Description
The Desco
portable battery powered checker fitted with built-in
parallel electrodes that allow for tests of material
surface resistance. This meter is designed for
quick checks of surface resistance for ESD control
applications in electronics manufacturing or handling
environment. The Surface Resistance Checker is
equipped with an automatic test voltage selector. The test
voltage will switch from 10V to 100V should the measured
resistance exceed 1 x 10E5 ohms. Two banana jacks
and an electrode toggle switch allow for the connection
of two external 5 pound electrodes that measure
surface resistance point to point (RTT) or resistance to
equipment ground (RTG).

ESD protected area products should be tested:
A. Prior to installation to qualify for listing in user’s ESD
B. During initial installation
C. For periodic checks of installed products as part of
Compliance Verification Plan
“A Compliance Verification Plan shall be established
to ensure the Organization’s fulfillment of the technical
requirements of the ESD Control Program Plan. Process
monitoring (measurements) shall be conducted in
accordance with a Compliance Verification Plan that
identifies the technical requirements to be verified, the
measurement limits and the frequency at which those
verifications shall occur. The Compliance Verification Plan
shall document the test methods and equipment used
for process monitoring and measurements. If the test
methods used by the Organization differ from any of the
standards referenced in this document, then there must
be a tailoring statement that is documented as part of the
ESD Control Program Plan. Compliance verification records
shall be established and maintained to provide evidence of
conformity to the technical requirements.
The test equipment selected shall be capable of making the
measurements defined in the Compliance Verification Plan.”
