Temperature increases due to compression warming absolutely must be taken
into account. In these cases it may be necessary to throttle the rate of change
of pressure or reduce the permissible medium temperature.
The end user must ensure that the instrument is connected to the equipotential
bonding of the end-use application via the process connection. The sealings
used at the process connection must be electrically conductive. Alternatively,
take other measures for grounding.
