  2. About the Conductivity Test Apparatus The Conductivity Test Apparatus (CTA) is a simple device that works in conjunction with an ohm meter. CTA Benefits: • Constant calibrated weight applied to test strip / slide • Four calibrated probes to accurately measure resistivity (per ASTM D2739) • Easy set up to Ohm meter for quick readings with consistent precision • Gold plated Copper electrodes! Weight: 5.7 lbs. (2590 grams) Length: 9” (23 cm) . Width: 4“ (10 cm) . Height: 3.75” (9.5 cm) .

  3. Materials Needed • Conductivity Test Apparatus (CTA) • Calibrated weight (included) • Slide with conductive paste/ink/adhesive • Ohm meter (microcontroller) (not included) • Set up on a level surface near an outlet

  4. Set Up • Set up on a level surface near an outlet • This is to connect the Ohm meter • Correctly hook up the four electrodes to the CTA and Ohm meter as seen in the pictures 1 and 2 to the right. Picture 1: CTA electrode hook up example. Picture 2: Ohm meter electrode hook up example.

  5. Set Up Continued • Take testing slide (see picture 3) and place it on top of the four electrodes on top of the CTA (see picture 4). • Jig is available for making test strip (please inquire) Picture 3: Example of testing slide with conductive silver paste on one side. Picture 4: Example of testing slide with conductive silver paste on one side.

  6. Set Up Continued • Pick up weight seen in picture 5. • Place weight directly on top of testing slide, seen in picture 6. Picture 5: Weight Picture 6: Weight on top of testing slide.

  7. Set Up Continued • Read and record the resistivity on the Ohm meter. • You can use this value to calculate the conductivity of your conductive test slide. Resistance (Ω) Thickness (mm)  Width (mm) . Distance Between Measuring Points (mm) Volume Resistivity =
