Introduction
Introduction
The PosiTector Re lica Ta e Reader (RTR) is a hand-held
electronic instrument that measures burnished Testex Press-O-
ilmTM replica tape to produce peak-to-valley surface profile height
measurements. It consists of a PosiTector body (Standard or
Advanced) and probe (R R-H or R R-P)
PosiTector R R-P models also measure peak density (Pd).
Advanced R R-P models generate 2D/3D images and SD
Surface Data iles.
A surface cleaned by abrasive blast is best described using two
measured parameters: eak height and eak 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
pg. 16.
Peak Density (R R P only)
Pd – the number of peaks per square millimeter or square inch.

Quick Start
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 good
practice to clean the probe regularly with the included cleaning
card. Cleaning is best performed when the Gage is powered down.
NOTE:
With the Gage powered down...
1. Clean the probe with the included cleaning card. (pg. 12)
2. Power-up Gage by pressing the center navigation button.
3. Zero the probe. (pg. 15)
4. Verify Gage accuracy. (pg. 13)
5. Measure the burnished replica tape. (pg. 10)

Protective 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.

PosiTector bodies accept all interchangeable probes including
surface profile (R R/SPG), coating thickness (6000/200),
environmental (DPM), Shore Hardness (SHD), soluble salt (SST),
and ultrasonic wall thickness (U G) probes.
Updates: Keep your PosiTector current with software updates
containing the latest features, functionality and probe compatibility
(see Updates pg. 34).
Power Source: 3 AAA alkaline, Lithium or optional Nickel-metal
hydride (NiMH) rechargeable batteries. or best battery indicator
results, ensure the appropriate Battery Type is selected in the
Setup > Battery Type menu (pg. 21).
The battery indicator displays a full bar with fresh alkaline
or fully charged batteries installed. As the batteries weaken, the
bar will be reduced. When the battery symbol is low
the Gage can still be used, but the batteries should be changed or
recharged at the earliest opportunity (pg. 36).

Additional PosiTector Probes:
The PosiTector body accepts a wide variety of probe types
including magnetic, eddy current and ultrasonic coating thickness,
surface profile, Shore hardness durometer, salt contamination and
ultrasonic wall thickness probes. See www.defelsko.com/probes

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 new probe.
It is not necessary to power-down the gage when
interchanging probes.

A smart new way to measure!
-wirelessly connect R R-H probes to your smart device
-turn your cell phone or tablet into a virtual PosiTector gage
-includes free PosiTector app
Certification
PosiTector RTR probes include a Certificate of Calibration.
or organizations with re-certification requirements, instruments
may be returned at regular intervals for calibration.
De elsko 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 profle 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.
or these reasons, surface profile should be measured prior to
coating application to ensure that it meets contract specifications.
