More Information

Linearized Peak Height

Two grades of Testex™ Press-O-Film™ replica tape, “Coarse” and "X-Coarse", are available to span the primary range of surface profiles for the coatings and linings industry –– 20 to 115 µm / 0.8 to 4.5 mils.

An unfortunate characteristic of replica tape is that conventional spring micrometer measurements 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 (< 20 µm / 0.8 mils) and X-Coarse Plus (> 115 µm / 4.5 mils), are used to check and, if necessary, adjust measurements at the upper and lower ends of the primary range.

Inside the primary range, Coarse and X-Coarse tape share a 38 - 64 μm (1.5 - 2.5 mils) "overlap" region. Measurements with conventional micrometers require a complicated and time consuming procedure of averaging one reading using Coarse grade and one reading using X-Coarse grade to achieve reasonable accuracy.

With a single measurement, the PosiTector RTR H produces a more accurate peak-to-valley height measurement HL from Coarse or X-Coarse tapes that has been adjusted for their non-linearity. There is no need to average two 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. The advantages are a reduction in measurement uncertainty, inspector workload, likelihood of error, and the number of replicas needed by inspectors to assure accuracy.

The PosiTector RTR H can also display a height value (H) that is comparable to what conventional analog spring micrometers would display after the 50.8 μm / 2 mils of incompressible polyester film has been subtracted.

Procedure

Prepare

Preparation of both the surface to be tested and the PosiTector RTR H are necessary before performing the test.
To prepare surface: Use cleaning putty to remove dust, debris, or residual blast media from the measurement site by firmly pressing the putty onto surface to be tested using your fingers and remove
To prepare the PosiTector:
Clean anvils using included cleaning card. Swipe card through opening a few times while firmly pressing both probe buttons to remove dust
Zero probe and verify accuracy with included shim
Ensure correct grade of replica tape is displayed in upper left hand corner of LCD

Burnish

Testex Press-O-Film™ replica tape consists of a layer of compressible foam affixed to an incompressible polyester film of highly uniform thickness. When pressed against a surface, the foam forms an impression, or reverse replica, of the surface.
RTR H
- Select appropriate grade of replica tape based on target profile
- Pull a single adhesive-backed replica tape free of its release paper and apply to blasted surface
- 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 for 30-60 seconds to fully compress all parts of the film. In general, too much compression is safer than too little.
- When complete, remove replica tape from surface
RTR3D
- For best results when acquiring 2D/3D parameters and images from the PosiTector RTR 3D, it is recommended to use the supplied burnishing ball instead of the stainless-steel burnishing tool.
- Adhere the replica tape to the surface to be burnished.
- Holding the ball in two hands using your index fingers and thumbs, place the ball on the replica tape.
- Gently roll the ball over the tape while viewing the burnished tape through the clear ball. Adjust the force applied to the ball until a replica of the surface begins to appear on the tape.
- Continue to roll the ball until the tape is completely burnished (at least 30 seconds). measure with PosiTector RTR3

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 Testex Press-O-Film‚ 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.
Once positioned, firmly press both probe buttons simultaneously and hold until the PosiTector beeps and the measurement is displayed.
The gage automatically subtracts the thickness of the polyester substrate from all measurements. (RTR H)
RTR3D - After placing the compressed tape (replica) into the PosiTector RTR 3D a light-intensity versus thickness algorithm is used to produce a three dimensional (3D) image of the replicated surface.
RTR H - Placing the compressed tape (replica) into the PosiTector RTR H gives a measure of the average maximum peak-to-valley height of the surface roughness profile.
