1 Introduction
We are very pleased to offer a high quality, professional grade test instrument, for
carrying out four wire Earth Resistance measurements, as well as specific ground
resistance measurements on which the estimation of earthing quality is based. The
equipment was designed and produced based on many years experience of producing
and dealing with Earth Resistance and Electric installation test equipment.
1.1 General description
The Earth Tester is a professional, hand
–held, battery powered test instrument. It is
intended for carrying out Earth Resistance measurements in accordance with
International standard IEC 60364-6-61 (VDE 0100 Teil 610) and European standard
EN 61557 - 5.
The instrument is supplied with all of the basic accessories necessary for carrying out
the tests.
The electronic section of the Earth Tester is produced in SMD technology, which
