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 display range is the complete pressure range where the gauge gives an 
indication (measurement signal). The display range consists of underrange, 
measurement range and overrange. 
According to these definitions, 4 points are defined: 
 
1  Lowest informational measurement value 
2  Lowest precision measurement value 
3  Highest precision measurement value 
4  Highest informational measurement 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.
