PosiTector® SmartLink
with PosiTector SPG probes
Instruction Manual v1.0 - AndroidTM

Introduction

PosiTector SPG probes measure the peak-to-valley height of the surface profile of abrasive blast cleaned surfaces. 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 SPG, compatible probes include the PosiTector RTR-H (replica tape reader), 6000 (coating thickness) and DPM (environmental conditions).

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.

Quick Start

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).

Wirelessly Connect the PosiTector probe to the smart device using the PosiTector App.

Measure

1. Remove the protective rubber cap from probe.

2. Place the included glass zero plate onto a stable, flat surface. Take a reading on the plate. If the average of several readings is not within tolerance of the probe, zero the probe.

3. 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 until a reading is displayed.

Lift the probe from the surface between readings.

PosiTector App

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.


Prior to uninstalling the PosiTector App or performing a Reset it is recommended that you share the batch data via email report. This ensures that the data is saved for future reference.

Wirelessly Connecting the PosiTector App to a PosiTector SPG probe

1. Power-up the PosiTector SmartLink and connected SPG probe by pressing the LED button. The button will blink blue.

2. Select the PosiTector SmartLink App icon on your smart device.

PosiTector SPG Probes

PosiTector SPG probes measure the peak-to-valley height of the surface profile of abrasive blast cleaned surfaces.

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.

More probe information is available at www.defelsko.com/spg

Protective Cap
PosiTector SPG probes are shipped with a protective rubber cap. Remove this cap prior to use. Replace it when the instrument is not in use to protect the probe.

Factory Calibration
Every PosiTector SPG probe is factory calibrated and includes a Certificate of Calibration. This factory calibration information is permanently stored within the probe and cannot be overwritten by the user. The icon indicates factory calibration is in use.

Calibration Adjustment
The PosiTector SPG has only one adjustment point at zero. The Zero adjustment made by the user is stored within the PosiTector SmartLink.

Certification
PosiTector SPG probes include a Certificate of Calibration showing traceability to a National Metrology Institution. 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.

Calibration, Verification and Adjustment

The PosiTector SPG probes measure the peak-to-valley height of the surface profile of abrasive blast cleaned surfaces. Three steps ensure best accuracy...

1. Calibration - typically done by the manufacturer. All probes include a Certificate of Calibration

2. Verification - typically done by the user on known reference standards such as included metal shim

3. Adjustment - zero calibration adjustment on smooth flat surface (included glass plate)

Calibration
Calibration is the high-level, controlled and documented process of measuring traceable calibration standards over the full operating range of the probe, and verifying that the results are within the stated accuracy of the probe. Calibrations are performed by the manufacturer, their authorized agent, or by an accredited calibration laboratory in a controlled environment using a documented process.

PosiTector SPG probes are shipped 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
Verification is an accuracy check performed by the user using known reference standards. A successful verification requires the Gage to read within the combined accuracy of the probe and the reference standards.

Instrument accuracy is verified using the included metal shim and glass zero plate.

Place the plate onto a stable, flat surface. Take several readings. If the average is not within tolerance of the probe, zero the probe.

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 readings should be within the combined tolerances of both the shim and the gage.

Verify accuracy 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 probe should be returned to the manufacturer for repair or calibration.

Zero Calibration Adjustment
The PosiTector SPG has only one adjustment point at zero.

Zeroing the probe on the glass plate is the preferred zero adjustment method:

1. Select Zero 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 reading the gage will calculate a Zero which represents the average of all the Zero readings taken.

The icon will display.


If a glass plate or suitable smooth, hard surface is not available, factory zero calibration can be used. Factory calibration can be restored by performing a LED Button Reset.

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.
