Resistivity Tester for Anti-Static Surfaces

The model S-385 surface resistance tester is used to check the resistivity of static dissipative and conductive surfaces, such as anti-static workstation mats.

How to check the surface resistance:

Checking the resistivity of anti-static mats is a simple process. Typically, the top side of the anti-static mat is dissipative and the bottom is conductive. The S-385 surface resistance meter can test the resistivity of both sides of the mat. The test measurement probes are built into the back panel of the surface resistance meter.

  1. Make sure the anti-static mat is wiped clean and dry. Lay the back of the resistance meter on the top surface of the anti-static mat.
  2. Press the red "Test" button.
  3. An LED on the measurement bar graph should illuminate within the "static dissipative" range indicating a good test result for the top mat surface.
  4. Now flip the mat over and repeat steps 1 through 3 on the bottom surface of the anti-static mat. An LED on the measurement bar graph should illuminate within the "conductive" range, indicating a good test result for the bottom side of the mat.
  5. The included ground cord lead can also be used to test resistivity from the surface of the mat to the earth ground in the same manor as outlined above.
  6. If any test produces a result in the "Insulative" range, there's a problem with either the anti-static mat or it's path to ground (the mat ground cord). Take corrective action.
