Digital Surface Resistance Meter Kit
Installation, Operation and Maintenance
Description
The Desco 19787 Digital Surface Resistance Meter Kit is
an instrument designed to measure resistance point-to-point
(Rtt) or surface to ground (Rtg) in accordance with ESD
Association Standard ANSI/ESD S4.1.
Its test funcitions include:
• Resistance measurement accuracy of ±10%
(±20% for resistance values 1 x 10
11
and greater)
• Resistance range of <1 x 10
3
ohms to >1 x 10
12
ohms
• Under load voltages of 10 and 100 volts ±5%
• Electrification period of approximately 15 seconds
The Digital Surface Resistance Meter also measures ambient
temperature and relative humidity.
The Digital Surface Resistance Meter Kit and its accessories
are available in the following item numbers:

“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.”
