Video: Measuring Walking Body Voltage (Test Method: ANSI/ESD STM97.2)
August 4, 2017
In this short video, we show you how to perform the ANSI/ESD-approved test, method STM97.2, to measure walking body voltage.

The static that’s generated when we walk is called walking body voltage. To measure that voltage, we use a charge monitor, something like the instrument in my hand.
Here’s a great example of what we’re talking about. In this clip, a person is stepping
across a conductive vinyl floor while wearing special static-control heel straps. This is what a heel strap looks like for those of you who’ve never seen one. Notice they are generating less than 25 volts of static. That’s very good.
Now look what happens when the same person walks on the same floor wearing a pair of ordinary sneakers. 3,000 volts. That’s enough to destroy, damage, or corrupt equipment. This is why you need to do two tests: a Resistance test and a Walking Body Voltage test. And this is why we always tell our clients that they should never specify a floor just because a supplier tells them how conductive that floor is.
In order to serve your needs, the floor must also be low static generating.
