NOTE
Notethatthetotalizationmightbecountedduetotheinuenceoftheoutputuctuationnear0%
output if a small low-cut value is set.
Inparticular,ifthevalueoftheowratespan,dampingtimeconstantorconductivityislow,the
totalizationiseasilycountedwhentheowrateiszero.Insuchacase,increasetheowrate
span, damping time constant, or low-cut value.
NOTE
If the output process value to be output is changed, it is necessary to specify the low-cut value
again.
5.1.8 Sensor’s Nominal Size Setting
To combine the remote transmitter with other remote sensor, the nominal size of the remote
sensor must be set.
Thesettingcanbeconguredwiththefollowingparameters.
