Transmitter Power
The relative power of the transmitter is continuously
measured and can be read out with the
Transmitter Power
parameter for the purposes of predictive sensor operation
and early detection of faults. The value is output at discrete
levels of 100 (Green), 75 (Yellow), 50 (Red), 25 (Red) and
0% (Red). A value of 255 indicates that a value has not yet
been determined at this point in time.
