Write any value to trigger a calibration
for the low oxygen calibration point.
If no calibration error regarding the low
point (bits 2 to 7, see Table 4.1)
occurred, the measured phase and
temperature values (or the manually set
temperature value) will be written in the
registers for Cal0 (register HR5521) and
T0 (register HR5523)
The timestamp the last low point
calibration point was performed
For details see Section 4
nd
Write the desired O -2 value to trigger
2
a calibration for the high oxygen
calibration point. The unit is set in
HR5535.
If no calibration error regarding the high
point (bits 10 to 15, see Table 4.1)
occurred, the measured phase,
pressure, and temperature values (or
the manually set temperature value) will
be written in the registers for Cal-2
nd
(register HR5529), T2 (register
HR5531) and pATM (register HR5533)
The timestamp the last high point
calibration point was performed
