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. Additionally, the PosiTector accepts a number of probe types including magnetic and eddy current coating thickness, surface profile, environmental and ultrasonic wall thickness probes.
Press-O-Film Replica Tape Press-O-Film provides a simple way to obtain an impression of a surface for analysis. It consists of a layer of crushable plastic micro foam affixed to a 50.8 µm (2 mil) incompressible polyester film. When compressed against a roughened surface, the foam collapses and acquires an accurate impression, or reverse replica, of the surface. It is available in a number of grades to accommodate measurements in different profile ranges.
Apply replica tape to blasted surface. Press the adhesive-backed ends of the paper to hold it firmly in place during the burnishing process. Firmly compress replica film using the rounded end of the included stainless steel burnishing tool. Apply sufficient pressure in a circular and x-y rubbing motion to produce a replica with a uniform pebble grain appearance. It normally takes 30 to 60 seconds to fully compress all parts of the film on most surfaces.
Measure Insert the burnished replica tape into the measurement opening. Ensure the tape is properly positioned so that the burnished region is centered within the opening in the probe with the adhesive (sticky) side down. To position the tape, move the tape to the back of the probe and align the two dots (printed on replica tape) with arrows on both sides of the measurement opening.
Calibration & Verification of Accuracy Calibration Gage calibration is typically performed by the manufacturer or accredited lab. All probes include a Certificate of Calibration. Verification of Accuracy Gage accuracy is verified using the included check shim. Ensure that the probe has been cleaned with the included cleaning card and that the probe has been zeroed (pg. 10). Place the check shim into the measurement opening.
Menu Operation Gage 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 RTR Advanced model: Some buttons have a tick box to their right to indicate current status. An empty box indicates that feature is not active.
Cal Settings Menu Zero The probe should be zeroed regularly to ensure best accuracy. While the user will be required to zero the probe every time the Gage is powered-up. The Zero menu item allows the procedure to be performed at more regular intervals. It is particularly useful during long measurement sessions. Clean the probe with the included cleaning card (pg. 7) before performing a probe zero. 1. Select Zero from the Cal Settings menu 2.
Linearize This is the default measurement mode. Linearize mode is ON when this box is ticked and the "HL" appears on the display. An undesirable characteristic of replica tape is that measurements made with analog spring micrometers are most accurate near the middle of each grade's range and least accurate at the outer ends of each grade's range.
During measurement, if the linearized measurement falls outside of the selected tape grade's range, the Gage will suggest a more suitable tape grade to perform the measurement. 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, batch names and screen captures are erased.
Flip Display This option causes the display to read upside down allowing for alternate positioning techniques. 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.
Memory Management The PosiTector RTR 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.
Delete Removes a batch completely from memory. The name is deleted and all measurements are erased. View Scroll using the Up or Down buttons through information, statistical summary, and a list of each reading in the currently opened batch. Press to exit. Annotate Create meaningful batch names and enter notes directly on the Gage using a familiar onscreen QWERTY keyboard. Use the Gage’s navigation and (-)(+) buttons to enter annotations. Annotations can be synchronized with PosiSoft.
Display (appears only if a batch is currently open) The following user selectable display options are available: Chart: A real-time chart of batch readings x-y Chart Image: Batch image Notes: Instructions, descriptions or notes (see Annotate, pg.16) None: Default screen shows statistics When a batch is open, press Up to scroll through the above Shortcut: display options. NOTE: PosiSoft.net (pg. 20) and PosiSoft Mobile (pg. 21) are used to insert an Image and Notes into a batch.
Summaries (Advanced models only) Displays a summary of all stored batches including the name, probe type, number of readings and type. In the following example, Batch 3 (B3) indicates an “F” 6000 coating thickness probe was used to record a total of “6” readings in “PA2” mode. Screen Capture Press both (-)(+) buttons at any time to capture and save an image copy of the current display.
