Probes

The PosiTector 6000 consists of a body and
a probe. A wide selection of interchangeable
probes are available. Each retain their own
unique calibration information. Gage bodies
(Standard or Advanced) accept ALL probes. See

Gage Info (pg. 15) to find your body and probe type. More probe
information is available at www.defelsko.com/p6000.

To disconnect a probe from a body, power-down the
Gage and pull the plastic probe connector horizontally
(in the direction of the arrow) away from the body.
Reverse these steps to attach a new probe.

When powered-up the PosiTector automatically
determines what type of probe is attached and does a self-check.
Coating thickness robes “sense” when they are near metal and
immediately attempt a measurement followed by another every
2 seconds. They stop when removed from the vicinity of metal and
power-down after 5 minutes of no activity.

This continuous measurement feature is intended to allow careful
probe placement on small or odd-shaped surfaces. Ignore all
readings taken before the probe is properly placed.

The PosiTector 6000 probes calculate coating thickness
measurements using either the magnetic principle
(F probes - ferrous models) or the eddy current principle
(N probes - non-ferrous models). Combination FN probes
(ferrous/non-ferrous) use both principles.

FN probes first attempt a measurement using the magnetic
principle and will display a reading with the letter "F" if the coating
is non-magnetic over steel. If the coating is non-conductive over
metal, then the probe will automatically attempt a measurement
using the eddy current principle and display a reading with the
letter "N” (see also N Lock pg. 12).
