CAL_SLOPE 34.5-57.5 mV/Decade This parameter represents the slope value
used in the calculation of converting the
sensor voltage to an O2 value. The value of
this parameter may be manually entered or
calculated during a sensor calibration.
26
CAL_STATE See Table 1 Enumerated This parameter represents the present state
the calibration cycle is in. Refer to Table 1 for
the definition of states.
19
CAL_STATE_STEP 0: No effect
1: Go to next
step
2: Abort
Calibration
0 Enumerated This parameter is used to step the
transmitter through a sensor calibration.
Setting this parameter to 1 requests the
transmitter to move to the next cycle state of
the calibration procedure. The request is only
valid when the CAL_STATE value represents
a state that is waiting for an external event
such as the changing of a test gas value. The
transmitter will set this parameter value back
to 0 when it has completed processing the
step request. Setting this parameter to a
value of 2 will cause the present calibration
to be aborted.
20
CAL_STATE_TIME 0-1200 Sec This is the time in seconds remaining in the
present calibration state. 21
CAL_TRACKS This parameter is no longer used. 24
CELL_MV_VALUE ± INF mV This is the raw signal from the O
2
sensor. 43
CELL_TC_MV_VALUE
-1000.0 - 500.0 mV This is the raw signal from the O
2
sensor
thermocouple.
44
CELL_TEMPERATURE This is the current temperature of the O
2
sensor.
54
CHECKSUM 0000 N/A This is the checksum of the Oxymitter
software. 61
COLD_JUNC_MV_VALUE ± INF mV This is the raw signal from the
case/thermocouple cold junction sensor.
45
COLLECTION_DIRECTORY See Transducer Block Specification, part 1.
FF-902, page 11. 12
CONFIG_CHANGED 0-255 0 N/A This indicates that a static parameter in the
Oxymitter has changed by some means
other than Fieldbus. 51
TB_DETAILED_STATUS 0-16777215 0 Enumerated This is a bit-enumerated value used to
communicate the status of the Oxymitter.
(This is similar in nature to the command 48
status bits in HART.)
55
HIGH_CASE_TEMP 0-10000.0
o
C This is the highest temperature that has been
measured inside the electronics enclosure.
