  • Page 4: Introduction

    Introduction Introduction The PosiTector 200 is a hand-held Coating Thickness Gage that uses a non-destructive ultrasonic principle to measure coating thickness on a wide variety of substrates. It consists of a body (Standard or Advanced) and a probe (see Probes pg. 7).

  • Page 5: Certification

    Protective Cap PosiTector 200 gages ship with a protective rubber 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.

  • Page 7: Probes

    Probes Probes PosiTector 200 probes are available for measuring a wide variety of coating thickness applications. B probe - 13 to 1000 microns (0.5 to 40 mils) Ideal for polymer coatings on wood, plastic, composites, etc. C probe - 50 to 3800 microns (2 to 150 mils) Ideal for thicker coatings on concrete, fiberglass, etc.

    Ultrasonic Thickness Theory of Operation Theory of Operation 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. Coating thickness readings...

  • Page 9: Calibration, Verification And Adjustment

    Calibration, Verification and Adjustment Calibration, Verification and Adjustment Three steps ensure best accuracy… 1.Calibration - typically done by the manufacturer. All probes include a Certificate of Calibration. 2.Verification of Accuracy - typically done by the user on known reference standards such as plastic shims or coated thickness standards.

  • Page 10: Menu Operation

    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 200 Advanced model: Memory Some buttons have a tick box to their Cal Settings right to indicate current status.

  • Page 11: Cal Settings Menu

    Cal Settings Menu Cal Settings Menu Zero PosiTector 200 probes must be periodically zeroed using the ZERO menu option to compensate for both extreme temperature and probe wear effects. Before using, allow the probe to reach ambient temperature. If measurements will be made in extreme hot or cold temperatures, it is recommended to ZERO the probe in the working environment.

  • Page 12: Thickness

    25µm (1 mil) 250µm (10 mils) Thickness The PosiTector 200 measures most polymer coatings accurately out-of-box with no adjustment required. To determine if an adjustment is necessary, select a coating sample of known thickness as close as possible in composition to the intended application.

  • Page 13: Setup Menu

    Setup Menu 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. - All calibration and range adjustments are cleared and returned to the Gage’s factory settings.

  • Page 14: Gage Info

    The PosiTector 200 chooses the highest peak (single layer) or peaks (multi-layer) within the Set Range. For example, if the number of layers is set to 3, the three highest peaks would be identified with small red triangles.
  • Page 15 Use the navigation Up (move left) and Down (move right) buttons to highlight icons on the graphic display. Zoom - Visually magnifies the waveform of the displayed peaks for more visibility. Pressing the (+) or (-) button repeatedly will increase/decrease the zoom. Set Range - Press the (-) or (+) buttons to adjust the Gage’s Lo or Hi measuring range (See pg.

  • Page 17 (Gage must be powered ON). The battery state indicator icon is calibrated for the selected battery type. No damage will occur if the wrong battery type is selected. DeFelsko recommends eneloop (NiMH) rechargeable batteries (pg. 36). Units Converts the display from inch to metric or vice versa. Stored measurements in memory are not converted.

  • Page 18: Memory Management

    Memory Management Memory Management The PosiTector 200 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: Create a new batch...

  • Page 19: Advanced Models Menu

    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.

  • Page 20: Annotate

    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.
  • Page 21 NOTE: PosiSoft.net (pg. 24) and the PosiSoft App (pg. 25) 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.

    Probe Couplant Coating Substrate Measurement of dense (hard) coatings. A significant echo occurs at the probe/coating interface. The relative strength of this echo compared to the coating/substrate echo requires that Lo Value be increased. Measurement of total thickness in multi-layer coating applications.

  • Page 32: Gage Readings Are Higher Than Expected

    Gage readings are much higher than expected Gage may be measuring both the coating and substrate. Lower the value of Hi Range (See pg. 11). Gage does not yield accurate or consistent results See the Set Range (pg. 11) and Thickness Adjustment (pg. 12) sections to ensure the Gage has been optimized for your application.
