The Information Data object defines the input process data.
The "measurement range" is the range between minimum and maximum pressure,
where the reading of the gauge is within the specified measurement uncertainty
limits.
The "valid measurement information range" (display range) is the complete
pressure range where the gauge gives an indication (measurement signal). The
valid measurement information range (display range) consists of underrange,
measurement range and overrange.
According to these definitions, 4 points are defined:
Lowest informational measurement value
Lowest precision measurement value
Highest precision measurement value
Highest informational measurement value
0x02 REAL x RO Highest Informational
0x03 REAL x RO Highest Precision
0x04 REAL x RO Lowest Precision
0x05 REAL x RO Lowest Informational
Accumulated Zero Offset: An amount added prior to Gain to derive Value. Result of
Zero Adjust Command (accumulated value).
Highest Informational Measurement Value: Highest value that the gauge can
measure without a specified accuracy.
Highest Precision Measurement Value: Highest valid value at which the gauge is
specified with an accuracy value. Above that value, the parameter Reading Valid is
set to invalid.
Lowest Precision Measurement Value: Lowest valid value at which the gauge is
specified with an accuracy value. Below that value, the parameter Reading Valid is
set to invalid.
