O2 Analyzer Calibration in Progress
Informs the user that an O
2
calibration is in progress.
WARNING: Low O2 Lockout and O2 Trim are Bypassed during Calibration. YES=Continue,
EXIT=Abort
A warning appears to remind the technician O
2
trim and low O
2
alarm are disabled during O
2
probe calibration.
WARNING: Cal Gas % differs from O2OldCalData % by more than 0.75%. Press YES to
Proceed, or EXIT
A warning appears if the calibration gas O
2
concentration is different than the calibration gas setpoint input to the FlexFit. This
may be normal if a new calibration gas bottle with different O
2
concentration is being used.
Connect LOW O2 Cal Gas, press YES when Flow is 2-3 SCFH
The FlexFit is waiting for the technician to indicate that the low O
2
calibration gas is being applied to the detector.
Signal Settling... Please Wait
The FlexFit is waiting for the calibration gas to stabilize.
Close Cal Gas Valve. Press YES when Closed.
The FlexFit is waiting for the technician to remove the calibration gas from the detector.
Connect HIGH O2 Cal Gas, Press YES when Flow is 2-3 SCFH
The FlexFit is waiting for the technician to indicate that the high O
2
calibration gas is being applied to the detector.
Purging Cal Gas... Please Wait
The FlexFit is purging calibration gas from the detector so that an accurate reading can be detected.
Purge Complete. Press EXIT
The calibration gas purge is complete.
Calibration Successful.
Calibration completed successfully.
ERROR: Calibration Data is Bad. Press YES to load Defaults and continue, Press EXIT to
abort.
There is a problem with the calibration data store in the FlexFit CC. Perform an oxygen sensor calibration. If the problem
persists, replace the FlexFit CC.
ERROR: Cell mV was too High. Press EXIT
The calibration gas O
2
content was too low, the calibration gas contains combustibles, or cell wiring is partially open.
ERROR: Cell mV was too Low. Press EXIT
The calibration gas O
2
content was too high, calibration gas ow was too low, the outer lter is cracked and calibration gas is
escaping, or ambient air is leaking into the O
2
cell.
ERROR: Cold Junction Temp Out of Range, Press EXIT
Check O
2
cell thermocouple eld wiring. If wiring is good, there is a problem with the FlexFit. If the problem persists, replace
the FlexFit CC.
ERROR: New Offset is Out of Range. Press EXIT
Cal gas O
2
content is different than expected according to parameters "P2.3.13 O2 Low Cal Gas %" and "P2.3.14 O2 High Cal
Gas %". Check calibration gas O
2
content. O
2
cell may be old or damaged.
ERROR: New Slope is Out of Range. Press EXIT
Cal gas O
2
content is different than expected according to parameters "P2.3.13 O2 Low Cal Gas %" and "P2.3.14 O2 High Cal
Gas %". Check calibration gas O
2
content. O
2
cell may be old or damaged.
ERROR: Not in Commission Mode, Press EXIT
The FlexFit must be in commission mode to perform an O
2
calibration.
ERROR: O2 A/D is Bad, Press EXIT
There is a problem with the FlexFit. If the problem persists, replace the FlexFit CC.
ERROR: O2 Cell Open Circuit, or High Combustibles, Press EXIT
O
2
cell voltage input is greater than 130 mV. If O
2
cell is cold, wait for it to warm up. Check cell eld wiring and detector for an
open circuit. This message will appear if combustibles are present in the stack gas.
