of temperature range) to TZERO and
TCAL calibration points.
Default = 2.0000
Total correction factor calculated at the most recent wake-up
and used as a multiplier to convert uncorrected volume to
corrected volume. It is the product of the values at Items 044,
045, 046 and 047, i.e. values at: 44 x 45 x 46 x (47)
Default = 1.0000
Pressure correction factor calculated at the most recent wake-
up using Boyle's Law for values at items 008, 013, and 014
when item 109 is set for LIVE. Items 044 and 008 may be
fixed factored to any reasonable value, by the user, if item 109
is set for FIXED.
Default = 1.0000
Temperature correction factor calculated at the most recent
wake-up using Charles' Law for values at items 026 and 034
when item 111 is set for LIVE. Items 045 and 026 may be
fixed factored to any reasonable value, by the user, if item 111
is set for FIXED.
Default = 1.0000
