Digital Ground Resistance Tester - Model Number 250200
The DET2 four-terminal, digital ground tester
addresses the broadest range of ground testing applications of any
instrument currently available. This unit's advanced features make
it ideal for testing large, complex grounding systems in difficult
testing environments such as those found in substations and
switchyards. It can be used for fall-of-potential and slope method
testing, as well as soil resistivity measurement to map for
ground-bed site selection.
In addition to its 40 V peak-to-peak interference
tolerance feature and 0.001 W resolution, the DET2 has matchless
added capabilities that make it virtually undefeatable in field
testing in the worst electrical environments. These features
include an interference filter (on/off) and test current control
(high/low). Most importantly, the test current frequency is
adjustable in half-hertz increments over the full range from 105 to
160 Hz. If soil transients are affecting the measurement, the
display alerts the user. The operator need only dial to a different
test frequency away from the troublesome harmonic while observing
the warning disappear and the reading stabilize.
