Description
The model “4610” is described as a digital ground resistance and soil-resistivity tester — i.e., used for measuring earth/ground resistance (2-point, 3-point) as well as soil resistivity (4-point method).
It is auto-ranging (the instrument selects the measurement range automatically) and intended for field use (rough environment).Key Specifications & Features
From the user manual and spec sheets:
-
Measurement Ranges: 0.00Ω up to 1999Ω (20Ω / 200Ω / 2000Ω ranges)
-
Resolution: 10 mΩ on the lowest range; 100 mΩ and 1 Ω on higher ranges.
-
Accuracy: For example for 20Ω range: ±2% of reading ±1 count. Test current: 10 mA, 1 mA, 0.1 mA depending on range.
-
Safety: Withstand 250 VAC with spikes to 3000 VAC or 1000 VDC.
-
Indicators / warnings: It has LED indicators to show high input noise, high auxiliary rod resistance, faults in connections.
-
Case/Build: Heavy duty ABS case, sealed against dust/water (in one spec IP50).
-
Usage methods supported: 2-point, 3-point, 4-point (soil resistivity) tests. Also supports step-voltage and touch-potential measurements.
