Operation
This chapter thoroughly explains how to operate
the V

HECK.
Extending the probe
The Model 8330 V
ELOCI
C
HECK
contains a
telescoping velocity and temperature measuring
probe which is shipped in its collapsed position.
To expose the probe to the flow for air velocity or
temperature measurements, grasp the tip of the
probe and pull firmly.
To retract or collapse the probe, simply push the tip
of the probe straight toward the handle. When you
collapse the probe, be sure to allow room for the
cable to move freely out of the base of the probe.
Hindering the movement of the cable at the base of
the probe will make it difficult to collapse the
probe.
Always store the probe retracted when not in use in
order to protect the sensor.
