*This cannot be verified with standard DC test
equipment. The continuous monitor is an impedance
sensing device, and the limits are determined by the
magnitude and angle of the impedance.
**The worksurface mat must have a conductive
layer such as Dual Layer Rubber or Dissipative
3-Layer Vinyl with conductive buried layers. Desco
workstation monitors are not recommended for use with
homogeneous matting.
ANSI/ESD S20.20 requires the use of a surface
resistance meter for periodic verification of a
worksurface's resistance-to-ground (Rtg). Constant
monitors may not be used as a substitute for this
requirement.
