On completing this course, participants should be able to use installation tests (combi-meters) to document that an electrical installation meets the requirements of applicable regulations and norms.

Target group

Electrical engineers, fitters and trainees.

This course assumes that participants already have some basic knowledge of the norm. The course explains a number of terms and concepts and relevant requirements from part 6 of the norm – Verification.

Subjects covered in the course

Metering techniques associated with the requirements and practical use of the metering instrument. Practical training using different meter functions.
