Assembling the Probe
Each HI-4433 series probe assembly consists of a spherical casing containing
the senor mounted on one end of a shaft and an extrusion that houses the
electronics. The sensor and electronics housing operate, and are calibrated, as a
unit. Since the appearance and layout of the electronics housing are the same
for all probes in this series, both the probe assembly and the housing are coded
with identical serial numbers to prevent mismatch.
To begin assembly, locate the probe and the corresponding probe housing.
Position the alignment arrows on the probe and housing so they are lined up, and
then gently press the probe into the housing.
