1518541200. To set the first calibration time at February 13th, 2018 – 5:30PM the UTC value in seconds
will be 1518543000. The register will accept values from 1518541200 (Current date and time in seconds) to
1523725200(Current date and time in seconds + 60 days in seconds).
6. Activate each calibration schedule(Register Address : 40132, 40142, 40152, 40162). The value should
be set as (0x01).
7. Set the pressure sensor status (Register Address : 40175). Set it to either ambient sensor(0x01) or
manual pressure input(0x03). If manual pressure input is selected, then set the pressure value (Register
Address : 40172) and pressure unit(Register Address : 40174). The pressure value can only be set when
auto calibration is disabled. The pressure unit can be mBar(0x01), inch H20(0x02), Bar(0x03), Torr(0x04),
PSI(0x05).
8. To set the Span gas oxygen value and unit, use the Register Address 40177 to set the oxygen value.
Then set the span gas oxygen unit (Register Address : 40176). The value can be PERCENTAGE (0x01) or
PPM (0x02).
9. Set zero drift tolerance, first set the zero-drift tolerance unit (Register Address : 40181). The value can
be PERCENTAGE (0x01) or PPM (0x02). Then set the zero-drift tolerance value (Register Address : 40179).
10. Similarly, to set span drift tolerance, first set the span drift tolerance unit (Register Address : 40184).
The value can be PERCENTAGE (0x01) or PPM (0x02). Set the span drift tolerance value (Register Address :
40182).
11. Set zero purge time (Register Address : 40185). The value should be between 1 and 30 in minutes.
12. Set span purge time (Register Address : 40187). The value should be between 1 and 30 in minutes.
13. Set recovery time (Register Address : 40189). The value should be between 1 and 120 in seconds.
14. Enable auto calibration (Register Address : 40131). The value should be set to (0X01). At this point the
AutoCal is activated and will start according to the schedule set.
15. To manually start the auto-cal, set register address 44000 to 0X04 to activate.
16. To stop the auto-cal before its time expires, set the same register address 44000 to 0X05.
