6 Measurement Output
Measurements are transmitted in accordance with UMB binary protocol (Factory Settings).
You can find an example of a measurement request in different protocols and a complete
summary of the list of channels in the Appendix.

Note: For the correct calculation of relative air pressure, the altitude of the location must be
entered in the device configuration (see Figure 11 on page 28). The factory setting for
altitude is 0m; in this way both measurement variables deliver the same values.
