CHAPTER 4

OPERATION

This chapter contains information that is needed to operate the HMT310.

Power Supply

Use a 10 … 35 VDC power supply (required minimum voltage varies

depending on the operating environment, functions and output type). For

instructions on selecting the correct operating voltage, see section Power

Supply Requirements on page 34.

Transmitter Start-Up

When the transmitter is connected to a power supply, there is a delay of

three seconds as the transmitter starts up. After the start-up is complete,

the measurement data is available from the analog output and serial line.

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

powerup.

For instructions on configuring the serial mode, see section Set Serial

Interface Mode on page 43.
