4. Slide the two white ferrules onto the probe, the narrower one on top of the
deeper, cup-shaped one.
5. Gently slide the bottom portion of the port adapter onto the probe, taking
care to orient the longer threaded section toward the top of the probe.
6. Remove the two O-rings installed in the dO2 port; first slide the white
Teflon O-ring onto the probe, then follow with the black 12mm port
adapter O-ring.
7. Do not yet close up all the elements of the port adapter.
8. Gently insert the probe into the appropriate port, allowing the O-rings to
seat fully into the port.

NOTE:
The fit may be snug. Gently rotate the probe as you press it into the port
to avoid breakage.
9. Finger tighten the bottom portion of the port adapter into the port.
10. Adjust the probe to the desired height; then, nesting the ferrules, close the
top portion of the adapter onto the bottom portion.
11. Finger tighten the knurled adapter assembly.
7.3.4 DO Probe Polarization
#
NOTE:
If the probe has been disconnected from a voltage source (either the unit’s
O
2
amplifier or a separate polarizing module) for longer than 5 minutes, it
will need to be re-polarized.
To re-polarize:
Connect the probe to the operating O
2
amplifier (or polarizing module).
Allow SIX HOURS FOR POLARIZATION prior to calibrating the probe.
7.3.5 DO Probe Calibration: Setting Zero
#
NOTE:
The DO probe is calibrated AFTER sterilization.
There are two methods to obtain zero for calibrating the DO probe. Review
both methods and use the one you prefer:
Method 1:
1. Remove the DO cable from the DO electrode.
2. Go to the CALIBRATION screen (
see Figure 23
) and select DO .
3. Enter
0
in the SET ZERO edit box (
see Figure 30 on the following page
),
then press SET ZERO .
