CONF - Change I / O - UNITS option
Using the F1 key to select the procedure CHaNGe I/O the following
display will appear showing the current units used for defining the
operating range of the transmitter, i.e. the LRV and the URV.
Pressing the F3 key (CHNG) the display changes as shown.
The current units are en closed within square brachets: using F1 or F2 you
can select, in turn, all the units, available in the Communicator, for the type
of the connected transmitter. When the correct choice has been done
press the ENTeR key to send the new unit to the transmitter: the blinking
T in the right top corner of the display signals that the communication is
in course and after some seconds the previous display appears with the
selected new units.
Note that the change of the units does not change the value of the
calibration of the transmitter : the LRV and URV will be automatically
expressed in the new unit. As an example if you change from mbar to bar
and your URV was 70 mbar the new value of URV will be 0.0700.
Note : the measures in inches and mm. of H2O can be done using
different temperature reference. Usually in the United States the
measures are referenced at 20
°
C ( 68
°
F ) whereas in Europe the usual
reference is 4
°
C ( 39.2
°
F ). To avoid errors in calibration and measurement
the units should be expressed correctly: the display shows, in the units
option and in Review, the units with the relevant temperature reference,
as an example in. H2O@20DegC. The units at 4
°
C are only available
from 600T Series transmitter revision 5.2 onwards and in the 600T EN
Series Transmitter.
See APPENDIX "B" for the list of allowed Primary Variable Units.
For 600T EN transmitters three other options are available under
CONF - Change I/O:
CONF - Change I/O - SENSOR TEMPERATURE UNITS option
Using this option, it is possible to select the unit for the sensor temperature
value.
In the APPENDIX "B" there is a list of units available for the temperature
units selection.
CONF - Change I/O - STATIC PRESSURE UNITS option
The available units for static pressure indication are MPa, psi and bar.
You can select your preferred unit using the key F3 (CHNG) in the
displayed menu.
CONF - Change I/O - L. TAG. option
With this option it is possible to add a longer tag for function or instrument
identification.
Select Key F3 (CHNG) and use the function keys from F1 to F3 to define
the long tag.
Press the key F4 (ENTR) to accept the long tag modification.
