TRANSMITTER D***
PARAMETERS
(THE 3102 AND 3105)
NOTE:
For relevant menu structures, refer to Appendix D or Appendix E, whichever
is appropriate for your HART Master Device.
The 'D' prefixed parameters (e.g. D900) monitor the transmitter operation.
Parameters listed here are in numerical order.
D900 (Xmtr PV)
D900 Description
This displays the live Process Value (or PV) that drives the 4–20 mA output of
the transmitter.
The factory default is for the PV to be a liquid level measurement in meters,
feet, or inches. However, it can be another measurement e.g. volume of liquid
content, if the transmitter has been programmed to calculate it.
In HART terminology, PV is the Primary Variable.
NOTE:
Display (Reported) units for PV are set by P012 – see page F-12.
D901 (Level, SV)
D901 Description
This displays the live liquid level measured by the transmitter. In HART
terminology, SV is the Secondary Variable.
NOTE:
Units are metres, feet, or inches, depending on the Base Units selected -
see “Parameter: BASE UNITS” on page F-2.
D902 (Distance, TV)
D902 Description
This displays the live distance-to-surface measured by the transmitter. In
HART terminology, TV is the Tertiary Variable.
NOTE:
Units are meters, feet or inches, depending on the Base Units selected –
see “Parameter: BASE UNITS” on page F-2.
D903 (Temperature, FV)
D903 Description
This displays the live ambient temperature measured by the transmitter. In
HART terminology, FV is the Fourth Variable.
NOTE:
Units are
°
C or
°
F, depending on the Base Units selected –
see “Parameter: BASE UNITS” on page F-2.
D905
(% of Current Output)
D905 Description
This displays the percentage of the Current Output in use.
The calculation is based on Upper and Lower Range values (P015 and P016)
whereby 0% represents 4 mA and 100% represents 20 mA.
