• 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.

Frequency Asked Questions

what is Earth Resistance Tester?

The Earth Resistance Tester is designed to measure the resistance of the object being tested. The Earth Resistance Tester is an instrument that measures the electric field strength between two points on a conductor. The Earth Resistance Tester can be used to detect faults in power cables, underground cables, and overhead cables. It is also used to test insulation materials and also for testing insulation systems such as lightning arresters and surge arresters. The Earth Resistance Testers are available in various ranges depending on the application or purpose that it will be used. for kew 4105a price please contact us.

How to Use an Earth Tester?

• Step 1 Locate the grounding rods outside of your home. Look for a metal pole that goes into the ground and has a wire running to your house. The bars are usually located near the foundation of your home. Disconnect the ground wire from the stick.

• Step 2 Insert two grounding probes into the ground parallel to your grounding rod. Place one probe 65 feet from the ground rod and the second probe 33 feet from the first probe (98 feet from the ground rod).

• Step 3 Attach the ground tester leads to the ground rods. The red wire connects to the outdoor probe, the white wire to the indoor probe, and the blue (or green) wire to the ground rod.

• Step 4 Turn on the ground tester and press start. Digital ground testers provide a resistance measurement. Make a note of the number.

• Step 5 Disconnect the probes and move the indoor probe three to nine feet closer to the grounding rod. Test the resistance again. If the result is within 30 percent of the first measurement, your test is complete. Otherwise, move the probes further away from the ground rod until you get two readings within 30 percent of each other. Note the distances you used for your readings.

• Step 6 Repeat resistance checks at least once a year. If the resistance increases more than 20 percent from your original reading, you should replace your ground bar.
