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.
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. 2 1 Plastic Lens Shield The LCD is covered with a thin plastic film for protection against fingerprints and other marks during shipment.

Probes 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. The supplied probe tip has a 60° angle to comply with most test standards including ASTM D 4417 B.
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.
Calibration & Verification of Accuracy 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.
Menu Operation Instrument functions are menu controlled. To access the Menu, power-up the Gage, then press the center navigation button. Below is a sample menu for a PosiTector SPG Advanced Model: Memory Statistics Zero Setup Connect Help Power Off Exit Some buttons have a tick box to their right to indicate current status. An empty box indicates that feature is not active.
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. Glass Plate Zero Setting the Gage to zero 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.
Setup Menu 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.
Flip Display This option causes the display to rotate 180°. Ideal for right-sideup viewing when the sensors are pointed away from the user. White on Black (Advanced models only) Inverts the LCD display to white on a black background to provide better readability in some surroundings. (Advanced models only) Backlight Selects display brightness (Sun, Normal or Night). All settings will dim slightly after a period of no activity to conserve battery life. Press the Down button to brighten the display.

Press (+) to clear statistics.
Memory Management The PosiTector SPG has internal memory storage for recording measurement data. Stored measurements can be reviewed on-screen or accessed via computers, tablets and smart phones. Measurements are date and time-stamped. Button functions with Memory ON: Scroll through display modes (Advanced only) Create a new batch (Advanced only) Delete last reading Restore brightness after dimming (Advanced only) Access the Menu Standard models store up to 250 readings in one batch.
Advanced models store 100,000 readings in up to 1,000 batches. The Memory Menu includes the following options... New Batch Closes any currently opened batch and creates a new batch name using the lowest available number. For example, if only Batch 1 and Batch 3 exist, then Batch 2 would be created and made the current batch. The icon appears and basic statistics are displayed. Each measurement will be displayed and stored into this new batch.
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. For instructions on how to use the Smart Batch™ feature, see www.defelsko.
Annotate (Advanced models only) Create meaningful batch names and enter notes directly on the Gage using a familiar onscreen QWERTY keyboard. Use the Gages navigation and (-)(+) buttons to enter annotations. Annotations can be synchronized with PosiSoft.netand are included in all PosiSoft reports (see Accessing Stored Measurement Data, pg. 18). NOTE: Annotations can also be created using PosiSoft.net (pg. 19) or PosiSoft Mobile (pg. 20).
Display (appears only if a batch is currently open) The following user selectable display options are available: Chart: A real-time chart of batch or sub-batch readings x-y Chart Image: Batch image Notes: Instructions, descriptions or notes (see Annotate, pg.15) None: Default screen shows statistics When a batch is open, press Up to scroll through the above Shortcut: display options. NOTE: PosiSoft.net (pg. 19) and PosiSoft Mobile (pg. 20) are used to insert an Image and Notes into a batch.
NOTES: Remove the last reading from the current open batch by pressing (-). Calibration adjustments cannot be made if any measurements were taken with that Cal setting and stored into a batch. Each batch can contain a maximum of 10,000 readings. Summaries (Advanced models only) Displays a summary of all stored batches including the name, probe type, number of readings and type.
Accessing Stored Measurement Data PosiSoft solutions for viewing, analyzing and reporting data: PosiSoft USB Drive - connect the PosiTector to a PC/Mac using the supplied USB cable to access and print stored readings, graphs, photos, notes and screen captures. No software or internet connection required. USB Drive must be selected (see pg. 21). PosiSoft.net - a free web-based application offering secure centralized storage of PosiTector readings.
