Digital ground resistance tester CA6460 @CA6460%

Digital ground resistance tester CA6460, formeasurement of grounding resistance and soil resistivity.Grounding resistance measurement range of 0 to 2000 Omega, the automatic range design, automatically switch to the best measurement range. Rugged CA6460 housing, simple operation, can be a variety of measurement, is the ideal choice for electricalmaintenance personnel. The mechanical index and safety index (such as: impact test, vibration test, drop test etc.)conforms to the IEC standard. Because of the high anti-interference design, which is suitable for various complex and bad environment (such as the existence of the effect of high stray current measurement accuracy).

Product features:

Soil resistivity measurements (4 pole)

Measurement of grounding resistance (2 pole or 3 pole,potential drop method)

Automatic range function: automatic selection switch to the best range

Highly resistant to noise and interference Design

Simple operation: wiring - key - Reading

Instrument panel with three LED lights, indicating: input disturbance voltage is too high, the auxiliary pileresistance is too large and the wiring error

Power: the use of 8 1.5V LR14 dry cell

Solid shell, dustproof, waterproof (IP53)

But the connection point of grounding circuit conduction(continuous) test

Terminals with different color design, convenientconnection identification

Product application:

Using the 3 electrode method measuring grounding andgrounding resistance, typically used to disconnect the ground connection conductor occasions

Using the 4 electrode method for measurement of soil resistivity, soil resistivity minimum position, make thegrounding engineering is more reasonable, economy
