Kyoritsu-4200 Earth Clamp Tester

The Kyoritsu 4200 Clamp Tester is capable of measuring ground resistance levels between 0.05 and 1500 Ω without the use of additional probes in multi-ground systems. With large jaws designed to clip directly into a specific test application, kyoritsu earth tester 4200 can measure AC current. Accurate RMS phase or leakage currents can be calculated from 0.1mA to 30mA to provide important information about the grounding network.

With a built-in filter function, the Kyoritsu-4200 can remove electrical noise for accurate results. These results can also be stored directly on the instrument, with built-in memory for 100 readings. Other unique features of this earth resistance clamp meter include a buzzer function, data hold, and a backlit LCD display. for the kyoritsu 4200 prices contact us, and for the kyoritsu 4200 pdf click on the datasheet link.

Frequency Asked Questions

How do you check earthing with a clamp meter?

Earthing is the process of connecting a system to the ground. A clamp meter is an instrument used to measure the resistance between two points of an earth circuit. The most common use of a clamp meter is to test the earth in order to see if it has been done correctly. The two points are usually at either end of the earth wire and one point should be connected to the earth, while the other point should be connected to a metal object.

How does an earth clamp tester work?

Earthing is the process of connecting a system to the ground. A clamp meter is an instrument used to measure the resistance between two points of an earth circuit. The most common use of a clamp meter is to test the earth in order to see if it has been done correctly. The two points are usually at either end of the earth wire and one point should be connected to the earth, while the other point should be connected to a metal object.

kyoritsu 4200 has two metal clamps that are used to connect with the ground. The kyoritsu multimeter is connected to an ammeter and voltmeter, which then measures the electric potential difference between two points on the earth’s surface.

How do you 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 internal probe three to nine feet closer to the grounding rod. Test the resistance again. If the result is within 30 percent of the first reading, your test is ready. 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.

What are P and C in earth tester?

The 3-point method, called the “potential drop” method, consists of the ground electrode to be measured and two other electrically independent test electrodes, usually labeled P (potential) and C (current).

What happens if earthing is not proper?

If earthing is not done properly, there are a number of potential health risks. These include:

• Immune system suppression
• Increased inflammation
• The altered circadian rhythm
•  Increased risk of cancer
