encoding.
Modes
Rotating Mode
While the sensor/transmitter in the Rotating Mode, it shall satisfy
the following requirements. The sensor/transmitter shall transmit
an instantaneous measured data, if a pressure change of 2.0 psi
from the last transmission or greater has occurred with respect to
the following conditions. If the pressure change was a decrease of
pressure, the sensor/transmitter shall transmit immediately every
time it detects the 2.0-psi or greater pressure changes from the
last transmission.
If the pressure change of 2.0 psi or greater was an increase of
pressure, the sensor shall not react to it.
