4. T ouch the Enter arrow to start the Gas
2 flow. The timer is activated and the
LOI displays:
Flow Gas 2xxxxs
Read Gas 2xxxxs
Done Gas 2
Stop Gas
Hit E when ready
5. Rem ove the second calibration gas
and cap off the calibration gas port.
Then, touch the Enter arrow to indicate
completion. The timer is activated and
the LOI displays:
Purgexxxxs
The default purge time is three min-
utes. When the gas purge timer times
out, the Oxymitter 4000 begins to read
the process O2.
b. Abort Calibration
Exits the calibration. After calibration gases
are removed, and the purge times out, the
instrument goes back to normal operational
mode.
c. Cal Constants – Results of the
Calibration
1. Curr ent 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. Prev ious Calibration – Values from the
prior good calibration.
3. Failed Calibration – Bad calibration
values are not loaded into the elec-
tronics.
d. Calibration Status
1. Cal ibration Step – The current step in
an active calibration procedure.
2. Cal ibration Time – Time until the next
scheduled calibration.
3. Nex t O2 Cal – Time until the next O2
calibration, if different than the next
scheduled calibration.
