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 body (Standard or Advanced) and probe (RTR-H or RTR-P).

PosiTector RTR-P models also measure peak density (Pd). Advanced RTR-P models generate 2D/3D images and SDF Surface Data Files.

A surface cleaned by abrasive blast is best described using two measured parameters: peak height and peak density.

Peak Height

H – the average of the maximum peak-to-valley distances obtained by measuring the thickness of the replica tape

HL – a more accurate peak-to-valley height measurement adjusted for tape non-linearity without the need to average 2 or more replicas. This method has the additional benefit of being able to extend the range of each grade of replica tape. See Linearize

Peak Density (RTR P only) Pd – the number of peaks per square millimeter or square inch. See Peak Density

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.

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.

With the Gage powered down...

  1. Clean the probe with the included cleaning card.
  2. Power-up the Gage by pressing the center navigation button.
  3. Zero the probe.
  4. Measure the included check shim to verify accuracy.
  5. Measure the burnished replica tape.

Plastic Lens Shield

The PosiTector display 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 or debris. Replacements can be purchased.

Probes

When powered-up the PosiTector automatically determines what type of 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 new probe. NOTE: It is not necessary to power-down the gage when interchanging probes.

Certification

PosiTector RTR 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.

Why is surface profile measurement important?

Steel surfaces are frequently cleaned by abrasive impact prior to the application of protective coatings. The resultant surface profile must be accurately assessed to ensure compliance with job or contract specifications. In the protective coatings industry, replica tape is widely used for quantifying surface profile.

Peak height and peak density are important factors in the performance of applied protective coatings. Low values may reduce coating bond strength (adhesion). High values may cause peaks to receive insufficient coverage and possibly rust prematurely and for the surface to be insufficiently wetted.

The figure below is a simplified example of why BOTH peak height AND peak density are important to the understanding of coating performance. The two surfaces have different geometries yet their height measurements are the same. Peak density measurements give a clearer picture of the surface available for bonding.

Both surfaces have the same measured peak-to-valley height. A second important measurable parameter, peak density, helps explain why coatings bond differently to each surface.

For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.

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.

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. Press-O-Film is available in Coarse (C) and X-Coarse (XC) grades to accommodate measurements in different profile ranges.

Optical Grade Press-O-Film Replica Tape
For improved optical resolution and to reduce optical artifacts (see below tape comparison), this special grade of replica tape is available for use with the PosiTector RTR-P. It provides higher quality SDF surface data files than conventional Press-O-Film replica tape. It is available in both Coarse (C) and X-Coarse (XC).

How to Measure

  1. Prepare the test surface
  2. Burnish the replica tape
  3. Prepare the Gage
  4. Measure

Prepare the test surface

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.

NOTE: Ensuring a clean surface is especially important when using the PosiTector RTR-P to measure peak density (Pd) and generate surface images.

Burnish the replica tape (create a replica)

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. 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 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

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.

NOTE: Cleaning the anvils is especially important when using the PosiTector RTR-P to measure peak density (Pd) and generate surface images. If the cleaning card is damp, wait for the anvils to dry before measuring.

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.

Ensure the correct grade of replica tape, C or XC, is displayed in the upper left corner of the LCD.

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.

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.

PosiTector RTR-H models

  1. Ensure tape is properly positioned.
  2. Firmly press both probe buttons simultaneously and hold until the Gage beeps and the surface profile height (HL) measurement is displayed. The tape can now be safely removed.

PosiTector RTR-P models
It is important to clean the anvils before each measurement when obtaining peak density (Pd) and generating surface images.

  1. Ensure tape is properly positioned.
  2. 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 the 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.
  3. The surface profile height (HL) measurement is immediately displayed.  The tape can now be removed.  An hour glass will display while peak density (Pd) and the associated 2D/3D images are being generated.

NOTE: Optical Grade Replica Tape provides higher quality SDF surface data files than conventional Press-O-Film replica tape. This special grade of tape recommended when taking measurements which will be exported as SDF images.

Cleaning the probe opening (anvils)

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 or a verification of accuracy. 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 cleaning card can also be used to clean the surfaces of analog spring micrometers. Replacement cards are available from your dealer.

NOTE: Cleaning the anvils is especially important when using the PosiTector RTR-P to measure peak density (Pd) and generate surface images.

Example of a 2D surface image taken with a PosiTector RTR-P Advanced before and after cleaning the anvils with the cleaning card.

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 and that the probe has been zeroed.

Verify 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 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 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 incompressible polyester film. Therefore plastic shims intended for other instruments such as coating thickness gages will not be measured properly.

Verify the peak density measuring system (RTR-P models only)
Place the Peak Density Check Tape into the probe opening. The peak density (Pd) result should be within tolerance specified on the tape. Ignore the peak height (H) result. If not, the Gage may need to be returned to your dealer for service..

Menu Operation

Gage functions are menu controlled. To access the Menu, power-up the Gage, then press the center navigation button.

Below is a sample menu for a PosiTector RTR H Advanced model:

NOTE: The center button is purposely recessed to help eliminate unintentional powering-up of the Gage.

Cal Settings Menu

Zero

The probe should be zeroed regularly to ensure best accuracy. While 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 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.

SHORTCUT:
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.

No Tape

(RTR-P only)

When selected the gage instructs the probe to take a picture and store this image as a reference. This image is used with subsequent measurements to compensate for irregularities in the optical path within the probe. This operation is only required if the generated images can not be cleaned up by cleaning the anvils with the cleaning card.

Tape Grade

Selects a replica tape grade. Required when Linearize mode (HL) is ON.
C - Coarse
XC - X-Coarse (default)

NOTE: 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 HL. When Linearize mode is OFF, the PosiTector RTR will measure all four grades of replica tape just like a conventional spring micrometer.

Linearize

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 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 - 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 HL that 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 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.

Setup Menu

Reset

Reset (soft reset) restores factory settings and returns the instrument to a known condition. The following occurs:

Memory = OFF Bluetooth = OFF Tape Grade = XC
Statisitics = OFF WiFi = OFF Linearize = ON
Peak Density* = On 2D* = OFF 3D* = OFF
Memory Display = None * PosiTector RTR-P models only

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:

Units = microns Battery Type = Alkaline
Flip Display = Normal Backlight = Normal
White on Black = OFF USB Drive = ON
Language = English Auto Sync = OFF
Sound = ON

Note: Date, Time and WiFi settings are not affected by either Reset.

Gage Info

Displays the gage body/probe details including serial numbers, PosiSoft.net registration key,remaining memory capacity for storage of readings, date and time and software packages.

For security purposes, the registration key is required to add the Gage to your PosiSoft.net account.

Peak Density

(RTR-P only)

When selected, the Gage will measure and display peak density (Pd), the number of peaks per unit area.

The PosiTector RTR-P projects light through the replica tape and captures a two-dimensional black and white image.

Peak density be determined by simply counting the bright spots on the image. The intensity of light that passes through the replica tape is inversely proportional to the thickness of the compressed foam. The below photograph of a back-lit piece of replica tape reveals light areas of higher compression (peaks) and dark areas of lower compression (valleys).

2D

(RTR-P Advanced models only)

Displays a two-dimensional (2D) black and white image of the replicated surface.  When Memory is on, this thumbnail image is stored with each reading for inclusion into inspection reports.

(RTR-P Advanced models only)

Displays a low-resolution color three-dimensional (3D) image of the replicated surface.  When Memory is on, this thumbnail image is stored with each reading for inclusion into inspection reports.

NOTE: Press the Up navigation button to scroll between 2D and 3D images if the image does not automatically appear on the display.

Save SDF

(RTR-P Advanced models only)

Stores a Surface Data File (SDF) to the USB Drive. This provides a means to perform a more detailed analysis of the surface using third party image rendering/analysis software such as Gwyddion or MountainsMap. Select Save SDF within the Memory menu. A progress bar will appear while the SDF is saved (approximately 2 minutes).

Only a single SDF can be stored at a time. Each saved image overwrites the previous one. The SDF can be accessed when connected to a computer (see USB Drive). The SDF is stored in the root directory named with the format: rtr_{datetime}.sdf

NOTE: Cleaning the anvils prior to measurement is especially important when using the PosiTector RTR-P to generate surface images.

Optical Grade Replica Tape provides higher quality SDF surface data files than conventional Press-O-Film replica tape. This special grade of tape is recommended when taking measurements which will be exported as SDF images.

Below is an example of a PosiTector generated SDF opened in Gwyddion - a free and open source software image rendering software. www.gwyddion.net
