Range Value
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 signal.
LRV is the value of mA Output Source represented by an output of 4 mA. URV is the value of mA Output
Source represented by an output of 20 mA. Between LRV and URV, the mA Output is linear with the process
variable. If the process variable drops below LRV or rises above URV, the transmitter posts an output
saturation alert.
Procedure
Set LRV and URV as desired.
Enter LRV and URV in the measurement units used for mA Output Source.
• Defaults: Specific to each process variable
• Range: Unlimited
Note
You can set URV below LRV. For example, you can set URV to 50 and LRV to 100. If you do this, the mA
Output will be inversely proportional to the value of mA Output Source.
Tip
For best performance:
• Set LRV ≥ LSL (lower sensor limit).
• Set URV ≤ USL (upper sensor limit).
• Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span).
