ESD protected area products should be tested:
1. Prior to installation to qualify product for listing in user's ESD control plan.
2. During initial installation.
3. For periodic checks of installed products as part of IEC 61340-5-1 Edition 1 2007-08 clause 5.2.3 Compliance verification plan.
As ESD floor and working surface matting get dirty which can increase their resistance. It is therefore recommended to check ESD surfaces regularly using a resistance checker.
The Vermason Analogue Surface Resistance Test Kit is a portable battery-powered instrument designed to measure resistance point-to-point (Rp-p) and surface to ground (Rg). The meter is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 1 x 105 ohms. Watch our video to see how to use the Vermason Analogue Surface Resistance Tester.
