A multimeter device can measure resistance, current, AC/DC voltage, and it also can determine continuity on an electrical circuit, and its range for current, voltage and resistance is widely variable.

What does the two terminal test method measure?
Measures the resistance to earth from a grounding system
What does a megohmeter or megger test?
It checks resistance from a circuit or an electrical component to earth, to make sure it is electrically isolated. This must be a very high value of resistance, hence 'megohms'.
What is the difference between insulation resistance and earth resistance?
insulation resistance can be measured by means of megger, with built in d.c generator. It is measured between the conductor and the earth. earth resistance can be measured by means of earth resistance tester. For good effective earthing, th earth resistance should be of order 0.5 ohm
What should be the resistance value of healthy earth pit?
what is the resistance value of a healthy earth pit
How we get 0.5 ohm resistance for Earth pit?
Type your answer here... how to get ohm in earth pit
What instrument measures changes in the tilt of the earth?
A tiltmeter measures changes in the tilt of the earth. :)A tiltmeter is an instrument that measures changes in the tilt of the earth. :)
Which instrument measures and records vibrations within the earth and on the earth surface?
This is known as a seismometer or seismograph.
What instrument measures the amount of gravitational attraction between Earth and an object at rest on Earth's surface?
scale
What is a seismographer?
Earthquakes generate seismic waves which can be detected with a sensitive instrument called a seismograph.It is an instrument that measures vibration in the Earth.
What does the two terminal test method measure?
Measures the resistance to earth from a grounding system
What is mean by earth resistance tester?
I think it measures characteristics of soil to determine its suitability underneath a plant or substation. One way to measure resistance of the earth is with four conductors in a straight line -- the two outer ones inject a current, and the two center ones measure the voltage. From these two known quantities and Ohm's Law, R=V/I gives the resistance. Earth is not a great "earth," and electrical equipment and building designers strive for a resistance of one ohm. The earth seldom rarely complies with this.
What instrument measures the earth's rotation?
Depends what you mean by instrument but I guess the sun, mmon and stars are pretty good indicators to use.
What instrument measures how the force of gravity on Earth's surface differs from the force of gravity on the Moon's surface?
a spring scale

It checks resistance from a circuit or an electrical component to earth, to make sure it is electrically isolated. This must be a very high value of resistance, hence 'megohms'.
How Earth resistance meter works?
There are 3 terminals of an Earth Tester meter. Connect two terminals of meter to earth as far as cables can. Fix the two rods in to soil with the help of a small Hammer. Then connect two knobs of the meter with these rods.Connect the third terminal to the Earth Pit,to whom earth resistance is to be measured. The meter reading will indicate the resistance of the earth pit.The Best resistance of an earth pit must be under unity(<1). Answer BY: Naeem Ahmad Electrical Engineer.
What are the advantages of a good earth resistance value for an electrical system?
A good earth resistance value for an electrical system implies that, any persons making direct physical contacts with it are more secure from hurtful electrical current leakages that may, by fault, flow through it's outer metallic parts, and the system itself and the persons are again more secure from lightning heavy currents that might strike the system.
