TECHNICAL BULLETIN TB-3076 Digital Surface Resistance Meter Kit Installation, Operation and Maintenance Made in the United States of America The Surface Resistance Meter is referenced and designed to be used to make measurements in accordance with the test procedures in: Compliance Verification - ESD TR53 - Resistance Measurements Worksurfaces - ANSI/ESD S4.1 Worksurfaces Floors - ANSI/ESD S7.1- Resistive Characterization of Materials Floor Materials Foot Grounders - ESD SP9.2 - Foot Grounders Resistive Characterization Garments - ANSI/ESD STM2.1 Garments Seating - ANSI/ESD STM12.1- Seating - Resistive Measurement Floor/Footwear - ANSI/ESD STM97.1 - Floor Materials and Footwear- Resistance Measurement in Combination with a Person A Compliance Verification Plan shall be established to ensure the Organizations 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 Figure 1. Desco Digital Surface Resistance Meter Kit verifications shall occur. The Compliance Verification Plan shall document the test methods and equipment Description used for process monitoring and measurements. If the test methods used by the Organization differ from any The Desco 19290 Digital Surface Resistance Meter of the standards referenced in this document, then Kit is an instrument designed to measure resistance there must be a tailoring statement that is documented point-to-point (Rtt) or surface to ground (Rtg). as part of the ESD Control Program Plan. Compliance Its test functions include: verification records shall be established and maintained 3 12 Resistance range of <1 x 10 ohms to >1 x 10 to provide evidence of conformity to the technical ohms requirements. The test equipment selected shall be Under load voltages of 10 and 100 volts 5% capable of making the measurements defined in the Electrification period of approximately 15 seconds Compliance Verification Plan. (ANSI/ESD S20.20 section 7.3) The Digital Surface Resistance Meter also measures ambient temperature and relative humidity. Up to 100 measurements may be stored and recalled from the meter s internal memory. This includes the resistance value, temperature, relative humidity and test voltage at the time of the measurement.
