Overview
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA output,
that is, to define the relationship between mA Output Process Variable and the mA output
level.
Note
For transmitter software v5.0 and later, if you change LRV and URV from the factory default values,
and you later change mA Output Process Variable, LRV and URV will not reset to the default values. For
example, if you set mA Output Process Variable to Mass Flow Rate and change the LRV and URV, then you
set mA Output Process Variable to Density, and finally you change mA Output Process Variable back to Mass
Flow Rate, LRV and URV for Mass Flow Rate reset to the values that you configured. In earlier versions of
the transmitter software, LRV and URV reset to the factory default values.
