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.

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

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.

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.

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.

PosiTector Body

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

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

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.

NOTE:

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.
