AE-780A Surface Resistance Meter

Product Description : 

The AE-780A Surface Resistance Checker is a portable battery powered checker fitted with built-in parallel electrodes that allow for tests of material surface resistance. This meter is designed for quick checks of surface resistance for ESD control applications in electronics manufacturing or handling environment. The Surface Resistance Checker is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 1 x 10E5 ohms. Two banana jacks and an electrode toggle switch allow for the connection of two external 5 pound electrodes that measure surface resistance point to point (RPP) or resistance to equipment ground (RTG).

Compliance 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 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.

GENERAL GUIDELINES.

• • Use both 5 pound electrodes for RPP.
• • Use one 5 pound electrode and one lead to groundable point for RTG (note: groundable points are usually snaps installed on the material or workstation common point ground).
• • Ensure that the item being measured is electrically isolated (i.e. placed on an insulative surface) as the checker will measure the lowest resistance path.
• • Ensure that the test leads are separated as a best practice.
• • When using the 5 pound electrodes.
• • Place no closer than 2” from the edge of the surface being measured.
• • Place no closer than 3” to any groundable point.
• • Place the 5 pound electrodes about 10” apart for RPP of worksurface and 3’ for floor.
• • Preferred placements include: most commonly used surface portion, most worn, center, and furthest from groundable point.
• • For RTG, connect the banana plug to groundable point.
• • If surface has sections (floor tiles, garment panels), for RPP place the 5 pound electrodes on different sections.

ARMEKA expressly warrants that for a period of one (1) year from the date of purchase ARMEKA Surface Resistance Checkers will be free of defects in material (parts) and workmanship (labor). Within the warranty period, a credit for purchase of replacement ARMEKA Surface Resistance Checkers, or, at ARMEKA’s option, the Surface Resistance Checker will be repaired or replaced free of charge. If product credit is issued, the amount will be calculated by multiplying the unused portion of the expected one year life times the original unit purchase price.
