Instrument Self-Test
On initial power on, the Air XD is programmed to perform a set of initialisation tests which are listed
and described below. Throughout general function, the Air XD will periodically perform these tests to
ensure correct operation.
•
OPC sensor comms check
Ensures communications and correct functionality of the OPC sensor.
•
OPC temp sensor test
Ensures the OPC sensor is operating within the specified safe temperature limits.
•
4-20mA self-test
During instrument start up and initialisation, each 4-20mA output will perform a calibration routine which
involves sweeping the output from 0-20mA before returning to 4mA. After this has been completed, the
output will return to configured functionality.
•
Data logging comms test
Ensures communications and correct functionality of the Air XD memory module.
•
EEPROM memory test
Ensures communications and functionality of the EEPROM is correct and that custom defined user
settings are not lost.
