Setting the Display
The TDY has numerous settings for its display, all
of which are controlled using the “Input Range and
Setup Options” box. You can set the customizable
display to display the input, output, or toggle between
the two every two seconds. The display will even
scale to display any type of engineering units you
desire.
Input, Output, and Toggle
The pull-down menu shown below is used to adjust
what the TDY displays. There are three settings:
“Input”, which causes the TDY to display the input
it is receiving, “Output”, which causes the TDY to
display the 4-20mA output it is emitting, and “Toggle”,
which causes the TDY to switch between displaying
Input to Output every two seconds. To switch
between these, simply click on the pull-down menu,
select the appropriate function, and program the
transmitter as described on page 9, starting with step
3.
Figure 7. The pull-down menu lets you select what the TDY displays.
Display Zero & Display Full
The display zero and display full show what values will
actually be displayed. If the pull-down menu in Figure
7 and the radio button on Figure 8 both have “Input”
selected, then Display Zero will match Input Zero
and Display Full will match Input Full. The Display
columns then cannot be changed except by changing
the display value.

input display to a scaleble display of any engineering unit type.
Scaling the Display
The TDY can scale its display. This feature is useful
when you need to limit, expand, or manipulate the
numbers the TDY displays. Doing this also gives you
the option of changing the engineering units
being displayed to any engineering unit type.
Scaling the input display is a simple procedure. First,
click “Scale” on the radio button in Figure 8. (Note
that if you have the pull-down menu in
Figure 7 set to “Output”, the Display radio button will
not be available.) You can then enter values into
the “Display Zero”, “Display Full”, and “Display EGU”
boxes. When you have entered the appropriate
values, program the TDY with the new information by
using the steps on page 9, starting with Step 3.
