Introduction
Introduction
The PosiTector Surface Profile Gage (SPG) is a hand-held
electronic Gage that measures the peak-to-valley height of the
surface profile of abrasive blast cleaned surfaces. It consists of a
body (Standard or Advanced) and probe.
PosiTector SPG Kit Contents
- PosiTector body (Standard or Advanced)
- PosiTector probe (SPG)
- Glass zero plate amd metal shim
- Protective rubber holster with belt clip
- Protective cap for probe
- Protective lens shield
- Wrist strap
- 3 AAA alkaline batteries
- Quick Guide instruction booklet
- Nylon carrying case with shoulder strap
- USB Cable
- Certificate of Calibration traceable to NIST
- PosiSoft.net account

1. Remove the protective plastic cap from probe.
2. Power-up Gage by pressing the center navigation button.
3. Place the glass zero plate onto a stable, flat surface. Take
several measurements. If the average of several readings is
greater than ± 5 µm (0.2 mil), Zero the Gage (see pg. 8).
4. Place the probe FLAT on the surface to be measured such that
the tip of the probe reaches into the bottom of a profile valley.
HOLD STEADY. The Gage will BEEP twice and display the
measurement.
5. Lift the probe from the surface between measurements.
Quick Start
Quick Start
The PosiTector SPG powers-up when the center navigation
button is pressed. To preserve battery life, it powers-down after
approximately 5 minutes of no activity. All settings are retained.

2
Protective Cap
PosiTector SPG models are shipped with a protective plastic
cap over the probe. Remove this cap prior to use. Replace it
when the Gage is not in use to protect the probe.
Wrist Strap
We recommend attaching and wearing the
supplied wrist strap. 1
2
Plastic Lens Shield
The LCD 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.
Certification
All 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. Written calibration
procedures are available from DeFelsko Corporation at no
charge.

To disconnect a probe from a body, power-down the
Gage and slide the plastic probe connector horizontally
(in the direction of the arrow) away from the body.
Reverse these steps to attach a new probe.
When powered-up, the PosiTector automatically
determines which probe is attached and does a
self-check.
Probes
Probes
Additionally, the PosiTector accepts a number of probe types
including magnetic, eddy current and ultrasonic coating thickness,
surface profile, environmental and ultrasonic wall thickness
probes. Perform the latest software Updates (pg. 27) to ensure
probe compatibility with your Gage. For the latest information on
probe interchangeability see www.defelsko.com/probes
The supplied probe tip has a 60° angle to comply with most test
standards including ASTM D 4417 B. An optional 30° angle tip
with replacement tool is available for special applications or to
comply with Australian Standard AS 3894.5.
A replacement tool is included with the purchase of either the 60°
or 30° angle tips. Insert the two legs of the replacement tool into
the probe tip and turn counter clockwise to remove the tip. Insert
the new tip and tighten clockwise. Do not over tighten. Since the
factory zero setting may not always be precise after a probe tip
exchange, the gage should be checked on the included glass
plate and zeroed if necessary.

Why is Measurement Important?
Steel is often abrasive blast cleaned or otherwise roughened prior
to painting. The peak-to-valley height of the resultant surface
profile is an important factor in the performance of applied
protective coatings.
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.
How to Measure
How to Measure
1. Remove the protective rubber cap from probe.
2. Power-up Gage by pressing the center navigation
button.
3. Place the probe FLAT on the surface and press down.
4. Lift the probe when you hear a double BEEP.
6. When completely finished, return the Gage to the protective
pouch. There is no need to disconnect the probe from the
PosiTector during storage.

Calibration
Instrument calibration is typically done by the manufacturer or
qualified lab. All probes include a Certificate of Calibration showing
traceability to a national standard. For organizations with
re-certification requirements, the PosiTector SPG may be
returned at regular intervals for calibration.
DeFelsko recommends that our customers establish Gage
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.
Written Calibration Procedures are available online at no charge.
Verification of Accuracy
Instrument accuracy is verified using the included metal shim and
glass zero plate.
Place the plate onto a stable, flat surface. Take several
measurements. If the average is greater than ±5 µm (0.2 mil), Zero
the Gage (pg. 8).
Next, place the metal shim over the glass plate and measure
ensuring the probe needle touches the glass plate in the area
between the shim’s “legs”. The average of several measurements
should be within the combined tolerances of both the shim and the
gage (±10%). For example, measuring a 75 µm (3 mil) shim should
result in values between 67.5 µm (2.7 mils) and 82.5 µm (3.3 mils).
If not, see Returning for Service (pg. 31).
To guard against measuring with an improperly adjusted Gage,
verify the Gage at the beginning and the end of each work shift.
During the work shift, if the Gage is dropped or suspected of giving
erroneous readings, its accuracy should be re-verified.
In the event of physical damage, wear, high usage, or after an
established calibration interval, the gage should be returned to the
manufacturer for repair or calibration.

Zero Menu
Zero Menu
The PosiTector SPG has only one adjustment point at zero. The
zero point can be set using one of two methods. Both methods are
found under the Zero menu option.
-The factory zero setting is restored during a RESET
(below)
-The factory zero setting may not always be precise,
particularly after a probe tip exchange. For best accuracy,
the gage should be zeroed on the included glass plate.
1.Select from the menu.
2.Press the (+) button to select the number of readings to be
used to obtain an average, typically 3.
3.Repeatedly measure the glass plate. After the last
measurement the gage will calculate a Zero which represents the
average of all the Zero readings taken.
Zero
Glass Plate Zero
Setting the Gage to zero on the glass plate is the preferred zero
adjustment method:
Factory Zero
If a glass plate or suitable smooth, hard surface is not available,
the factory zero setting can be restored:
1. Select from the menu.
2. Press the down button to select “Reset” and press the center
navigation button . The factory calibration icon will appear
on the LCD.

Reset
Reset (soft reset) restores factory settings and returns the Gage to
a known condition. The following occurs:
- All batches, stored measurements, images, and batch names
are erased.
- The zero adjustment is returned to the factory setting. Since
this may not always be a precise zero, the gage should be
checked on the glass plate (pg. 8)
- Menu settings are returned to the following:
Memory = OFF
Statistics Mode = OFF
Hi Lo Alarm = OFF
Bluetooth = OFF
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 Gage to a known, “out-of-the-box”
condition. It performs the same function as a menu Reset with
addition of:

Creates a new sub-batch within the currently opened batch.
The PosiTector SPG measures the depth of a single valley in
relation to the height of the surrounding peaks using a pointed,
cone-shaped probe.
A single depth measurement generally does not adequately
characterize the surface profile of an abrasive blast cleaned
surface. Repeated gage readings often differ due to surface
irregularities even at points close together.

calibration setting (i.e. Cal 2) associated with this batch is also
opened.
A solid triangle is displayed to the right of the batch
name when sub-batches are present. Press to view sub-
batches. This also applies to the Delete, View and Print options.
NOTE:
Close
Stops the recording process, closes the current batch, and
removes batch information from the display.
Therefore most organizations and contract specifications require
multiple measurements be taken and analyzed to produce a final
result that better characterizes the surface.
The Smart Batch menu option sets-up the PosiTector SPG to
comply with the statistical approaches defined in various standards
and test methods published by organizations such as ASTM,
SSPC, ISO, IMO, US Navy, SANS and AS.
