  • Page 2 It is also reusable, and a single PosiPatch can be used for multiple tests. The PosiTector SST can be used as a conventional conductivity meter making it ideal for testing abrasive materials in accordance with ISO 11127-6 and ASTM D4940-15. See Bresle Mode (pg.

  • Page 3: Quick Start

    Quick Start Press the button to power up the Gage. To conserve battery life, the gage will automatically go to sleep after 5 minutes of inactivity (15 minutes while in Bresle Mode, pg. 10). While in Sleep Mode, the gage powers up significantly faster— convenient when moving between parts or locations.

    SST test cell, test cup, syringe and PosiPatch (if used in test). All test materials should be handled in a manner that minimizes the potential for contamination. The PosiTector SST operator may choose to wear nitrile or other non-contaminating gloves when performing the test.
  • Page 5 Fill the syringe completely with DI water from the cup (slightly more than 3 ml). c) Completely fill the PosiTector SST probe’s test cell with water from the syringe (approximately 1 ml). d) Wait until the measurement stabilizes (up to 5 seconds), then...
  • Page 6 PosiPatch. On vertical surfaces, insert the dispensing tip only as far as is needed to see the tip inside the PosiPatch. Option B: Bresle Method DeFelsko Patch (or equivalent) a) Remove the backing and foam center from the patch, taking care not to touch the interior surface.
  • Page 7 ISO 8502-6 recommends this process be completed at least four times and that the test time be agreed between interested parties. DeFelsko recommends a test time of two minutes or longer. c) After the desired amount of time has elapsed, withdraw the water from the patch.

  • Page 9: Calibration And Verification

    Calibration and Verification Two steps ensure best accuracy… 1. Calibration: typically performed by the manufacturer. All probes include a Certificate of Calibration. 2. Verification of Accuracy: typically performed by the user by measuring known reference standards such as the supplied conductivity standard.

  • Page 10: Setup Menu

    Setup Menu Units Allows the operator to change the displayed units for both Temperature (°C or °F) and Surface Density (mg/m or µg/cm Reset Reset (menu Reset) restores factory settings and returns the Gage to a known condition. The following occurs: - All batches, stored measurements, batch names and screen captures are erased.
  • Page 11 Cal Adjust (Calibration Adjustment) The PosiTector SST can be adjusted to a known conductivity standard. Use the buttons to decrease/increase the displayed value to match the known conductivity of the standard. NOTE: In typical use, a calibration adjustment should not be required.

  • Page 12: Memory Management

    No damage will occur if the battery type used in the Gage does not match the selected battery type. Memory Management The PosiTector SST has internal memory storage for recording measurement data. Stored measurements can be reviewed on- screen or accessed via computers, tablets and smart phones. All stored measurements are date and time-stamped.

  • Page 13: Accessing Stored Measurement Data

    Accessing Stored Measurement Data DeFelsko offers the following free solutions for viewing, analyzing and reporting data: PosiSoft USB Drive - Connect the Gage to a PC/Mac using the supplied USB-C cable. View and print readings and graphs using universal PC/Mac web browsers or file explorers. No software or internet connection required.
  • Page 14 NOTE: When connected, power is supplied through the USB-C cable. The batteries are not used and the body will not automatically power down. Keyboard When enabled and connected to a computer, the PosiTector will (Advanced models only) be recognized as a Keyboard. Readings are sent to the computer as they are taken, emulating keystrokes, followed by a carriage return.
  • Page 15 (Advanced models only) Allows communication with a smart device running the PosiTector App (pg. 12) via auto-pairing Bluetooth Smart (BLE) wireless technology. Sync Batches Select batches to flag them for synchronization to the PosiTector App. Sync Batches is useful when connecting a new device to a gage with pre-existing batches, since only batches created while Bluetooth Smart is enabled are automatically selected.

  • Page 16: Returning For Service

    Returning for Service Before returning the instrument for service… 1. Install new or newly recharged batteries in the proper alignment as shown within battery compartment. 2. Examine the probe for damage. Use the supplied cleaning tool to clear dirt or debris from the test cell. 3.
