Introduction
The osiTector RTR 3D Replica Tape Reader is a hand-held
electronic instrument that measures burnished Testex Press-O-
FilmTM replica tape and uses a light intensity versus thickness
algorithm to produce three-dimensional (3D) images of the replicated
surface. Images generated within the gage are analyzed to produce
2D and 3D parameters that represent specific characteristics of a
surface.
To ensure best accuracy, the user will be prompted to zero
the probe every time the Gage is powered-up. It is therefore good
practice to clean the probe regularly with the included cleaning card
and microfiber cloth. Cleaning is best performed when the Gage is
powered down.
NOTE:
With the Gage powered down...
1. Clean the probe with included cleaning card and microfiber
cloth (pg. 7).
2. Power-up Gage by pressing the center button.
3. Zero the probe (pg. 8).
4. Verify Gage accuracy (pg. 7).
5. Measure the burnished replica tape (pg. 4).

When powered-up, the osiTector 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 osiTector 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
ress-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 mils) incompressible polyester film. When
compressed against a surface, the foam collapses and acquires an
accurate impression, or reverse replica, of the surface.
Several grades of replica tape are available:
Tape Grade H Range 2D/3D Range Order Code
Coarse (C) 20 to 64 µm
0.8 to 2.5 mils ---------- R-PRESS
X-Coarse (XC) 40 to 115 µm
1.5 to 4.5 mils ---------- R-PRESSX
Optical Grade
Coarse (C)
20 to 64 µm
0.8 to 2.5 mils ---------- R-PRESSOG
Optical Grade
X-Coarse (XC)
40 to 115 µm
1.5 to 4.5 mils
10 to 115 µm
0.4 to 4.5 mils R-PRESSXOG
If only the maximum peak-to-valley height is needed, then
conventional Coarse or X-Coarse can be used. Placing the
compressed tape (replica) into the osiTector RTR 3D gives a
measure of the average maximum peak-to-valley height (H) of the
surface roughness profile. The Gage automatically subtracts the
thickness of the polyester substrate from all measurements. Press-
O-Film is available in Coarse (C) and X-Coarse (XC) grades to
accommodate measurements in different profile ranges.

Optical Grade ress-O-Film Replica Tape for 2D/3D Measurements:
When measuring 2D and 3D parameters, it is recommended to use
optical grade Press-O-Film. Optical grade tape provides higher
resolution images than conventional Press-O-Film replica tape. It is
available in both Coarse (C) and X-Coarse (XC). Only X-Coarse
(XC) can be used when measuring 2D and 3D parameters.
Operating rinciple
The osiTector RTR 3D uses two measurement principles: a digital
micrometer to measure the overall height of the burnished replica
tape, and an optical system that projects light through the replica tape
and captures a two-dimensional black and white image.
The digital micrometer is used to measure the overall thickness of the
burnished replica tape. After subtracting the thickness of the
incompressible polyester film and linearizing the result (pg.9), this
thickness corresponds to the average maximum peak-to-valley height
(H).
It is known that replica tape transmits light proportionally to the degree
to which it is compressed. Peaks in the surface profile compress the
replica tape and result in bright spots, while valleys compress the
replica tape less, and result in dark spots. By recording the amount
of light transmission at each point on the burnished replica tape, a
precise 3D map of the surface can be generated. 2D and 3D surface
profile parameters can be measured.
The osiTector RTR 3D uses a light intensity versus thickness
algorithm to produce three dimensional (3D) images of the replicated
surface burnished using Replica Tape. The image sensor produces a
1024 x 1024 pixel image that represents an approximate 3.8 mm x
3.8 mm image area. Images generated within the gage are analyzed
to produce 2D and 3D parameters that represent specific
characteristics of a surface.

the osiTector RTR 3D to measure 2D and 3D parameters (pg. 13)
or generating SDF files (pg. 12) for post processing.
NOTE:
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.
2. Burnish the replica tape (create a replica)
Select the appropriate grade of replica tape based on the target pro-
file. 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 the surface. Press the adhe-
sive-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 or acrylic burnishing ball. Apply
sufficient pressure in a circular and x-y rubbing
motion to produce a
replica with a uniform
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.
It is important to clean the anvils and camera lens before
each measurement of 2D and 3D parameters or generating SDF files.
(pg. 7).
NOTE:
3. repare the Gage
The acrylic burnishing ball is recommended when obtaining
2D/3D parameters or generating SDF files.
NOTE:
Power-up the Gage by pressing the 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.
Ensure the correct grade of replica tape, C or XC, is
displayed in the upper left corner of the display (pg. 8).
4. Measure
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, move the tape to the back of the probe and align
the two dots (printed on replica tape) with arrows on both sides of the
measurement opening.
Align dots with arrows on probe
During measurement, a constant anvil pressure is applied to the
replica tape regardless of how hard the two buttons are pressed.
1. a) Firmly press both probe buttons simultaneously and hold
until the Gage beeps and the arrows point outward.
b) Remove your fingers from the tape and release both
probe buttons (do not hold or remove tape from gage).
c) Hold the gage steady while the probe measures the
compressed foam until the following graphic
disappears.
Several images of the foam surface are captured during
each measurement. Image blurring will occur if the tape is
touched or removed during this time.

2. The surface profile height (HL) measurement is immediately
displayed. The tape can now be removed. An hour glass will
display while 2D and 3D parameters are calculated.
Cleaning the probe opening (anvils)
The probe contains two measuring surfaces (anvils) and a camera
lens that can become contaminated with dust particles and residual
tape adhesive. It is therefore recommended to clean the probe
regularly with the included cleaning card and microfiber cloth. Cleaning
is essential prior to performing a probe zero (pg. 8) or a verification of
accuracy (below). 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 pressing both probe buttons. Then insert the included
microfiber cloth and gently wipe the surfaces of the anvils several
times by sliding the cloth back and forth with the probe buttons
pressed.
The cleaning card can also be used to clean the surfaces of analog
spring micrometers. Replacement cards and microfiber cloths are
available.
Cleaning the anvils is especially important when using the
osiTector RTR 3D to measure 2D and 3D parameters or generating
SDF files.
NOTE:
Calibration & Verification of Accuracy
Calibration
Gage calibration is typically performed by the manufacturer or
accredited lab. All probes include a Certificate of Calibration.
Verification of Accuracy
Ensure that the probe has been cleaned with the included cleaning
card (above) and that the probe has been zeroed (pg. 8).
Verify accuracy of the digital micrometer measuring system
Place the osiTector RTR Check Shim into the probe 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 for service.
The check shim is specifically intended for all osiTector RTR
probes. The Gage is designed to measure burnished replica tape

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. 7)
before performing a probe zero.

µm (2 mils) 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.
Verify the optical measuring system
Place the Peak Density Check Tape into the probe opening. The peak
density (Spd) result should be within tolerance specified on the tape.
If not, the Gage may need to be returned to your dealer for service.

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.
SHORTCUT:
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
osiTector
RTR 3D will
automatically do when measuring HL. When Linearize mode is

Linearize
nWhen the Linearize box IS checked, the osiTector RTR 3D
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 mils) of incompressible
polyester film. Ensure the proper tape grade, C or XC, has been
selected (pg. 8) and appears in the upper left corner of the display.
nWhen the Linearize box is NOT checked, the osiTector RTR 3D
displays a height value of H comparable to the value an analog
spring micrometer would display after the 50.8 µm (2 mils) 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.
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.
OFF, the
osiTector RTR 3D will measure all grades of replica
tape just like a conventional spring micrometer.

Analysis Setup Menu
2D parameters are calculated from a virtual ‘trace’ across the image
area. When the Orientation (pg. 15) is set to Horizontal X or Vertical
Y directions, the Evaluation Length is equal to 3.8 mm, minus double
the length of the selected discard filter. When the Orientation is set to
Diagonal XY or Diagonal YX directions, the Evaluation Length is equal
to 5.4 mm, minus double the length of the selected discard filter.
The 2D Parameters Menu allows the operator to select 2D
analysis parameters to be displayed by the gage (a maximum of 6
parameters can be selected from the 2D and 3D Parameter lists).
Ra (default) Roughness average: arithmetic average of the
absolute values of the profile height deviations within the evaluation
length measured from the mean line
Rq RMS roughness: root mean square average of the profile
heights within the evaluation length measured from the mean line
Rz Average maximum height of the profile: arithmetic average
of the successive values of the maximum peak to deepest valley
within each sampling interval calculated over the evaluation length.
The length of the sampling interval is equal to the cutoff length λc (pg.
15) and the number of sampling intervals is the number of whole cutoff
lengths λc that can fit within the Evaluation Length.
Rp Maximum profile peak height: the distance between the
highest point of the profile and the mean line within the evaluation
length
Rv Maximum profile valley depth: the distance between the
deepest valley and the mean line within the evaluation length
Rt Total profile height: the distance between the highest peak
and the deepest valley within the evaluation length
Rpc eak count: number of peaks per unit length within the
evaluation length
Rpc Boundary C1: defines the boundary lines located equidistant
above and below the profile mean line. A Peak is counted after the
trace goes below the lower boundary line and above the upper
boundary line. The default is 0.5 µm.
2D arameters

3D parameters are calculated across the image area. When
calculating 3D parameters, an evaluation area is determined by
removing an area around the outside edge of the image area equal
to the width of the discard length.
The 3D Parameter Menu allows the operator to select 3D analysis
parameters to be displayed by the gage (a maximum of 6 parameters
can be selected from the 2D and 3D Parameter lists).
H (default) Average maximum peak-to-valley height:
the distance between the anvils minus the 50.8 µm (2 mils) of
incompressible film. When selected an optional linearization can be
performed by selecting the linearization checkbox in the Cal Settings
Menu (see pg. 9)
Spd (default) Areal peak density: the number of peaks per unit
area (formerly known as Pd).
Sa (default) Average roughness: the arithmetic average of the
absolute values of the measured height deviations from the mean
surface taken within the evaluation area.
Sq Root mean square roughness: the root mean square average
of the measured height deviations from the mean surface taken within
the evaluation area.
Sz Maximum area peak-to-valley height: the vertical distance
between the maximum peak height and the maximum valley depth.
Commonly referred to as St.
Sp Maximum area peak height: the maximum height in the
evaluation area with respect to the mean surface.
Sv Maximum valley depth: the absolute value of the minimum
height in the evaluation area with respect to the mean surface.
Filter Settings
To optimize the analysis for a specific application, filters may be
applied to the raw image to remove undesirable profile characteristics
prior to calculating the 2D and 3D parameters. The short wavelength
(λs) Gaussian filter attenuates features that have a wavelength
shorter than the selected size. The long wavelength cutoff (λc)

A side effect of the long wavelength cutoff (λc) filter is that values near
the edge of the evaluation length or area are skewed. To prevent
these skewed values from affecting 2D and 3D parameter
calculations, the values near the edges of the evaluation are
discarded. The Discard length is calculated from the long wavelength
cutoff (λc) selected.
The following discard selec ions are available:
Discard none
Discard ½ (default)
Discard 1
2D Orientation
2D parameters are calculated from a virtual ‘trace’ across the image
area. By default, this trace is in the Horizontal X direction, parallel to
the long axis of the replica tape. This orientation can be changed if
desired:
Horiz X (Horizontal X) (default)
Vert Y (Vertical Y)
