NOTE:
Measurements performed by the transducer when supplied from the AR956 programmer are not reliable.
The AR956 programmer is intended only to supply the transducer during configuration of parameters using the
ARSoft-CFG software. During normal operation, the transducer should be supplied in the standard manner.
