SR-496 Surface Resistance Meter
Instruction Manual
The surface resistance can be measured by attaching two parallel electrodes of the instrument to the surface
of the measured object. Thus you can determine whether the measured object is a conductor, anti-static
material, or an insulator. The instrument is particularly suitable for a variety of anti-static areas.

The signal is weak when measure surface resistance of 10
11
Ω or more, in order to ensure stable and
reliable measurement, it is necessary to make environment where electromagnetic interference is small.
During the measurement process, make sure that no person walks within 3 meters.
