Analog Output
The system will scale the PV from its LRV/URV (Lower Range Value / Upper Range Value) range
to the AO’s Zero/Full range. As the PV exceeds this range, the AO will continue linearly until it
reaches the AO URV (AO Under Range Value) or AO ORV (AO Over Range Value), where it
“flatlines.” At this point, the output is considered saturated, and will be limited to that value.
If the PV’s data quality goes BAD, or a system error is detected which should result in the
programmed fail response, the AO will respond as configured by either:
•
Fail High to 23.6 mA
•
Fail Low to 3.6 mA
•
Hold Last Value
•
Fail to a Preset Value, configurable between 3.6 and 23.6mA
Analog Output Trimming
AO Trimming increases the accuracy of your instrument by calibrating its analog output to the
device that is receiving the output. This ensures that the instruments are matched to each other.
Display (TDZ
3
only)
All dynamic and additional device variables in the transmitter can be selected for display. If none
are selected, then the unit will behave as though the PV is marked for display. A “screen” of data
includes the two main rows of characters on the display. Normally, a floating point value is shown
on the top with a text message on the bottom row. Some items require more than one screen to
be displayed. Each screen is shown for 2 seconds. If the value being displayed changes, it will
be updated while that screen is being shown.
