all of tri vector meter is naot good
What is trivector meter?
a DC clamp meter works on the principals of what is called "Hall Effect." The meter creates a magnetic field, and the DC voltage passing through the wire interacts to crate a meter reading.
they work very well.
Disconnect and take the meter out. If it is a 120V meter, just connect it to a lamp cord and plug it in. If it still doesn't register, you have a dead meter. Sometimes they get stuck...you can tap on the face gently if nothing else works. Oh, and BE CAREFUL with that high voltage!!!
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.
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
trivector meters are used to measure kVAh and also kVA of maximum demand.it has a kwh meter and reactive kvah meter in a case with special summator mounted between them.

Q-meter works on the principle of Series Resonance
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..

A Creep Meter uses a wire stretched across a fault to measure horizontal movement of the ground.
they work very well.
Please refer to the answer as below
a creep meter measures vertical movement and a tilt meter measures horizontal movement. Hope my answer works for you thanks
