Instruction Manual v. 1.0

The PosiTest AT Verifier kit is ideal for checking the accuracy and operation of
adhesion testers and is an important component in fulfilling both ISO and in-house
quality control requirements.

The kit is ready to use with all PosiTest pull-off adhesion testers. All setup
information has been preset by DeFelsko. No additional configuration is required
or recommended. If the Smart Sensor Indicator (SSI) settings are mistakenly
altered, see Reconfiguring the SSI Device (pg. 3).

Kit includes:

- Smart Sensor Indicator (SSI) Device

- Load Cell with steel 20mm Loading Fixture (dolly)

- Built-in rechargeable Lithium Ion Batteries

- Universal AC power adaptor/charger

- Instruction Manuals (2)

- Certificates of Calibration (2)

- Sample Certificate of Accuracy

- Measurement Uncertainty Worksheet

- Hard shell carrying case

1. Connect the PosiTest AT actuator to the load cell. Ensure the quick coupling is
locked in place over the dolly fixture. PosiTest AT-M (manual) models only: Close
the pressure relief valve (turn clockwise).

2. Press [Power] button to power-up the Smart Sensor Indicator (SSI).

3. Press and release the [TARE] button to ZERO the SSI.

4. Press and release the [PEAK] button to hold the maximum pressure value at
the completion of the test. PEAK will display on the SSI.

5. Power ON the PosiTest AT by pressing the green button.

-Ensure units are set to psi and dolly size to 20 mm.

-Important: PosiTest AT-A (automatic) models: Set the pull rate to 30 psi/sec

6. Press the button to ready the PosiTest AT.

7. Press the button again to start the test.

-PosiTest AT-A models will automatically begin building pressure*

-PosiTest AT-M models: slowly prime the pump until the priming pressure is
reached (100 psi)*. Return pump handle to its full upright position and maintain a
single slow, continuous pump at approximately 30 psi/sec until a verification point
has been reached.

*Make no comparisons between PosiTest adhesion tester and SSI measurements

until the priming pressure (100 psi) has been exceeded.

8. Stop the test when the verification point has been reached.

-PosiTest AT-A users press the red button. Reading will flash and
actuator will automatically release pressure.

-PosiTest AT-M users simply release the pump handle and open the pressure
relief valve (turn counter-clockwise).

9. Record values from PosiTest AT and Smart Sensor Indicator.

10. Prepare for next test verification point.

-Power-down the SSI by pressing the [Power] button.

-Ensure all pressure has been released within the adhesion tester by pushing
the PosiTest AT actuator handle completely down. The actuator should be relaxed
over the loading fixture.

Repeat steps 2-10 for each additional verification point. See included Sample
Certificate of Accuracy for recommended verification points.
