Determination of surface insulation resistance of coated electrical steel sheets, punched parts and individual samples Measuring categories Quality control of insulation coating Resistance distribution Manual or fully automatic version Mechanical construction: pneumatic or hydraulic pressure generation Control and evaluation software Preparation and execution of the measuring process according to IEC 60404-11 measuring method A, ASTM-Standard A 717 and JIS (optional) Measuring Technology for Soft Magnetic Materials Surface resista

Franklin Tester FT 600 Operating principle Measuring the total current which flows through the insulation coating of the sample when pressure is applied via several contacts. Conversion of the measured value to an equivalent surface resistance. Especially suitable for quality control of insulation coating. The test head consists of two longitudinal rows of five vertically mounted steel rods which are free to move axially against the surrounding spiral springs. A stainless steel measuring contact is positioned at each end of each rod. It is possible to move the test head pneumatically or hydraulically...
