24, Calibration Ready for Next Step
The calibration sequence has been initiated, and the Module requires data commands from the
host to proceed to the next calibration step.
25, Calibration in Progress
The Module is carrying out the calibration process.
26, Calibration OK
The Module has successfully performed a calibration, and the new constants have been stored in
the EEPROM. After successful User Calibration, the Last Calibration Date is also updated to
reflect the new information.
Soft Faults
Soft faults are conditions which halt Module operation, including transmission of CO
2
waveform
and breath data packets, until the condition is cleared. The Module can accept commands while
in the soft fault state.
Calibration Faults
Calibration faults abort calibrations. The Module requires a new calibration command to reinitiate
the calibration sequence after the error is cleared. Calibration fault messages include 28 through
2A. To clear a calibration fault, send a new host command. If the Module does not accept the
command, a software reset may be required.
Calibration faults are listed in the following table.
28, Unable to Perform Calibration, Parameters Missing
The Module timed out while waiting for a data command from the host during the calibration
sequence. The calibration sequence must be completed within 30 minutes of initiation.
