Table 10: Error state iterpretation
Reply acronym Error interpretation
1000000 lse Precise clock of RTC failure
0100000 hse Precise clock of CPU failure
0010000 bsen Error of some of the three transducers
0001000 sum Error of pressure weighted average value or difference limit
0000100 flash Flash memory failure
0000010 sht Compensation RH sensor error
0000001 crc Flash configuration CRC error
6.6 “errors” Print error message
This command can be used to discover communication problem with the sensor element, with
the internal digital/analog converter, and to verify FLASH checksum. The errors<cr> command
returns three binary values; 0 means no error, 1 means error state.
Example:
errors<cr><lf>
0000000(lse, hse, bsen, sum, flash, sht, crc)<cr><lf>
In the example, there is no error state indicated (seven zeros).
In case of signalized errors, or other problems, please refer to section 11 on page 89.
6.7 “sdi12a” SDI-12 address change
This command is used to change the sensor address on SDI-12 bus. The SDI-12 address is
one character. It can be number 0 to 9, lower-case character a to z or upper-case character A
to Z.
Default SDI-12 address is 0.
sdi12a<cr>
New SDI-12 address: 8<cr>
wait..OK<cr><lf>
The example shows setting SDI-12 address to 8.
In case of incorrect new address (not within correct ranges, see above), the barometer replies:
Wrong format<cr><lf>
