EARTH TESTER FT6031-03

Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The FT6031-03 is a IP67 dustproof and waterproof two- or three-pole ground resistance tester with large, easy-to-read display, highly sensitive earthing rods, and innovative cable winder that significantly reduces the amount of time needed to complete earth resistance tests.

CAT IV 100 V, CAT III 150 V, CAT II 300 V

Dustproof and waterproof enclosure for robust performance in the field

IP67 dustproof and waterproof

Since the FT6031’s enclosure is designed to keep out dust, it can be used with peace of mind in settings where it would be exposed to mud and dust. And if the instrument gets dirty, it can be rinsed clean with water.

Using a grounding resistance meter: Two- and three-pole methods

You can select from two grounding resistance measurement methods (two-pole or three-pole).
The instrument switches the internal connection automatically when the selection key is pressed, so there’s no need to connect a short bar or other fixture.

Three-pole method:
Measure grounding resistance after inserting supplemental grounding rods into the ground.

Two-pole method:
Measure grounding resistance using the Class B ground of a pole-mounted transformer.

Dramatically faster measurement setup thanks to superior ease of use and digital operation

The FT6031’s supplemental grounding rods are thinner than previous products, making it easier to insert them into, and remove them from, the ground. The rods are made of rigid, corrosion-resistance stainless steel. In addition, the allowable resistance of the supplemental grounding electrodes has been increased by a factor of 10. This enhancement eliminates the inconvenience of setting and resetting the rods over and over again when the allowable resistance is exceeded, for example in dry soil conditions.

Digital grounding resistance meter featuring easy operation

The FT6031 is extremely easy to operate: just press the MEASURE key.
The instrument will automatically complete the following sequence of operations:
ground potential check → supplemental grounding electrode check → grounding resistance measurement.
Auto-range operation eliminates the need to switch ranges since the instrument automatically selects the optimal range.

Newly developed cord winders keep measurement cords from getting twisted or tangled

When measuring grounding resistance, it takes time to put away the long measurement cords.
Hioki’s newly developed winders can rewind cord about twice as fast as the reels used in previous products, dramatically reducing the amount of time needed to clean up after measurement.
