(Figure 6-5).
3. Depress and remove the J1 (cell and
T/C) connector from the J1 socket.
Loosen the three captive mounting
screws on the microprocessor board
(top board).

accessed by moving the J1 connector
leads out of the slot on the microproc-
essor board and sliding the electronic
assembly partially out of the housing
(Figure 6-6).
5. Squeeze the J8 connector on the sides
and carefully remove. The electronic
assembly can now be completely re-
moved from the housing.
6. Remove the four screws (7, Figure 6-1)
from the probe finned housing. The
probe and the electronic housing can
now be separated.
7. When reinstalling or replacing the
electronic housing, make sure that O-
ring (10) is in good condition. Place the
J1 and J8 connectors in the hole on the
flat side of the electronic housing.
8. Hold the J1 and J8 connectors out and
to the probe side of the electronic
housing. Make sure that the conduit
port of the electronic housing is on the
same side as the CAL and REF gas
ports. Replace the four screws and
tighten.

power supply board. Make sure the
connector is secure.
