The display counts down the seconds remaining to flow Gas 1, then the
time remaining for sensing the O
2
concentration of Gas 1. Done Gas 1
indicates completion.
3. Remove the first calibration gas and apply the second calibration gas.
(Electronics will abort the calibration if this step is not done within 30
minutes). The LOI displays the following:
Apply Gas 2
Hit E when ready
4. Touch the Enter arrow to start the Gas 2 flow. The timer is activated and
the LOI displays:
Flow Gas 2 xxxxs
Read Gas 2 xxxxs
Done Gas 2
Stop Gas
Hit E when ready
5. Remove 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:
Purge xxxxs
The default purge time is three minutes. When the gas purge timer
times out, the Oxymitter 4000 begins to read the process O
2
.
Abort Calibration
Exits the calibration. After calibration gases are removed, and the purge times
out, the instrument goes back to normal operational mode.
Cal Constants - Results of the Calibration
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.
Previous Calibration
Values from the prior good calibration.
Failed Calibration
Bad calibration values are not loaded into the electronics.
Calibration Status
Calibration Step
The current step in an active calibration procedure.
Calibration Time
Time until the next scheduled calibration.
Next O2 Cal
Time until the next O
2
calibration, if different than the next scheduled
calibration.
