What is the purpose of compensating cables wires?
It is use for quick response reading meter/Accuracy.
What is the definition of multi-meter?
multi-meter is a measuring instrument. multi meter is available in two types. Digital and analog.multi-meter is a multi purpose measuring instrument.we can check resistence,voltage,current &contunuityof a cunducting wire. even we can check the diode,transistor.
What are shading bands and why are they provided in energy meters?
shading bands are used to increase the magnetic field in shunt magnet in single phase energy meter. They also used for reduce the friction error.
What is the purpose of vantage meter transducer package?
The vantage meter, sold by Snap-On is used for numerous automotive diagnostics. The transducer package is used for pressure measurements. (Fuel pressure, oil pressure, combustion chamber compression, manifold vacuum, etc.)
What is the purpose of the zeroing resistor in an ohmmeter and does it always accomplish its intended purpose?
A: There is no zeroing resistor the leads resistance are the zeroing resistor. there is however a pot where the zero can be accomplished by adjusting the current flow out of the meter to measure the voltage to determine the resistance. that pot is an adjustment to compensate for an old internal battery drift. If not changed periodically it may become a useless meter because zero cannot be achieved
What type of meter movement is used in most meters?
Most meters use a moving coil meter movement, which utilizes a coil of wire attached to a needle that moves in response to the current flowing through the coil. This movement is reliable and accurate for measuring various electrical quantities.
Why are moving iron test instruments not used with DC although they can work in DC?
For moving-iron instrument magnetic field is caused when the current (voltage) passes the fixed circle. When the current (voltage) passes the fixed circle，the two iron plates are magnetized ,rotational torque is resulted, the deflection angle indicate measured current. Because the magnetized polarity is same for AC or DC, moving-iron instrument can be used in AC and DC circuit. For permanent-magnet moving-coil instrument magnetic field is caused by the permanent-magnet, When the DC current passes the moving coil, rotational torque is resulted,so the deflection angle indicate measured DC current. As AC current passes the moving coil ,because inertia of moving parts of meter the deflection angle indicate rotational torque average, but rotational torque average is zero in cycle, moving parts of meter is´t deflec,so permanent-magnet moving-coil instrument only is used in DC circuit.
What is working of PMMC?
In PMMC meter or (D'Arsonval) meter or galvanometer all are the same instrument, a coil of fine wire is suspended in a magnetic field produced by permanent magnet. According to the fundamental law of electromagnetic force, the coil will rotate in the magnetic field when it carries an electric current by electromagnetic (EM) torque effect. A pointer which attached the movable coil will deflect according to the amount of current to be measured which applied to the coil. The (EM) torque is counterbalance by the mechanical torque of control springs attached to the movable coil also. When the torques are balanced the moving coil will stopped and its angular deflection represent the amount of electrical current to be measured against a fixed reference, called a scale. If the permanent magnet field is uniform and the spring linear, then the pointer deflection is also linear
The pointer of an analog meter is connected to?
Fixed magnet
Can a magnet slow down an electric smart meter?
No, a magnet cannot slow down an electric smart meter. Smart meters operate based on electrical measurements and are not affected by magnetic fields.
Why does the reading on a newton metre increase when a current passes through the coil?
When a current passes through the coil of a Newton meter, it generates a magnetic field around the coil. This magnetic field interacts with the permanent magnet inside the Newton meter, causing a torque to be exerted on the coil. This torque results in a deflection of the coil, which is then translated into a reading on the scale of the Newton meter.
What is the purpose of a gas meter?
The purpose of a gas meter is to monitor how much gas a particular house is using. Customers are then billed according to how much gas they have used from the meter.
What do most analog meters use to facilitate the needle movement?
Most analog meters use a coil of wire (solenoid) and a magnet to facilitate the movement of the needle. When current passes through the coil, it creates a magnetic field that interacts with the permanent magnet, causing the needle to move and indicating the measurement on the meter.
How does a moving iron meter works?

How can you tell a if you have a Meteor?
We might have a meter but we don't know how can we tell accept the magnet test
Can a magnet slow down an electric meter?
Yes, definately yes. The Magnet will pull the spinning disk on the electricity meter resulting for that disk to slow down and THE RESULT OF MONTHLY ELECTRICITY BILL will decrease 25%. Just place the magnet on both sides of the Electricity Meter then It will slow down. WARNING: Do not get caught by the Readers or you will busted for jail! WORKS ON ME! :D
