Floor Materials and Footwear - Resistance Measurement
in Combination with a Person (ANSI/ESD STM97.1)
Figure 11. Using the Handheld Electrode
Measure Resistance Point-to-Point (Rtt) on the
Surface
1. Do not clean the surface.
2. Remove from the surface only those items that
might interfere with the test. ESD sensitive devices
shall also be removed.
3. Connect both test leads to both 5-pound electrodes,
and place the electrodes on the most commonly
used area of the surface. Use the 10" electrode
spacer to space them 10" apart from each other.
The electrodes should also be 2" away from any
edge and 3" away from any grounded point. If the
most used area is not obvious, use two points near
the center of the surface.
4. Push the red pushbutton to perform a measurement.
Should the 15-second electrification period appear,
it may be bypassed by pushing the red pushbutton
a second time.

5. Push the right black pushbutton to save the
measurement if desired.
6. Perform additional measurements by placing the
electrode on the most commonly used or worn area.
