DET-2000, in your browser Beta

Plant the test spikes, wire the four terminals, pick a range and press TEST. See why the potential spike must be in the right place, and measure soil resistivity with four spikes.

Beta, just for fun. This is a playful beta, for illustration only. It is not a training tool and not a substitute for the real instrument. The actual DET-2000 can differ in appearance, display, button behaviour, ranges, timings and readings. Everything here is simulated, so do not use it to judge a real measurement. Always follow the instruction manual and your site safety procedure.

How the DET-2000 works

  • Earth electrode (3 wire): join E1 and P1 and connect them to the electrode under test. P2 goes to a potential spike and E2 to a current spike driven into the ground further away. The tester pushes current through E1/E2 and measures the voltage at the P spike.
  • Why spike position matters: the measured value changes as the P spike moves. Between the electrode and the far spike there is a flat plateau, around 62% of the way for a small electrode, where the reading equals the true earth resistance. Plant the spike too close or too far and the reading is wrong. The graph shows this live.
  • Soil resistivity (4 wire): plant four spikes in a line at equal spacing a and wire them E1, P1, P2, E2. Soil resistivity is ρ = 2π × a × R, averaged to a depth of roughly a.
  • Ranges: the switch selects 10 Ω or 1000 Ω. Use the 10 Ω range for low-resistance earths to get resolution; if the value is above the range the display shows an overload "1".
  • Accuracy: ±3% in the first and last 10% of the range and ±1.5% in between, as in the specification.

This is a training simulation. Terminals are shown as E1, P1, P2, E2 as in the specification. The usual convention is E1 and P1 to the electrode, P2 to the potential spike and E2 to the current spike; check the instruction manual for your instrument. The ground is an idealised model (hemispherical electrode in uniform soil), so real readings will differ, and the exact button behaviour of the physical instrument is approximated. Never use an earth tester on a live system.
