PosiTector 200 probes are available for measuring a wide variety
of coating thickness applications.
B probe - 13 to 1000 microns (0.5 to 40 mils)
Ideal for polymer coatings on wood, plastic, composites, etc.
C probe - 50 to 3800 microns (2 to 150 mils)
Ideal for thicker coatings on concrete, fiberglass, etc.
D probe - 50 to 7600 microns (2 to 300 mils)
Ideal for thick, soft (attenuative) coatings such as polyurea
NOTE:
Range limits apply to polymer coatings only.
Additionally, the PosiTector accepts a number of probe types
including magnetic and eddy current coating thickness, surface
profile, environmental and ultrasonic wall thickness probes.
For the latest information on probe interchangeability, see
www.defelsko.com/probes
Couplant is required to propagate ultrasound into the coating.
Water is a good couplant for smooth coatings. Use the supplied
glycol gel for rougher coatings. While it is unlikely that the
couplant will damage the finish or leave a stain on the surface, we
suggest testing the surface by using the couplant on a sample. If
testing indicates that staining has occurred, a small amount of
water can be used instead of couplant. Consult the Material Safety
Data Sheet available on our website and your coating supplier if
you suspect the couplant may damage the coating. Other liquids
such as liquid soap may also be used.

PosiTector 200 - Theory of Operation
PosiTector 200 probes emit a high frequency sound pulse that
travels into the coating via a coupling gel and reflects from ANY
surface that is different in density. Coating thickness readings are
obtained by measuring the time taken for the ultrasonic signal to
propagate from the probe to the coating/substrate interface and
back. The travel time is divided by two and multiplied by the
velocity of sound for the coating to obtain the thickness of the
coating.

How to Measure
How to Measure
1. Remove the protective rubber cap from probe.
2. Power-up Gage by pressing the center navigation button.
3. Apply couplant (see pg. 2) to the surface of
the part.
4. Place the probe FLAT on the surface and
press down.
5. Lift the probe when you hear a double BEEP,
- OR - leave probe on the surface in the same location for
continuous measurements.
6. When completely finished, wipe the probe clean of couplant
then return the Gage to the protective pouch. There is no need
to disconnect the probe from the PosiTector during storage.
Couplant
The PosiTector 200
interprets the largest
“echo” within the
selected range as
the coating/coating
or coating/substrate
echo.

Calibration, Verification and Adjustment
Calibration, Verification and Adjustment
Three steps ensure best accuracy…
1.Calibration - typically done by the manufacturer or a qualified
lab. All probes include a Certificate of Calibration.
2.Verification of Accuracy - as done by the user on known
reference standards such as the included plastic shims or
optional coating thickness standards.
3.Adjustment - to a known thickness.
Calibration
Calibration is the controlled and documented process of
measuring traceable calibration standards and verifying that the
results are within the stated accuracy of the Gage. Calibrations
are typically performed by the Gage manufacturer or by a certified
calibration laboratory in a controlled environment using a
documented process.
Verification
Verification is an accuracy check performed by the user using
known reference standards. A successful verification requires the
Gage to read within the combined accuracy of the Gage and the
reference standards.
Adjustment
Adjustment, or Calibration Adjustment is the act of aligning the
Gage's thickness readings to match that of a known reference
sample in order to improve accuracy of a gage on a specific
coating. See Thickness pg. 6

Cal Settings Menu
Cal Settings Menu
Zero
The probe must be periodically zeroed using the Zero menu option
to compensate for both extreme temperature and probe wear
effects. Before using, allow the probe to reach ambient
temperature. Wipe the probe clean of couplant. The icon
appears after probe is zeroed.
If measurements will be made in extreme hot or cold temperatures,
it is recommended to Zero the probe in the working environment.
If measurements will be made on rough substrates, it is
recommended to periodically Zero the probe to compensate for
wear.
Set Range
The measuring range of each probe can be changed depending on
the specific application or the expected thickness range of the
coating system.
For most applications, the default range values do not have to be
adjusted. But some conditions, like surface roughness, may cause
the Gage to display very low or non-repeatable readings. In this
case, the low range may be increased to cause the Gage to only
display readings above the Lo value set by the user.
To adjust Set Range values...
1. Select or .
2. Use the (-)(+) buttons to decrease/increase the displayed value.
IMPORTANT:
The PosiTector 200 interprets the largest “echo” or “echoes”
within the selected range as the coating/coating or
coating/substrate echo. If the coating thickness is outside this
range, incorrect or dashed readings may occur.
5
Here are some typical Range settings...
Expected paint thickness Lo Hi
500µm (20 mils) on concrete 130µm (5 mils) 1000µm (40 mils)
50µm (2 mils) on wood 25µm (1 mil) 250µm (10 mils)
Thickness
The PosiTector 200 measures most polymer coatings accurately
out-of-box with no adjustment required.
To determine if an adjustment is necessary, select a coating
sample of known thickness as close as possible in composition to
the intended application. For best results, the thickness of the
sample should be equal to or slightly greater than the maximum
expected thickness of the coating to be measured.
Measure the coated sample. If the average of a series of
measurements on the sample is not close to the known
thickness...
1. Select the Thickness menu option.
2. Use (-) or (+) to decrease/increase the displayed measurement
thickness value to match the known thickness of the sample.
3. For Advanced models with multiple layers selected, use the
Down navigation button to select the next layer and adjust as
necessary.
4. To save adjustments, use Down navigation button to highlight
OK and press the center navigation button.
Polyurea
(PosiTector 200 D probes only)
When checked, the Gage loads a pre-programmed calibration
adjustment optimized for measurement of polyurea coatings.
Cal Lock
When checked, the icon appears and the current calibration
adjustment is “locked” to prevent further user adjustments.
Cal Reset
Restores the gage back to factory calibration and range settings.
The icon will appear on the display.

Setup Menu
Setup Menu
Reset
Reset (soft reset) restores factory settings and returns the Gage to
a known condition. The following occurs:
- All batches, stored measurements, images, batch names and
screen captures are erased.
- All calibration and range adjustments are cleared and returned
to the Gage’s factory settings.
- Menu settings are returned to the following:
Memory = OFF
Graphics = ON
Cal Lock = OFF
Bluetooth = OFF
Display = None
Layers = 1
Layer Name = Layer 1
Layer Color = blue
Perform a more thorough Hard Reset by powering down the
Gage, waiting several seconds, then simultaneously holding both
the center and (+) buttons until the Reset symbol
appears. This returns the instrument to a known, “out-of-the-box”
condition. It performs the same function as a menu Reset with the
addition of:
- Bluetooth Pairing info is cleared.
- Menu settings are returned to the following:
Units = microns
Flip Display = Normal
White on Black = OFF
Language = English
NOTE:
Date, Time and WiFi are not affected by either Reset.
Battery Type = Alkaline
Backlight = Normal
USB Drive= ON
Auto Sync = OFF
Battery Type
Selects the type of batteries used in the Gage from a choice of
“Alkaline”, “Lithium” or “NiMH” (Nickel-metal hydride
rechargeable). If NiMH is selected, the Gage will trickle charge the
batteries while connected via USB to a PC or optional AC charger.
The battery state indicator icon is calibrated for the selected
battery type. No damage will occur if the wrong battery type is
selected.
NOTE:
DeFelsko recommends the use of eneloop (NiMH)
rechargeable batteries.

Advanced models only)
Graphics
(
When selected, the Gage displays a
graphical representation of the ultrasonic pulse as it travels through the coating
system.
As the probe is depressed and the
ultrasonic pulse travels through the
coating system, the pulse encounters
changes in density at the interfaces
between coating layers and between the
coating and the substrate.
These interfaces are depicted by a "peak". The greater the change
in density, the higher the peak. The more gradual the change in
density, the greater the width of the peak. For example, two coating
layers made of essentially the same material and "blended" would
result in a low, wide peak. Two materials of very different density
and a well-defined interface would result in a high, narrow peak.
The PosiTector 200 chooses the highest peak (single layer) or
peaks (multi-layer) within the Set Range. For example, if the
number of layers is set to 3, the three highest peaks would be
identified with small red triangles. The peak values are also
displayed numerically as thickness measurements.
NOTE:
The Graphics display can also be accessed using the
Set Range menu option.
Use the navigation Up (move left) and Down (move right) buttons
to highlight icons on the graphic display.
Zoom - Visually magnifies the waveform of the displayed
peaks for more visibility. Pressing the (+) or (-) button repeatedly
will increase/decrease the zoom.
Set Range - Press the (-) or (+) buttons to adjust the
Gage’s Lo or Hi measuring range. (see pg. 5
)
8
Cursor - The Cursor allows for further analysis of displayed
waveform. Use the (-)(+) buttons to move the green cursor line left
or right over the waveform. The thickness value is displayed at the
top right of the cursor line. This feature is particularly
useful in multi-layer applications where there are more than
3 distinct layers.
Screen Capture - Press to capture and save an image
copy of the current display. The last 10 screen captures are stored
in memory and can be accessed when connected to a computer.

Acoplante
Acoplante
El acoplante es necesario para propagar el ultrasonido en el
recubrimiento. El agua es un buen acoplante para revestimientos
lisos. Utilice el gel de glicol suministrado para revestimientos más
ásperos. Si bien es improbable que el acoplador dañe el acabado
o deje mancha en la superficie, le sugerimos que realice una
prueba sobre una muestra. Si la prueba indica daño en la
superficie, puede utilizar una pequeña cantidad de agua en lugar
del acoplante. Consulte la hoja de datos de seguridad del material
disponible en nuestro sitio Web. Contacte a su proveedor de
recubrimiento si sospecha que el acoplante puede dañar el
revestimiento. También pueden utilizarse otros líquidos como el
jabón líquido.
PosiTector 200 - Fundamento de Operación
Las sondas PosiTector 200 emiten un pulso de sonido de alta
frecuencia que viaja por el revestimiento a través de un gel
acoplante y se refleja en CUALQUIER superficie que tenga
densidad diferente. Las lecturas de espesor de recubrimiento se
obtienen midiendo el tiempo que necesita la señal ultrasónica para
propagarse desde la sonda a la superficie de recubrimiento o
sustrato y regresar. El tiempo de transmisión se divide en dos y
se multiplica por la velocidad del sonido en el recubrimiento y así
obtener el espesor del recubrimiento.
El PosiTector 200

Calibración, Verificación y Ajuste
Calibración, Verificación y Ajuste
Para garantizar la mayor exactitud, siga estos tres pasos...
1.Calibración - realizada por el fabricante o por un laboratorio
cualificado. Todas las sondas incluyen Certificado de
Calibración.
2.Verificación de precisión - es realizada por el usuario
midiendo sobre patrones de referencia de espesor como las
laminillas de plástico incluidas o los patrones de espesor de
recubrimiento opcionales.
3.Adjuste - a un espesor conocido.
Calibración
La calibración es el proceso controlado y documentado de
medición de patrones de calibración trazables y la verificación de
los resultados para confirmar que estos se encuentran dentro del
nivel de precisión establecido del medidor. El proceso de
calibración generalmente lo realiza el fabricante del medidor o un
laboratorio de calibración certificado en un entorno controlado y
siguiendo un proceso documentado.
