Megger DET2/2 Auto Earth Tester
The MEGGER® DET2/2 Auto Earth Tester is a robust compact
instrument designed for measuring earth electrode resistance and soil resistivity. It uses the four terminal method of measurement which eliminates
the resistance of the current circuit from the measurement. The circuit design
ensures that the resistance of the potential circuit does not affect the
measurement during practical testing.
The maximum output voltage is limited to 50 V for safety when
performing a test and convenience when re-positioning test spikes. The
instrument is auto-ranging relieving the operator of any concern as to which
resistance range to use. The low service error and an IP 54 environmental
specification enable accurate results to be obtained in ‘unfriendly’ testing
conditions.
The DET2/2 Earth Tester is a reliable instrument designed for
larger or more complex earthing systems, including communications earthing
systems and difficult testing environments. It may be used to test in
accordance with BS 7430 (1991), the IEE Wiring Regulations and VDE 0413 part 7
(1982). The instrument is suitable for soil resistivity measurements, which
are used to establish the optimum electrode design and site, as well as
perform archeological and geological investigations.
Resistivity tests assist in the design of a correct earth
system and avoid the cost of re-working electrode installations. Earth testing
kits, which include suitable test spikes and test leads, are available
separately.
