Introduction
Introduction
The PosiTector 6000 hand-held, electronic Gage
non-destructively measures the thickness of coatings on all metals,
quickly and accurately. It consists of a Gage body
(Standard or Advanced) and probe (Built-In or Separate).

Principles of Operation
F probes use the magnetic principle to measure the thickness of
non-magnetic coatings on ferrous metals.
N probes use the eddy current principle to measure the thickness of
non-conductive coatings on non-ferrous metals.
FN probes combine the full abilities of both the "F" and "N" probes.
Quick Start
Quick Start
The PosiTector 6000 powers-up when the center navigation button is
pressed. To preserve battery life, it powers-down after approximately
5 minutes of no activity. All settings are retained.
1. Remove the protective plastic cap (if supplied) from probe.
2. Power-up Gage by pressing the center navigation button.
3. Place the probe FLAT on the surface to be measured.
HOLD STEADY. When a valid measurement is calculated, the Gage
BEEPS twice and the measurement is displayed.
4. Lift probe AT LEAST 2 INCHES (5cm) from the surface between
measurements - OR - leave probe on the surface in the same
location for continuous measurements.
2
If memory is ON while continuous measurements are being taken,
only the last value on the display (when the probe is lifted) is
stored into memory. Scan (pg.15) stores ALL measurements into
memory.
Certification
All probes include a Certificate of Calibration. For organizations
with re-certification requirements, instruments may be returned at
regular intervals for calibration. DeFelsko recommends that
customers establish calibration intervals based upon their own
experience and work environment. Based on our product
knowledge, data and customer feedback, a one year calibration
interval from either the date of calibration, date of purchase, or
date of receipt is a typical starting point. Written calibration
procedures are available from DeFelsko Corporation at
no charge.
Golden Rule
Measure your uncoated part first! This quick zero-check
determines if a Calibration Adjustment is needed for your
substrate. (see pg. 10)
Next, lay the included plastic shims onto a bare surface and
measure them individually to ensure the Gage measures a known
thickness within tolerance.
Protective Cap
Some PosiTector 6000 models are shipped with a protective
plastic cap over the probe. Remove this cap prior to use.
Replace it when the Gage is not in use to protect the probe.
Wrist Strap
We recommend attaching and wearing the
supplied wrist strap.

Plastic Lens Shield
The LCD is covered with a thin plastic film for protection against
fingerprints and other marks during shipment. This film, while
usually removed before using the Gage, can be left in place to
protect against paint overspray. Replacements can be purchased.

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).
Availabe PosiTector 6000 Probes:
“Regular” - These constant-pressure, stainless
steel probes are hermetically sealed to be totally waterproof ideal for underwater use.
”Micro” - ideal for measuring small parts and
hard-to-reach areas. Available in 0, 45 or 90 degree angles.
”Thick” - ideal for thick, protective coatings.
“Xtreme” - ideal for measuring rough and hot surfaces up to 250°
C (500° F). Probe features an Alumina wear face and braided
cable.

Additional PosiTector Probes:
The PosiTector accepts a number of probe types including
magnetic and eddy current coating thickness, surface profile,
environmental and ultrasonic wall thickness probes. Perform the
latest software Updates (pg. 33) to ensure probe compatibility with
your Gage. For the latest information on probe interchangeability
see www.defelsko.com/probes
Two Probe Styles
:
* Built-in - sensor protrudes from bottom of probe connector
* Separate - sensor is attached to the probe connector by a
1.2 meter (3 foot) cable.
(Extended cables lengths available.)

Why is Measurement Important?
Dry Film Thickness (DFT) is arguably the single most important
measurement made during the application and inspection of
protective coatings. Coatings are designed to perform their
intended function when applied within a tight DFT range as
specified by the manufacturer. Correct thickness ensures optimum
product performance. Even the most basic specification will
require DFT to be measured.
Many physical and appearance properties of the finished coating
are directly affected by the film thickness including the color, gloss,
surface profile, adhesion, flexibility, impact resistance, and
hardness of the coating. The fit of pieces assembled after coating
can be affected when film thickness isn’t within tolerance.
Regular film thickness measurement helps control material costs,
manage application efficiency, maintain finish quality and ensure
compliance with contract specifications. Paint manufacturers
recommend target ranges to achieve optimum performance
characteristics and clients expect these parameters to be met.
Precisely measuring finish thickness has other benefits, too.
Whether to meet International Organization for Standardization
(ISO), quality, or customer requirements for process control,
companies need to verify coating quality to avoid wasting money
reworking product.

Calibration, Verification & Adjustment
Calibration, Verification & Adjustment
PosiTector 6000 probes non-destructively measure the thickness
of coatings on metals. Three steps ensure best accuracy…
1. Calibration - typically done by the manufacturer. All probes
include a Certificate of Calibration.
2. Verification - typically done by the user on known reference
standards such as plastic shims or coated thickness standards.
3. Adjustment - to a known thickness
Calibration
Calibration is the high-level, controlled and documented process of
measuring traceable calibration standards over the full operating
range of the probe, and verifying that the results are within the
stated accuracy of the probe. Calibrations are performed by the
manufacturer, their authorized agent, or by an accredited
calibration laboratory in a controlled environment using a
documented process.
PosiTector 6000 probes are shipped with a Certificate of
Calibration showing traceability to a National Metrology Institution.
For organizations with re-certification requirements, probes may
be returned at regular intervals for calibration. DeFelsko
recommends that customers establish calibration intervals based
upon their own experience and work environment. Based on
DeFelsko’s product knowledge, data and customer feedback, a
one year calibration interval from either the last date of calibration,
date of purchase, or date of receipt is a typical starting point.
Written Calibration Procedures are available online at no charge.
Verification
Verification is an accuracy check performed by the user on known
reference standards. A successful verification requires the Gage to
read within the combined accuracy of the probe and the reference
standards.
8
A reference standard is a sample of known thickness(es) against
which a user may verify probe accuracy. Reference standards may
be plastic shims, coated thickness standards, or sample parts
whose coating thickness has been determined using other means.
Verify accuracy at the beginning and the end of each work shift.
During the work shift, if the Gage is dropped or suspected of giving
erroneous readings, its accuracy should be re-verified.
In the event of physical damage, wear, high usage, or after an
established calibration interval, the probe should be returned to the
manufacturer for repair or calibration.
Adjustment
Adjustment, or Cal Adjustment, is the physical act of aligning the
probe’s thickness readings to match those of a known thickness
sample (removal of bias) in order to improve the accuracy of the
probe on a specific surface or in a specific portion of its
measurement range. 1-point or 2-point Cal adjustments are
possible.
Probes are factory calibrated and perform an automatic self-check
each time a measurement is taken. For many applications no
further adjustment is necessary after a Reset (pg. 14). Just check
ZERO on the uncoated substrate, then measure. However,
sometimes probe readings can be influenced by changes in
substrate shape, composition, and surface roughness or by
measuring in a different location on the part. That is why Cal
adjustments are made possible. The XX symbol disappears
whenever a Cal adjustment is made.
Where a Cal adjustment method has not been specified, use a
1-point method first. If measuring the included shims on your
uncoated surface reveals inaccuracies, use the 2-point method.
Factory Cal settings can be restored at any time by performing a
Reset (pg. 14), creating a NEW Cal setting (See Cal Memory
pg. 13), or by DELETING the adjustments made to the Cal 1
calibration setting (pg. 13). The XX symbol appears on the display
whenever factory Cal settings are in use.
With “FN” probes, calibration adjustments are made only to the
“F” or “N” mode (stored independently under a particular Cal),
whichever was measured last.

1-point Calibration Adjustment
Also known as an offset or correction value, there are 4 ways to
perform this adjustment:
(i) Simple Zero Calibration Adjustment
Measure your uncoated part. If the Gage does not read "0" within the
tolerance of the probe being used, lift the probe from the surface and
adjust the display down (-) or up (+) until it reads "0". Measure and
adjust until the average of a series of readings on the uncoated
surface is within tolerance of "0" .
(ii) Average Zero Calibration Adjustment
To establish “0” on a rough or curved surface a preferred method
to (i) is to take several readings on the uncoated part and
average the result.
(a) Select from the Cal Settings menu.
(b) Press (+) to select the number of readings to be used to
obtain an average, typically 3 to 10 readings. The greater the
variation between readings, the more readings should be taken
to obtain an average.
(c) Repeatedly measure the uncoated part. The Gage will wait
2 seconds after placing the probe on the surface to allow the
user to correctly position the probe on the surface. After the last
measurement the Gage will calculate a Zero which represents
the average of all the Zero readings taken.
(iii) Simple Adjustment to a Known Thickness
It is sometimes desirable to adjust the Gage to a known
thickness, such as a shim, rather than adjusting it to zero.
Measure the object. If the expected reading is not obtained
(within tolerance), lift the probe from the surface and adjust the
displayed reading down (-) or up (+) to the expected thickness.
Hold the button down to increase the rate of adjustment.

(iv) Average Adjustment to a Known Thickness
On rough or curved surfaces a preferred method to (iii) is to take
several readings on the known thickness and average the result.
(a) Select from the Cal Settings menu.
(b) Press (+) to select the number of readings to be used to
obtain an average, typically 3 to 10 readings. The greater the
variation between readings, the more readings should be taken
to obtain an average.
(c) Repeatedly measure the known thickness reference. The
Gage will wait 2 seconds between readings to allow the user to
correctly position the probe on the surface. After the last
measurement the Gage will calculate and display the reading
which represents the average of all the measurements taken.
If the expected reading is not obtained (within tolerance) lift the
probe from the surface and adjust the reading down (-) or up
(+) to the expected thickness and press .
2-point Calibration Adjustment
Preferred method for very unusual substrate materials, shapes or
conditions. Provides greater accuracy within a limited, defined
range.
1. Select from the Cal Settings menu.
2. Press (+) to select the number of readings to be used to obtain
an average on the thinner item, typically 3 to 10 readings. The
greater the variation between readings, the more readings
should be taken to obtain an average.

3. Repeatedly measure the thinner item. The Gage will wait for 2
seconds on the surface to allow the user to correctly position the
probe on the surface. After the last measurement the Gage will
calculate and display a thickness value which represents the
average of all the readings taken using the factory calibration
settings.
