4200 Clamp type grounding resistance meterDetailed product description：

4200 clamp type grounding resistance meter detailed information

Only applicable to multiple points, which together can form a grounding body for the circuit.
No auxiliary grounding pile is required, only one clamp is needed to test the grounding resistance.
Test the grounding resistance between 0.01 and 1200 Ω.
The measurable leakage current for grounding is 1mA to 30.0A.
To ensure accuracy, internal microprocessor technology and special clamp head technology are used.
To ensure the correctness of the testing method or the reliability of the testing site, the LED will display
Symbols such as "JAW OPEN" and "Noise" (exceeding 3A).
Can record 99 sets of data.
Data retention function.
Large display screen and backlit display.
Battery level display and automatic shutdown function.
Designed to comply with international safety standards IEC61010-1 CAT.IV 300V
CAT.III 600V。
