Megger DET2-2 MGR-DET2-2
The Megger DET2/2 Auto Earth Tester is designed for measuring earth electrode
resistance and soil resistivity. It uses the four terminal method of
measurement. The instrument is auto-ranging relieving the operator of any
concern as to which resistance range to use.
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).
Earth Resistance Range 0,010 to 19,99 k (auto-ranging), 1 m resolution.
Test Frequency: 105 to 160 Hz reversing d.c. (50 Hz operation default to 128
Hz, 60 Hz operation default to 150 Hz) Set in steps of 0,5 Hz
Test Current: 50 mA max (selectable high and low levels)
Maximum Output Voltage: < 50 V r.m.s.
Operating: -10 to +40C (14 to 104F)
Storage: -20 to +60C (-4 to +140F)
Operating: 90% RH max. at 40C (104F)
