3 CONFIGURATION
If the default configuration or the ordered configuration satisfies the application, then no further configuration is necessary, and the transmitter is
ready to be used. If a new setting is desired, this can be accomplished by the TxConfig and sent to the transmitter through the TxConfig USB
interface.
The
TxConfig interface and software compose the Transmitter Configuration Kit , with can be purchased separately from the manufacturer or
one of its distributors. The software can be updated for free on NOVUS website. To install it, run the Tx_setup.exe and follow the instructions.
The TxConfig interface connects the transmitter to the PC, as shown in figure below:
Figure 8 - TxConfig Interface USB connections
Once the connection is accomplished, you must run the TxConfig software and, if necessary, use the Help topic to arrange the transmitter
configuration. Figure below shows the TxConfig software main screen:

The fields in the screen mean:
1.
Measuring Range : Define the transmitter humidity and temperature measurement ranges, indicating a Lower Limit value and an Upper Limit
value.
The defined range cannot exceed the
Sensor Measuring shown in this same field, and cannot establish a range with a span less than the
Minimum Range indicated below in this same field.
When the Lower Limit is set to a value higher than the Upper Limit , the output current has a decreasing behavior (20 ~ 4 mA).
2. Sensor Failure : Establish the transmitter output behavior in the presence of a sensor fail. When Minimum is selected, the output assumes its
minimum value (4 mA) (down-scale). When Maximum is selected, it assumes its maximum value (20 mA) (up-scale).
3. Zero Correction : Correct, in the output value, small measurement errors presented by the transmitter.
4. Device Information : This field contains data that identifies the transmitter and is important in any queries to the manufacturer.
5. Read Device : When selected, allows you to read the configuration present on the connected transmitter.
6. Apply : When pressed, allows you to send the configuration to the connected transmitter.
Note : The factory default configuration is (unless otherwise specified or ordered):
• Measuring ranges: 0 to 100 °C and 0 to 100 % RH.
• Correction zero: 0 °C.
•
Upscale when sensor fails.
It is important to notice that the transmitter accuracy is always based on the total span of the used sensor, even if a narrower range is configured.
