The “Basic Setup” menu allows the user to modify the
engineering units, damping value, whether the Local
Display scrolls or is fixed on a particular process variable
(unit, % or mA). The option to change the transmitters
probe length is also available but is not recommended.
Note: probe length is NOT the measuring range; it is the
overall length of the transmitter – including its deadbands.
The parameters shown in bold can be edited by the user.
Changing “PV URV” from 14.00” to 12.00” would scale the 4-to-
20 mA output of the instrument (
without level simulation). Level
Offset is a digital value added to both the LRV and URV but does
not affect the mA output only the digital number displayed. Rate
of Change can be used to ignore spontaneous noise that can
occur in applications that are not wired properly.
