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.
