For periodic checks of installed products as part of ESD control plan compliance verification plan Features A Compliance Verification Plan shall be established to ensure the Organizations fulfillment of the technical E 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 B measurement limits and the frequency at which those A verifications shall occur. The Compliance Verification Plan shall document the test methods and equipment used for process monitoring and measurements. If the test C 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 D G conformity to the technical requirements. The test equipment selected shall be capable of making the measurements defined in the Compliance Verification Plan. F (ANSI/ESD S20.20-2007 section 7.3) Electrification Period Figure 2. Features of the Surface Resistance Meter The Surface Resistance Test Kit provides the proper electrification period of 15 seconds per ANSI/ESD S4.1, A. LED Displays: Surface resistance exponent is displayed after numerous readings and calculations are executed, via light emitting diodes illuminating 1/8 high number. then displays surface resistance mantissa measurement There are 12 LEDs displaying surface resistance exponent (Note: most analog type meters display measurements measurement. They are color coded for quick checks: instantaneously). Exponent Color When the Test Button is depressed, the liquid crystal <3, 3 Red display (LCD) will indicate: 4, 5 Green 6, 7, 8 Blue Temperature in degrees Fahrenheit (tolerance 5F, 9, 10, 11 Green typical) 12, >12 Yellow Temperature in degrees Celsius (tolerance 3C, typical) Humidity as percentage (from 5% - 95% tolerance, 10 Five Function LEDs identify the measurement being digits) displayed (see B below).
