DescriptionThe Desco Analog Surface Resistance Test Kit is a portable battery-powered instrument designed to measure resistance point-to-point (RTT) and surface to ground (RTG). The meter is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 10E5 ohms.ESD protected area products should be tested:A. Prior to installation to qualify for listing in user’s ESD control plan. Approved ESD materials (see product qualification table at ANSI/ESD S20.20-2007 Table 3 EPA ESD control items)B. During initial installationC. For periodic checks of installed products as part of ANSI/ESD S20.20-2007 Compliance Verification testing per ESD pliance 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 the 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.” (ANSI/ESD S20.20-2007 section 7.3)The Analog Surface Resistance Meter and its accessories are available as the following item numbers:Figure 1.

DESCRIPTION

The UCx907 family of load share controller ICs provides all the necessary features to allow

multiple-independent-power modules to be paralleled such that each module supplies only its proportionate share

to total-load current.

This sharing is accomplished by controlling each module’s power stage with a command generated from a

voltage-feedback amplifier whose reference can be independently adjusted in response to a common-share-bus

voltage. By monitoring the current from each module, the current share bus circuitry determines which paralleled
