CAUTION

In pressurized processes it is essential to tighten the supporting nuts and
screws very carefully to prevent loosening of the probe by the action of
pressure.

NOTE

When the DMT340 is installed in a process with a pressure differing
from the selected operating pressure at the time of ordering, please enter
the pressure value of the process into the transmitter memory. You can
enter the value in the following ways:

- using the display/keypad option
- using the buttons on the motherboard
- using the serial line
- using the Modbus protocol

See section Pressure Compensation Setting on page 106. If you are
using Modbus, see section Configuration Registers on page 185.
