Description
Indicates whether the com-
bustibles calibration con-
stants should be updated
after combustibles sensor
zero.
A bit-enumerated value
used to communicate the
status of the OCX. (This is
similar in nature to the
command 48 status bits in
HART).
A bit-enumerated value
used to communicate the
status of the OCX. (This is
similar in nature to the
command 48 status bits in
HART).
The current temperature
reading of the electronics
temperature sensor.
The current voltage read-
ing of the electronics tem-
peratue sensor.
This initiates a blowback
cycle.1 = Do a manual
blowback
The calculated line fre-
quency.
The calculated line voltage.
This is the maximum elec-
tronics temperature seen
by the analyzer.
This resets the maximum
temperatures.
See FF-891, Section 5.3.
The time between auto-
matic calibrations of the O
2
sensor.
The value of the O high
2
test gas. This gas is also
used as the low gas for cali-
brating the combustibles
temperature.
