ERROR MESSAGES

The HMP260 transmitters go through a self-diagnostics procedure when the power is
switched on. When the procedure does not reveal any errors or faults, the transmitter
starts operating normally. If errors or faults are found, the transmitter outputs an error
message. The error messages can be divided into two groups: error messages after reset
and error messages during operation.
