9. To output the transducer values (P1,P2,P3) separately and the

average value (P). Indicates errors if the maximum pressure

difference between the transducers is exceeding the defined value.

The two-or three-digit error field in the end of the line is expressing

the error state of the transducers. Number 1 means error and number 0

normal state. The first digit shows state of transducer 1 (P1), second

digit shows state of transducer 2 (P2) and the third digit shows

transducer 3 (P3).
