c. Cal Constants – Results of the
Calibration
1. Current calibration – If the calibration
passed these values will be updated.
Log these values onto the calibration
log sheet supplied. If the process has
high levels of particulate, the response
back to the process after cal gas is
also removed.
2. Previous Calibration – Values from the
prior good calibration.
3. Failed Calibration – Bad calibration
values are not loaded into the elec-
tronics.
d. Calibration Status
1. Calibration Step – The current step in
an active calibration procedure.
2. Calibration Time – Time until the next
scheduled calibration.
3. Next O2 Cal – Time until the next O
calibration, if different than the next
scheduled calibration.
