12. Using a flat blade screwdriver, snap the new retainer clip over the cell clip to
provide a strong contact between the cell clip and the cell. The retainer clip is
concave; place the pointed end away from the cell.
13. Place the metal O-ring on the slot at the end of the cell assembly. Slide the
cell assembly into the inner probe assembly until the threads engage. On the
flange end, slide the sheet metal plate over the ceramic tubes that contain the
cell leads (see Figure 6-3).
14. With the probe oriented in front of you so the cell assembly end is on your
right and the sheet metal plate is on your left, rotate both the sheet metal plate
(handle end of probe) and the left hex nut clockwise at the same time until
the left hex nut is fully threaded into the inner probe assembly.
To prevent twisting of the cell leads, keep the mark on the left hex nut and
the orientation of the white cell lead from being more than one quarter turn
from each other.
If you don’t have two people and the probe is long, you may find it
difficult to turn both ends at the same time. In this case, turn the left
hex nut one quarter turn, then turn the heater one quarter turn until
the left hex nut is threaded into the inner probe assembly.
15. Position a 1” open end wrench on the wrench flats of the inner probe as-
sembly. Place another 1” open end wrench on the left hex nut of the cell
assembly, and tighten the left hex nut until the mark on the left hex nut is 90
degrees away from aligning with the mark on the inner probe assembly.
16. Align the sheet metal plate holes with the holes on the inner probe assembly.
17. Insert 10-32 screw and lock washer into the sheet metal plate and tighten
onto the flange using a flat blade screwdriver. Ensure that other holes remain
aligned while tightening this screw.
18. Slide the heater into the inner probe assembly until the marks you placed on
the heater in Step 2 of the removal section align with the U-bolt, then tighten
the U-bolts using a 3/8” nut driver.
19. Reinstall the probe into the process by reversing the steps of the R emoving
Inner Probe Assembly section earlier in this chapter.
20. Perform a calibration.
