Soil Resistivity checker

Know whether a soil resistivity traverse is good before you pull the pins. Type in your readings, or scan the field sheet, and Soil Check fits a layered soil model in about a second. It gives the RMS error and a plain verdict, and points straight at the reading that doesn't fit. Re-measure one point on the spot instead of sending a crew back. BUILT FOR THE FIELD • Wenner and Schlumberger (c = C1–P1, d = P1–P2) • Enter readings exactly as the meter shows them, with an optional range-multiplier (Factor) column • Spacing templates for 20 ft, 100 ft and metric traverses • Feet or metres; Ω·m or Ω·cm • Works offline, anywhere AN ANSWER, NOT JUST A NUMBER • Excellent (RMS under 5%), Good (5–10%), Acceptable (10–20%) or Redo (over 20%) • Log-log plot of measured apparent resistivity, the fitted curve and the soil model • Auto-fit tries one to four layers and adds a layer only when the data…
