CALIBRATION WITH LOI

9-6
Refer to Figure 6-4 for a view of the LOI menu tree. To calibrate the Oxymitter
5000 from the LOI, access the CALIBRATION/ Start Calibration menu.
CALIBRATION/Start Calibration
This is the starting point for calibrations. The LOI will instruct the user through
this entire procedure. Select "Abort Calib" at any time to abort the calibration.
1. The LOI displays the following:
Apply Gas 1
Hit E when ready
The Oxymitter 5000 is ready to accept the first calibration gas. Apply the
first calibration gas. (Electronics will abort the calibration if this step is
not done within 30 minutes).
2. Touch the Enter key to start the Gas 1 flow. A timer is activated to allow
the calibration gas adequate time to flow (default time of five minutes).
The LOI displays:
Flow Gas 1 xxxxs
Read Gas 1 xxxxs
Done Gas 1
The display counts down the seconds remaining to flow Gas 1, then the
time remaining for sensing the O
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 5000 begins to read the process O
Abort Calibration
Exits the calibration. After calibration gases are removed, and the purge times
out, the instrument goes back to normal operational mode.
