APPENDIX F. TROUBLESHOOTING
If there is suspicion that sensor returns wrong data and / or operates improperly, it is
necessary to check its status by sending command <DATAE2> (see Appendix C.2.1). It returns
concentration value and two status bytes. If any bits of status bytes are true, check their meaning
in Table 11 and follow to specified recommendations. If suspicion of error or status corresponding
to error persists, please contact support.
Contacting support, send log file with periodic responses to command <F>, which is intended
exclusively for detailed diagnostics. It returns comprehensive information on sensor readings and
its status. Sensor power consumption stated in Table 4 is not guaranteed while using this
command. Command <F> returns
72 bytes in ASCII format and “0D” symbol. Unlike <DATAE2>, it
returns status word whose value corresponds to certain combination of true status byte bits (see
Table 11). Detailed description of command <F> is contained in Table 15.
Sending rate of <F> command should not be more than 0.6 Hz.
In case if status word value is stable, log file with few (approx. 10) responses is enough. In
case if status word varies eventually or periodically, log file must contain sufficient number of
responses obtained before status word occurs and in time of its occurrence.
It is recommended to provide in end-user equipment possibility to form a log file using
command <F>.
