6.4.2 SMITC (Thermocouple SMART Module)
NOTE
The eDAQ
lite
uses the full-scale min and max values defined in the ELHLS parent
channel to configure the converter that outputs analog voltage as a function of
computed thermocouple temperature. To optimize the temperature measurement
accuracy, set the full-scale values as close as possible to the temperature extremes
expected in the test.
Thermocouple Type
Select the type of thermocouple as T, J, K or E. If the channel is calibrated, delete the
calibration before selecting a different thermocouple type.
Hardware Configuration
Click the hardware button to view the SMART module user data parameters as they
are defined in the hardware setup configuration. Note that TCE does not update
reprogrammed SMART modules until a hardware query is performed.
6.5 Temperature Input Channels
6.5.1 Thermocouple
Add a thermocouple input channel to any ELNTB connector. For more information on
the ELNTB layer, see
“ELNTB (Non-Isolated Thermocouple Layer)” on page 95 .
Output Data Type
The output data type is always 32-bit float.
Thermocouple Type
Select the type of thermocouple as T, J, K, E, or thermocouple undefined.
Replace Lost Data Samples
Set this field to yes to fill the data samples with a fixed value of +1.0e+06 when the
input voltage to an input channel is out of the thermocouple’s operating range. The
most common cause for this is a broken thermocouple or not having a thermocouple
plugged into the front panel input connector.
NOTE
Both lost data samples and out of range data samples are flagged as invalid in the test
run pipe frames (i.e., the frames of data that are passed to the computed channel and
DataMode modules). This allows the Valid Data Gate computed channel to keep track
of all invalid data samples. For more information on the Valid Data Gate computed
channel, see
“Valid Data Gate” on page 1

6.6 Bus-Oriented Input Channels
Each bus interface supports channels created from channel databases. Each channel
in the database has pre-defined parameter values which are automatically transferred
to the created channel. The bus-oriented input channels are:
