10. Pull excess cable up, through the probe nuts, until cable
is taut.
11. Tighten the probe nuts.
12. Cut off cable 1.35" (34 mm) above top of upper probe
nut, and strip off 1.25" (32 mm) of insulation.
13. Slide Teflon retaining bushing onto cable, and seat it into
the upper probe nut.
14. Slide clamp onto cable and seat it in the Teflon retaining
bushing.
15. Tighten both socket head clamp screws to approximately
35 inches/pound torque.
16. Slip mylar housing insulator over clamp.
17. Screw housing onto probe and tighten. Make sure conduit
connection is properly aligned for wire entry.
18. Remove housing cover.
NOTE: Refer to Electrostatic Discharge Handling Procedure on
page 9.
19. Remove the electronics assembly from the housing by
loosening the four mounting screws.
20. Locate the white wire, which is connected to the probe
terminal (P) on the circuit board, and connect its free end
