PosiTector® SmartLink PosiTector RTR Replica Tape Reader probes measure burnished Testex Press-O-Film replica tape to produce peak-to-valley surface profile height measurements. This instruction manual specifically covers use with PosiTector SmartLink. The PosiTector SmartLink and free mobile app allow you to wirelessly connect a wide selection of PosiTector probes to your smart device. Take full advantage of your device's keyboard, microphone, camera, internet data connection, etc. to simplify and enhance your measurement inspection process.
The PosiTector SmartLink measurement solution consists of a PosiTector App, PosiTector SmartLink device and compatible PosiTector probe. In addition to the PosiTector RTR-H, compatible probes include the PosiTector SPG (surface profile), 6000 (coating thickness) and DPM (environmental conditions). Why is Measurement Important? Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely. The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications. Press-O-Film Replica Tape Placing the compressed tape (replica) into the PosiTector RTR-H probe gives a measure of the average maximum peak-to-valley height of the surface roughness profile. The polyester substrate is automatically subracted from all measurements.  The PosiTector SmartLink powers-up when the LED button is pressed. To preserve battery life, the PosiTector SmartLink powers-down after 5 minutes of no activity. Alternatively, press and hold the LED button until it turns red and shuts off (approximately 5 seconds). All probe settings and calibration adjustments are retained within the PosiTector SmartLink, stored measurement data is retained within the smart device (cell phone, tablet). Measure To ensure best accuracy, the probe should be zeroed before each use. It is therefore a good idea to clean the probe regularly with the included cleaning card. Cleaning is best performed when the PosiTector SmartLink is powered down. 1. Clean the probe with the include cleaning card 2. Wirelessly Connect the PosiTector probe to the smart device using the PosiTector App 3. Zero the probe 4. Measure the included check shim to verify accuracy 5. Measure the burnished replica tape See How to Measure for more detailed measuring instructions. The PosiTector App connects a PosiTector SmartLink to your smart device enabling you to use PosiTector 6000, DPM, SPG or RTR-H probes on your device without the need for a conventional gage body. Screen fonts, brightness and displayed language are inherited from your smart device settings. Currently, the PosiTector App has language support for English, Spanish, French, German, Chinese and Korean. Screen orientation is fixed to portrait only, rotation to landscape is not supported. Stored batch readings, images and notes are all stored in the PosiTector App (on your smart device). The number of stored batch readings is only limited by the memory available on your smart device. If the application is removed or a menu Reset is performed, all stored readings and associated data is permanently erased.
Wirelessly Connecting the PosiTector App to the PosiTector RTR-H probe 1. Power-up the PosiTector SmartLink and connected RTR-H probe by pressing the LED button. The button will blink blue. 2. Select the PosiTector SmartLink App icon on your smart device. 3. Select Continue. A list of available PosiTector probes (listed by connected probe type and serial number) will be displayed. Select the desired PosiTector SmartLink to connect. The LED button on the PosiTector SmartLink will illuminate solid blue when successfully connected.

The PosiTector SmartLink acts as a relay between the PosiTector probe and PosiTector App using wireless Bluetooth Smart (BLE Bluetooth Low Energy). No pairing required! Auto-pairing Bluetooth connection works up to 10m (30 feet) away. Information specific to currently selected modes (i.e. Scan mode, Fast mode, etc.) and user calibration adjustments (specific to each probe) are retained within the PosiTector SmartLink. This allows for seamless switching between smart devices (phone and tablet).
Connect a Probe When powered-up the PosiTector SmartLink automatically determines what type of probe is attached and does a self-check. The probe type, model and serial number display are displayed when found within the app's Search screen.

1. Prepare the test surface Prepare the test surface
Burnish the replica tape (create a replica) 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 probe Power-up the PosiTector SmartLink by pressing the LED button. Zero the probe by simultaneously pressing and holding both probe buttons firmly until 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, Coarse or X-Coarse, is displayed in the upper left corner of the measurement area. Measure
To position the tape, move The TestexTM Press-O-FilmTM replica 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 TestexTM Press-O-FilmTM replica 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 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 PosiTector RTR-H probe automatically subtracts the 50.8 um (2 mil) of incompressible polyester film. No further adjustments are required.
Calibration and Verification of Accuracy Calibration PosiTector RTR probes ship with a Certificate of Calibration showing traceability to a National Metrology Institution. For organizations with re-certification requirements, probes 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 DeFelsko’s product knowledge, data and customer feedback, a one year calibration interval from either the last date of calibration, date of purchase, or date of receipt is a typical starting point. Written Calibration Procedures are available online at no charge. http://www.defelsko.com/quality/calibration_procedures.htm Verification Place the check shim into the measurement opening. The average of several readings should be within the combined tolerance of both the probe and the shim. If not, the probe may need to be returned to your dealer for service. The check shim is specifically intended for the PosiTector RTR-H. The probe is designed to measure burnished replica tape within a limited measuring range and automatically subtracts 50.8 um (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.
PosiTector RTR-H functions are menu controlled. Access them by selecting Menu in the upper right of the PosiTector App display.
The Main Menu contains the following sub-menu's... Select Exit to close the menu. Zero 1. Select Zero from the Cal Settings menu 2. Simultaneously press and hold both probe buttons firmly until 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 "0" displays (arrows do not display as in above). This can be performed from the main measurement screen without having to access the menu. Reset Current Cal Tape Grade Coarse
Linearize mode HL 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 um (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 um (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-H displays a height value of H comparable to the value an analog spring micrometer would display after the 50.8 um (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-H 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 um (2 mil) of incompressible polyester substrate. Ensure the proper tape grade, Coarse or X-Coarse, 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, a more suitable tape grade will be suggested to perform the measurement. The PosiTector App uses your smart device's storage for recording measurement data. Stored measurements can be reviewed on-screen or shared via email (PDF, CSV). Measurements are date and time-stamped (using date/time from smart device). The following options appear within the Memory menu. Additional options may appear depending on the connected PosiTector SmartLink and probe type.
