Bench Check using a FDT/DTM Software
This section provides information on checking the TDZ

/ THZ

using a PC with PACTware (an
FDT frame application). For users who already have an FDT Frame Application, all the following
information is still relevant. For more information on FDT/DTM please refer to www.fdtgroup.org.
To perform the bench check of your THZ

/TDZ

set up the equipment in Table 2.4 as shown in
Figures 2.14.

as appropriate for your application. If possible, use the exact temperature sensor (RTD
or thermocouple) that you will be using in your final application. Apply power to the THZ

/TDZ

and see that it is reading the correct ambient temperature and providing the correct output for the
given input.
Example: If your TDZ
3
is configured to measure a temperature range of 50-100° F and is now
on your test bench and is reading an ambient temperature of 72° then you should expect an
output of 11.04mA.
If it is not feasible for you to use the actual temperature sensor for your bench test, or if your
desired temperature range is nowhere near your ambient temperature, then use a temperature
simulator (such as a Fluke 725 or similar) to provide your input.
Once your bench setup is complete you can now use your FDT/DTM software to check the
transmitter’s dynamic variables and analog output. If using PACTware you can use the
“Measured value” menu command to view the transmitter’s real time values (see Section 5.24 of
this manual).
