Earth Resistance Tester

Basic measurement functions

• Earth resistance measurement (RE) Measurement method: 3-pole method, 4-pole method

Measuring range: 0.02Ω ~ 1999Ω ; Minimum resolution: 0.01 Ω ; Basic accuracy: 5%

• Soil resistivity measurement (ρ)

Measurement range: 0.01Ω • m ~ 376.8KΩ • m ; Interval of auxiliary earth rods, setting range: 1.0 m ~ 30.0 m. • AC true RMS voltage E.V Measurement range : 0 ~ 50V AC bandwidth: 40Hz ~ 200Hz Measurement basic accuracy : 2%

2. Earth test other features 

Earth resistance measurement adopts square wave excitation test, the maximum open-circuit voltage is 50Vp-p, and the short-circuit current is <3mA. 

Automatic range detection in earth resistance measurement. 

RK resistance test, the line resistance effect can be removed. 

Earth comparison test, the measurement result can be evaluated by the preset "pass/fail (✓ / ✘)" limit and be given audio alarms accordingly.

3. Product calibration

By connecting with the standard instrument, calibrating panel according to the procedures and saving the appropriate calibration data, the periodic calibration is completed and the due accuracy and performance of the product are guaranteed.

4. Large LCD display with white LED backlight.

5. Easy man-machine operation, portable, solid and suitable for field use
