RESISTANCE MEASUREMENTS:

Included with each Model 272A is a Model 96121-1 Surface-
to-Ground Measuring Adapter. This adapter used with the
probe and Model 272A meets requirements of the following
standards for measurement of resistance to ground of
flooring and work surface materials:

ASTM F-150
Standard Test Method for ELECTRICAL RESISTANCE OF
CONDUCTIVE RESILIENT FLOORING

ESD ASSOCIATION STANDARD NO. 4.1
Worksurfaces - Resistive characterization

ESD ASSOCIATION STANDARD NO. 7.1
Floor Materials - Resistive characterization of materials

NOTE: The adapter serves as a protective cap for the probe during storage and must be
removed to expose the concentric ring electrodes for resistivity measurements.

ASTM standards are available from:

Monroe Electronics, Inc. does not supply copies of standards.

To make a measurement of resistance from a surface to a ground point, connect the jack
labeled “OHMS” to the ground point, set the electrode on the surface and switch to the “OHMS”
mode (see Figure 2).

Surface-to-surface measurements, also directed in these standards, require the use of a second
electrode (Monroe Electronics Model 96083) as shown in Figure 2. Model 96083 electrodes are
included in Models 96085-1 and 96085-2 electrode sets or they may be ordered separately.
