Be sure that the configuration lock jumper is in the unlock position.
When the jumper is in the lock position (shorting the two-pin header) the
HHC375 is not permitted to make any changes. However, parameters
are readable. If fault messages appear, they must be handled before
proceeding with HART communications. Before communications
proceeds all error messages must be cleared. For example, the
following message is displayed if the instrument has been serviced and
the air is not connected.
