1.1 Overview and Features
Overview
The grounding works applied to the distribution lines and electrical
facilities are essential for preventing electric shock and fire as well
as for safeguarding the equipment. The instrument is an earth tester
that is fully functional for measuring earth resistance for grounding
works.
It is capable of providing accurate and highly reliable measurement.
The instrument can provide precision measurement (3-pole method)
and simplified measurement (2-pole method).
Features
High accuracy
The accuracy of the 200.0 Ω range is
±1.5% rdg ±4 dgt.
Auto-range and
auto-check for
auxiliary earthing
electrode
The measurement is performed by simply
pressing the MEASURE button. There is
no need for cumbersome range-switching.
In addition, the earth potential and auxiliary
earthing electrode are automatically checked.
High allowable
earth resistance for
auxiliary earthing
electrode
The resistance that the auxiliary earthing
electrode can tolerate is now about 10 times
higher than the conventional level. As a result,
it can provide measurement under adverse
conditions.
