e.  Slide assembled probe junction box and in-

ner probe assembly into probe tube. To
align calibration gas tube with correspond-
ing hole in backplate (A, B, Figure A-1), in-
sert aligning tool (included in probe
disassembly kit, P/N 3535B42G01) through
hole in backplate and into calibration gas
tube, while sliding the heater strut into the
probe tube. Secure with screws. Reinstall
hoses and probe junction box cover.

f.  Power up system. Monitor thermocouple

output.  It should stabilize at set point ±0.2
mV. Recalibrate probe per Instruction Bulle-
tin applicable to your electronics package.

A high temperature, corrosive environment kit is
available when the probe is exposed to these
types of operating conditions. The kit includes
stainless steel tubing and teflon fittings for in-
side the probe junction box. The kit part number
is 4843B93G01.

 

1.  Disconnect and lock out power to digi-

tal electronics. Using heat resistant
gloves and clothing, remove probe
cover. Squeezing tabs on hose clamps,
remove hoses from probe junction box
(Figure A-19).
