  • Page 1 PosiTector 200 INSTRUCTION MANUAL v. 2.0 Ultrasonic Coating Thickness Gage Standard Advanced Simple. Durable. Accurate.

  • Page 2: Power-Up / Power-Down

    Thickness Gage that uses a non-destructive ultrasonic principle to measure coating thickness on a wide variety of substrates. The PosiTector 200 probe emits a high frequency sound pulse that travels into the coating via a coupling gel and reflects from ANY surface that is different in density.

  • Page 3: Operation Overview

    All probes or gages are shipped with a Certificate of Calibration. For organizations with re-certification requirements, gages may be returned at regular intervals for calibration. DeFelsko recommends that customers establish gage calibration intervals based upon their own experience and work environment.

  • Page 5: How To Measure

    How to Measure How to Measure 1. Apply couplant to the surface of your part. 2. After power-up, place the probe FLAT on the surface and press down. 3. Lift the probe when you hear a double BEEP or see the green indi- cator light blink.
  • Page 6 Important: When measuring, the Gage finds the most distinct interface within the two Gate settings. If the coating thickness is outside this range, incorrect or dashed readings may occur. The PosiTector 200 interprets the largest “echo” or echoes within the gates as the coating/substrate echo.
  • Page 7 To make adjustments: 1. Measure the coated part. 2. Select the Set Gates menu option. 3. Gate A can be changed first. Adjust the value down (-) or up (+). Press to accept the value and to move to Gate B. 4.
  • Page 8 Adjust Thickness Option Adjust Thickness Option Adj Thickness Select a reference standard of material as close as possible in composition to the intended application. For best results, the thickness of the reference stan- dard should be equal to or slightly greater than the thickness of the coating to be measured.

  • Page 9: Memory Mode Memory

    Memory Mode Memory Mode Memory PosiTector record 10,000 measurements in up to 1000 groups (batches) for on-screen statistical purposes, for printing to an optional IR printer, or for downloading to a personal computer using optional PosiSoft software and USB cable. New Batch -closes any currently opened batch and creates a new batch name using the next higher number.
  • Page 10 Close -stops the recording process, closes the current batch, and removes the statistics from the display. Delete -removes a batch completely from memory. The name is deleted and all measurements are erased. View -lists all readings on the display from the current or most recently used batch.

  • Page 15: Application Notes

    The PosiTector 200 is factory calibrated. But in order for it to take accurate thickness measurements of a particular material it might be necessary to adjust the gage for that material. To determine if an adjustment is necessary for your application, measure a sample of known thickness of the coating material to be measured.
  • Page 16 limits of the gage and assumes the largest “echo” is coating/substrate echo (single coating applications only). Adjustable measurement Gates have been provided for the user to force the instrument to ignore echoes from unwanted boundaries within the sample. Several examples below help to illustrate the use of Gates for specific applications.
