CHAPTER 5
OPERATION
This chapter contains information that is needed to operate the DPT146.
Transmitter Start-Up
When the transmitter is connected to power supply, there is a delay of
five seconds as the transmitter starts up. After the start-up is complete,
the measurement data is available from the analog outputs or serial line.
For a description of how the diagnostic functions of the sensor affect the
availability of live measurement at start-up, see section DPT146 Startup
Sequence on page 22.
If serial line output is used, note that the transmitter will behave
according to the configured serial mode:
- In STOP mode, the transmitter outputs the transmitter model and
software version. This is the default mode.
- In RUN mode a measurement output starts immediately.
- In POLL mode the transmitter does not output anything after power-
up.
For a description of the modes, see section Set Serial Line Operating
Mode on page 50.
