Introduction
The PosiTector Replica Tape Reader (RTR) is a hand-held
electronic instrument that measures burnished Testex Press-O-
FilmTM replica tape to produce peak-to-valley surface profile height
measurements. It consists of a PosiTector body (Standard or
Advanced) and probe.
This Quick Guide summarizes the basic functions of the Gage.
Download the full instruction manual at: defelsko.com/manuals
Quick Start
The PosiTector RTR powers-up when the center navigation
button is pressed. To preserve battery life, the Gage powers
down after approximately 5 minutes of no activity. All settings are
retained.
To ensure best accuracy, the user will be prompted 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.

Press-O-Film Replica Tape
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) incompressible 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
Coarse (C) and X-Coarse (XC) 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 film from all measurements.
Probes
When powered-up, the PosiTector automatically
determines which probe is attached and does a self-
check.
To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power-
down the Gage when switching probes.
The PosiTector gage body accepts a wide variety of
probe types including magnetic, eddy-current and
ultrasonic coating thickness, surface profile,
environmental, hardness, salt contamination and
ultrasonic wall thickness probes. See
www.defelsko.com/probes

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. Measure
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 tape to hold it firmly in place during the
burnishing process.
Firmly compress the foam 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. Excessively
hard rubbing should be avoided because the polyester film
could become distorted. It normally takes 30 to 60 seconds to
fully compress all parts of the foam on most surfaces. After
burnishing is complete, remove the replica tape from the surface.

Prepare the Gage
Measure
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.
Measure 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 gage display (pg. 6).
Insert the burnished replica tape into the
probe opening as far as it will go. Ensure
the tape is properly positioned so that the
burnished region is centered within the
opening 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
4
If you are using older tape that does not have the printed dots,
simply align by centering the tape within the measurement opening.
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.
1. Ensure tape is properly positioned.
2. Firmly press both probe buttons simultaneously and hold until
the Gage beeps and the surface profile height ( )
measurement is displayed. The tape can now be safely
removed.
With the Gage powered-down, clean the measurement surfaces
using the included cleaning card. Swipe the card through the
probe opening a few times while firmly pressing both probe
buttons to remove dust particles and residual tape adhesive.

3. The surface profile height ( ) measurement is immediately
displayed. The tape can now be removed.
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).
Cleaning is best performed when the Gage is powered off.
With the Gage powered-down, swipe the card through the probe
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.
Cleaning Card
erification of Accuracy
Calibration
Gage calibration is typically performed by the manufacturer or
accredited lab. All PosiTector RTR probes include a Certificate
of Calibration.
Calibration & erification of Accuracy
Ensure that the probe has been cleaned with the included cleaning
card (pg.5) and that the probe has been zeroed (pg. 6).
erify accuracy of the peak height measuring system
Place the PosiTector RTR Check Shim into the probe opening.
The average of several measurements should be within the com-
bined 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 all PosiTector RTR
probes. 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 incom-
pressible polyester film. Therefore plastic shims intended for other
instruments such as coating thickness gages will not be meas-
ured properly.

Tape Grade
Cal Settings Menu
The probe should be zeroed regularly to ensure best accuracy.
The user will be prompted 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.
Important: 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 ( L)
is ON.
C - Coarse
XC - Extra Coarse (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 Minus 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 L. When Linearize mode is
OFF, the PosiTector RTR will measure all grades of replica tape
just like a conventional spring micrometer.
NOTE:
S ORTCUT:

Linearize
This is the default measurement mode. Linearize mode is ON when
this box is ticked and the " L" 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 Minus
and X-Coarse Plus, are used to check and, if necessary, adjust
measurements at the lower and upper ends of the primary range of
20-115µm (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 comparable to the value an analog
spring micrometer would display after the 50.8 µm (2 mil) of
incompressible polyester film 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 Lthat 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 film. 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.

Selects the type of batteries used in the Gage from a choice of
“Alkaline”, “Lithium”or“NiM ” (Nickel-metal hydride rechargeable).
If NiM 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. DeFelsko
recommends the use of eneloop (NiM ) rechargeable batteries.

Para desconectar una sonda de un cuerpo apague el
medidor y deslice el conector de plástico de la sonda en
sentido horizontal fuera del cuerpo (siguiendo la flecha).
Invierta los pasos para conectar una nueva sonda.
Una vez encendido, el PosiTector determinará
automáticamente el tipo de sonda conectado y
realizará una comprobación automática.
Cinta de réplica Press-O-Film
Además, el PosiTector acepta varios tipos de sonda incluyendo
sondas magnéticas para espesores de recubrimiento y por
corrientes de Foucault, para perfiles de superficie, ultrasónicas
para espesores de pared y ambientales.
Para obtener la información más reciente sobre la compatibilidad
de la sonda consulte www.defelsko.com/probes
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.

Cómo medir
Preparación de la superficie de prueba
Creación de una réplica
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
perfil deseado. Consulte las instrucciones de la cinta.
Coloque una cinta de réplica autoadhesiva retirando su papel
protector. 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 perfilado.
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. Normalmente 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.

4
Preparación del medidor
Con el medidor apagado, limpie las superficies de medición
utilizando la tarjeta de limpieza facilitada. Deslice la tarjeta a
través de la ranura varias veces mientras presiona firmemente
los dos botones de la sonda para eliminar las partículas de polvo
y el adhesivo residual de la cinta.
Encienda el medidor pulsando el botón central. Aparecerá una
imagen que indica que la sonda requiere su puesta a cero.
Pulse y mantenga con firmeza simultáneamente ambos botones
de la sonda hasta que el medidor emita un pitido y las flechas
apunten hacia el exterior. No coloque nada en la ranura de
medición durante este procedimiento.
Mida la galga de comprobación suministrada para verificar la
exactitud (Pág. 5). Asegúrese de que el grado de la cinta de
réplica adecuado (C o 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 medición.
Alinee los puntos con
las flechas en la sonda
Si está utilizando una cinta antigua que no tiene los puntos impresos,
simplemente alinee centrando la cinta en la ranura de medición.
Una vez colocado, presione con firmeza simultáneamente los dos
botones de la sonda y mantenga la sonda hasta que el medidor
emita un pitido y muestre la medición. Durante la medición se
aplicará una presión constante en la cinta de réplica con
independencia de la aplicada en los botones. El medidor restará
automáticamente los 50.8 µm (2 mil) de la película incompresible de
poliéster. No se requieren ajustes adicionales.

Comprobación de 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.
La tarjeta también podrá utilizarse para limpiar las superficies de
micrómetros analógicos de muelle. Su distribuidor dispone de
tarjetas de recambio.
