Introduction
Introduction
The PosiTector Replica Tape Reader (RTR) is a hand-held
electronic instrument that measures burnished Testex Press-O-
FilmT replica tape to produce peak-to-valley surface profile height
measurements. It consists of a body (Standard or Advanced) and
probe.
This Quick Guide summarizes the basic functions of the Gage.

Menu Operation
Menu Operation
Gage functions are menu controlled. To access the enu, power-
up the Gage, then press the center navigation button.
NOTE:
To ensure best accuracy, the user will be required to zero
the probe every time the Gage is powered-up. It is therefore a
good idea to clean the probe regularly with the included cleaning
card. Cleaning is best performed when the Gage is powered down.
NOTE:
With the Gage powered down...
1. Clean the probe with the included cleaning card. (pg. 5)
2. Power-up Gage by pressing the center navigation button.
3. Zero the probe. (pg. 6)
4. easure the included check shim to verify accuracy (pg. 5)
5. easure the burnished replica tape (pg. 4)

Probes
Probes
To disconnect a probe from a body, power-down the
Gage and slide 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 which probe is attached and does a
self-check.
Press-O-Film Replica Tape

Additionally, the PosiTector accepts a number of probe types
including magnetic, eddy current and ultrasonic coating thickness,
surface profile, environmental and ultrasonic wall thickness
probes.
For the latest information on probe interchangeability, see
www.defelsko.com/probes
Press-O-Film provides a simple way to obtain an impression of a
surface for analysis. It consists of a layer of crushable plastic micro
foam affixed to a 50.8 µm (2 mil) incompress-
ible polyester film. When compressed against
a roughened surface, the foam collapses and
acquires an accurate impression, or reverse
replica, of the surface. It is available in a number of grades to
accommodate measurements in different profile ranges.
Placing the compressed tape (replica) into the PosiTector RTR
gives a measure of the average maximum peak-to-valley height of
the surface roughness profile. The Gage automatically subtracts
the thickness of the polyester substrate from all measurements.

How to Measure
How to Measure
Prepare the test surface
Burnish the replica tape (create a replica)
1. Prepare the test surface
2. Burnish the replica tape
3. Prepare the Gage
4. easure
Locate a representative site for measurement.
Clean the surface to be tested. DeFelsko
recommends the use of the included putty to
remove dust, debris, or residual blast media from
the surface. Firmly press the putty onto the surface
using your fingers, and remove.
Select the appropriate grade of replica tape based on the target
profile. See tape instructions for assistance.
Pull a single adhesive-backed replica tape free of its release
paper. A “bull’s eye” circle of paper should remain on the release
paper (it is not used for measurement).
Apply replica tape to blasted surface. Press the
adhesive-backed ends of the paper to hold it firmly
in place during the burnishing process.
Firmly compress replica film using the rounded end
of the included stainless steel burnishing tool.
Apply sufficient pressure in a circular and x-y
rubbing motion to produce a replica with a uniform
pebble grain appearance. It normally takes 30 to 60
seconds to fully compress all parts of the film on
most surfaces. In general, too much compression is
safer than too little. After burnishing is complete, remove the
replica tape from the surface.

Prepare the Gage
Measure
With the Gage powered-down, clean the measurement surfaces
using the included cleaning card. Swipe the card through the
opening a few times while firmly pressing both probe buttons to
remove dust particles and residual tape adhesive.
Power-up the Gage by pressing the center navigation
button. An image appears indicating that the probe
requires zeroing.
Simultaneously press and hold both probe buttons firmly until the
Gage beeps and the arrows point outward. Do not place anything
in the measurement opening during this procedure.
easure the included check shim to verify accuracy (pg. 5).
Ensure the correct grade of replica tape, C or XC, is displayed in
the upper left corner of the LCD (pg. 6).
Insert the burnished replica tape into the
measurement opening. Ensure the tape is
properly positioned so that the burnished region
is centered within the opening in the probe with
the adhesive (sticky) side down.
To position the tape, align the two dots (printed on replica tape)
with arrows on both sides of the measurement opening.
Align dots with
arrows on probe
If you are using older tape that does not have the printed dots,
simply align by centering the tape within the measurement
opening.
Once positioned, firmly press both probe buttons simultaneously
and hold until the Gage beeps and the measurement is displayed.
During measurement, a constant anvil pressure is applied to the
replica tape regardless of how hard the two buttons are pressed.
The Gage automatically subtracts the 50.8 µm (2 mil) of
incompressible polyester film. No further adjustments are required.

Verification of Accuracy
Gage accuracy is verified using the included check shim.
Ensure that the probe has been cleaned with the included
cleaning card (above) and that the probe has been zeroed (pg. 6).
Place the check shim into the measurement opening. The
average of several measurements should be within the combined
tolerance of both the Gage and the shim. If not, the Gage may
need to be returned to your dealer for service.
The check shim is specifically intended for the PosiTector RTR.
The Gage is designed to measure burnished replica tape within a
limited measuring range and automatically subtracts 50.8 µm (2 mil)
from height measurements to account for the incompressible
polyester film. Therefore plastic shims intended for other
instruments such as coating thickness gages will not be measured
properly.
Calibration
Gage calibration is typically performed by the manufacturer or
accredited lab. All probes include a Certificate of Calibration.
The probe contains two measuring surfaces that can become
contaminated with dust particles and residual tape adhesive. It is
therefore a good idea to clean the probe regularly with the included
cleaning card. Cleaning is essential prior to performing a probe
zero (pg. 6) or a verification of accuracy (pg. 5). It is best
performed when the Gage is powered down.
With the Gage powered-down, swipe the card through the opening
a few times while firmly pressing both probe buttons.
The card can also be used to clean the surfaces of analog spring
micrometers. Replacement cards are available from your dealer.

The probe should be zeroed regularly to ensure best accuracy.
The user will be required to zero the probe every time the Gage is
powered-up. The Zero menu item allows the procedure to be
performed at more regular intervals. It is particularly useful during
long measurement sessions.
Clean the probe with the included cleaning card (pg. 5) before
performing a probe zero.
1. Select Zero from the Cal Settings menu
2. Simultaneously press and hold both probe buttons firmly until
the Gage beeps and the arrows point outward. Do not place
anything in the measurement opening during this procedure.
Zero
Selects a replica tape grade. Required when Linearize mode (HL)
is ON.
C - Course
XC - Extra Course (default)
Simultaneously press and hold both probe buttons
firmly until the Gage beeps and displays “0”. This can be
performed from the main measurement screen without having to
access the menu.
Coarse inus and X-Coarse Plus grades are not
supported in Linearize mode since the only function of these two
grades is to improve upon the accuracy of C tape at its low end
and XC tape at its high end, something the PosiTector RTR will
automatically do when measuring HL. When Linearize mode is
OFF, the PosiTector RTR will measure all four grades of replica
tape just like a conventional spring micrometer.
NOTE:
SHORTCUT:
6

This is the default measurement mode. Linearize mode is ON
when this box is ticked and the "HL" appears on the display.
An undesirable characteristic of replica tape is that measurements
made with analog spring micrometers are most accurate near the
middle of each grade's range and least accurate at the outer ends
of each grade's range. That is why two other grades, Coarse
inus and X-Coarse Plus, are used to check and, if necessary,
adjust measurements at the lower and upper ends of the primary
range of 20 - 115 µm (0.8 - 4.5 mils).
Inside the primary range, the upper end of Coarse grade’s range
and the lower end of X-Coarse grade’s range share a 38 - 64 µm
(1.5 - 2.5 mil) "overlap" region. Current Testex instructions
describe a relatively complicated and time consuming procedure
(the average of one reading using Coarse grade and one reading
using X-Coarse grade) that is used to knit the Coarse and
X-Coarse sub-ranges together to achieve reasonably accurate
readings over the primary range. This method is a compromise
between accuracy and ease of use.
When the Linearize box is NOT ticked, the PosiTector RTR
displays a height value of H comparable to the value an analog
spring micrometer would display after the 50.8 µm (2 mil) of
incompressible polyester substrate has been subtracted. In other
words, it is the average of the maximum peak-to-valley distances
obtained by measuring the thickness of the replica tape without
any correction.
When the Linearize box IS ticked, the PosiTector RTR displays
a more accurate peak-to-valley height measurement HLthat has
been adjusted for the non-linearity of replica tape. There is no
need to average 2 or more replicas from different grades of tape
AND there is no need to subtract the 50.8 µm (2 mil) of
incompressible polyester substrate. Ensure the proper tape
grade, C or XC, has been selected (pg. 6) and appears in the
upper left corner of the display.

During measurement, if the linearized measurement falls outside
of the selected tape grade's range, the Gage will suggest a more
suitable tape grade to perform the measurement.
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.

Press-O-Film ofrece un método simple para obtener una
impresión de una superficie para su análisis. Se trata de una
lámina de plástico recubierta de microespuma
plástica deformable adherida a una película
de 50.8 µm (2 mil) incompresible de poliéster.
Al comprimirse contra una superficie rugosa,
la espuma adquirirá una impresión precisa o réplica inversa de la
superficie. Se vende en diferentes grados para acomodar las
medidas a diferentes rangos de perfil.
Al colocar la cinta comprimida (réplica) en el PosiTector RTR dará
una medida del promedio de la altura máxima entre pico y valle del
perfil rugoso de la superficie. El medidor sustraerá
automáticamente el espesor del sustrato de poliéster de todas las
mediciones.

1. Prepare la superficie del área de prueba
2. Perfile la cinta de réplica
3. Prepare el medidor
4. Realice la medición
Encuentre un lugar representativo para la medición.
Limpie la superficie que va a comprobar. DeFelsko
recomienda el empleo de la masilla suministrada
para retirar el polvo, la suciedad o la granalla
residual de la superficie. Presione con fuerza la
masilla sobre la superficie utilizando los dedos y
retírela.
Seleccione el grado apropiado de la cinta de réplica según el per-
fil deseado. Consulte las instrucciones de la cinta.
Coloque una cinta de réplica autoadhesiva retirando su papel pro-
tector. Un círculo de "ojo de buey" de papel deberá quedar en el
papel de protección (no se utiliza para la medición).
Aplique la cinta de réplica en la superficie. Presione
los extremos adhesivos del papel para sujetarlo
firmemente en su lugar durante el proceso de per-
filado.
Comprima firmemente la película de réplica
utilizando el extremo redondeado de la herramienta
de pulido de acero inoxidable. Aplique una presión
suficiente en círculo y frote en sentidos
transversales para producir una réplica con un
aspecto de grano uniforme. ormalmente se
requieren de 30 a 60 segundos para comprimir completamente
todas las partes de la película en la mayoría de las superficies. En
general, el exceso de compresión es más seguro que demasiado
poca. Una vez finalizado el perfilado retire la cinta de réplica de la
superficie.

XC) se muestra en la esquina superior izquierda de la pantalla LCD (pág.
6).
Inserte la cinta de réplica pulida en la ranura de
medición. Asegúrese de que la cinta esté
colocada correctamente para que el área pulida
esté centrada en la ranura en la sonda.
Para colocar la cinta, alinee los dos puntos (impresos en la cinta
de réplica) con las flechas en ambos lados de la ranura de

Comprobación e la precisión
La precisión del medidor se verificará utilizando la galga de
comprobación suministrada. Asegúrese de que la sonda se ha
limpiado con la tarjeta de limpieza (arriba) y que se ha puesto a
cero la sonda (Pág. 6).
Coloque la galga de comprobación en la ranura de medición. La
media de varias mediciones debería encontrarse entre las
tolerancias combinadas del medidor y la galga. Si no, deberá
devolver su medidor a su distribuidor para reparación.
La galga de comprobación está diseñada de manera especial
para el PosiTector RTR. El medidor está diseñado para medir el
perfil de anclaje de una cinta de réplica en un rango limitado y
automáticamente sustraerá 50.8 µm (2 mil) del perfil para contar
con la película de poliéster incompresible. Por lo tanto las
galgas de plástico destinadas a otros instrumentos tales como
medidores de espesor de recubrimiento no medirán
correctamente.
Calibración
El fabricante o un laboratorio acreditado realizará normalmente la
calibración del medidor. Todas las sondas incluyen Certificado de
Calibración.
La sonda tiene dos superficies de medición que pueden
contaminarse con partículas de polvo y adhesivo residual de la
cinta. Por lo tanto será deseable limpiar la sonda regularmente
con la tarjeta de limpieza incluida. La limpieza es esencial antes
de poner a cero la sonda (Pág. 6) o comprobar la precisión (Pág.
5). La limpieza se realizará mejor con el medidor apagado.
Con el medidor apagado, pase la tarjeta por la ranura un par de
veces mientras presiona firmemente los dos botones de la sonda.
