Description
The amount of time cali-
bration gas should flow be-
fore a reading is taken.
The amount of time before
returning the output to
process after calibrating.
Enable/disable calibration
recommended alarm.
Calibration result.
The current state of the cal-
ibration cycle.
Initiates a calibration or
goes to the next calibration
step.
The time left in the current
calibration step.

cation, Part 1. FF-902, page

and 4.5.
See FF-903, Section 3.3.
The time between auto-
matic calibrations of the
combustibles sensor.
The value of the combusti-
bles test gas.
The combustibles calibra-
tion constant.
The raw value of the com-
bustibles level input. This is
the difference between the
active and reference RTDs.
This is the constant value
calculated from the last
failed combustibles calcula-
tion.
This is the slope value cal-
culated from the last failed
combustibles calibration.
