DeGas (only for HPT 100)

The degassing mode can be activated/canceled with a write request and the status be

queried with a read request as well.

While the transmitter is in the degassing mode, no valid measuring values are transmitted.

Transmitter adjustment

To equalize a transmitter there must first be set a pressure adjustment point and then the

actual pressure value. If the setting for the pressure adjustment point is missing or if another

telegram is inserted between the two steps, an error signal is generated when writing the

pressure value.
