IP4X compliantSupports measurement of ground resistance and ground voltage.
- Supports both the "three-wire" type for precision measurement and the "two-wire" type for simple measurement.
- The ground voltage measurement function can measure up to a maximum voltage of AC30V.
- Comes with an LED that allows you to check the correct grounding status.
- Comes with a backlight that allows measurements even in dark places.
- For power distribution lines, indoor wiring, electrical machinery equipment, and grounding copper rod construction sites.
How to use
Precision Measurement
Drive T-shaped auxiliary earthing rods into the ground in a straight line at intervals of 5 to 10 m from the grounded body to be measured (RX), and then connect the red and yellow probes to the T-shaped auxiliary earthing rods and the green probe to the grounded body to be measured (RX) to perform the measurement.Simple measurement
The measurement is performed by connecting the red probe to the existing grounding electrode (re) and the green probe to the grounded body to be measured (RX).. *Please wear protective insulating equipment when measuring or in areas where electric shock is expected around the object being measured.
