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.
Example:
The humidity sensor has a maximum range of 0 to 100% RH and an accuracy of 3% at 25 ° C (77 °F), as shown in
Figure 12
. We can have an
error of up to 3 % RH in any adopted range.
This error is even in a wide range as the maximum (0 to 100% RH) or in a narrower range, such as 20 to 80 % RH.
Serial port configuration error may occur when other software uses the same serial port. Finalize all software that uses the serial port
specified for TxConfig before using it.

RETRANSMITTING THE DEW POINT
To use the
RHT-XS
and transmit the dew point instead of relative humidity, you must follow the steps below:
•
Connect the device to the
TxConfig
interface and run the software.
•
The software will recognize the
RHT-XS
model, read its configuration, and make it available to the user.
•
In the "Options" menu, enter "Humidity Reading Type" (only available when an
RHT-XS
model is detected) and select the "Dew Point" option. At
this point, the values of the scales will be converted to the dew point unit, i.e., degrees (Celsius or Fahrenheit, as selected).
•
Proceed with the rest of the configuration and send the device via the "Apply" button.

Dew point
If the "Humidity Reading Type" option does not appear even after the
RHT-XS
transmitter is correctly detected, the
TxConfig
software version is
probably old and does not support this feature. In this case, download and update the latest version.
