TECHNICAL BULLETIN TB-7588 Digital Surface Resistance Meter Kit Installation, Operation and Maintenance Made in the United States of America The Surface Resistance Meter Kit (or its Meter) is referenced and designed to be used to make measurements in accordance with the test procedures in: Working surfaces, storage racks, trolleys and seating - IEC 61340-2-3 Flooring - IEC 61340-4-1 Garments - ANSI/ESD STM2.1 Garments Person/footwear / flooring system - IEC 61340-4-5 A compliance verification plan shall be established to ensure the Organizations fulfilment of the technical requirements of the 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 must document the test methods and equipment used for process monitoring and measurements. If the organization Figure 1. Vermason Digital Surface Resistance Meter uses test methods that differ from the standards referenced Kit in this standard, the organization must be able to show that Description the results achieved correlate with the referenced standards. Compliance verification records shall be established and The Vermason 222642 Digital Surface Resistance Meter maintained to provide evidence of conformity to the technical Kit is an instrument designed to measure resistance requirements. point-to-point (Rp-p) or surface to ground (Rg) in accordance The test equipment selected shall be capable of making the with EN 61340-5-1 Electrostatics and its test method IEC measurements defined in the compliance verification plan. 61340-2-3. (IEC 61340-5-1 Edition 1 2007-08 clause 5.2.3 Compliance Its test funcitions include: verification plan) Resistance measurement accuracy of 10% 11 (20% for resistance values 1 x 10 ohms and greater) Reference Literature 3 12 Resistance range of <1 x 10 ohms to >1 x 10 ohms In addition to those noted above: Under load voltages of 10 and 100 volts 5% EN 61340-5-1 Electrostatics and PD CLC/TR 61340-5-2 User Electrification period of approximately 15 seconds Guide Electrostatics The Digital Surface Resistance Meter also measures ambient These documents can be obtained from from British temperature and relative humidity.
