Scaling Low Engineering
Set the Low Engineering value for the module. The Low Engineering value must
not equal the High Engineering value. This is the value in engineering units that
corresponds with a signal value equal to the Low signal.
Valid values are in the range of -10,000,000…100,000,000. The default value
is 0.00.
Scaling Example
If you would like the module to tell you how full a tank is, you configure the
scaling to give you 0% when the tank is empty and 100% when the tank is full.
Suppose your sensor that measures the tank signals 4.5 mA when the tank is
empty and 17 mA when the tank is full. You would configure scaling like this:
