Product Description
This specialized instrument is used for measuring the grounding resistance of ground grids and the grounding continuity between grounding points.
It adopts frequency conversion anti-interference technology,does not require large current measurements,and can obtain accurate 50Hz data even in environments with strong interference,such as substations.Measurement results are displayed on a large LCD screen and can be printed outusing the built-in micro printer.The instrument can simultaneously measure grounding impedance and grounding resistance,providing a more accurate reflection of the actual characteristics of the ground grid.
1. Good power frequency equivalence
2. Strong anti-interference capability
3. High precision.The basic error is only 0.005Ω
4. Can measure the grounding resistance of current piles,voltage piles,ground grids,continuity resistance and resistance,and soil resistivity.When used with the dedicated frequency selective voltmeter,it can measure step voltage,transfer potential,and contact voltage with higher anti-interference capability and accuracy
5. Full English menu operation,directly displaying measurement results.
6. Low wiring labor:No need for large current lines.
