It is connected across the hot and neutral if it's voltage is 120 volts. There are two terminals on the back of a panel mount frequency meter. Line voltage to one terminal and the neutral wire to the other terminal. The working voltage will be on the meter's nameplate which is usually located on the side of the device.

It's an instrument through which frequency of a signal can be determined
A frequency meter is needed to test for frequency. Some of the upscale process meters have the ability to test for frequency.
An Amp Meter
Units for Frequency are Hertz (Hz) Hertz is also known as s-1 (1/seconds) There is no distance component (meters) in frequency, only a "time" component
frequency meter is used to measure the frequency of unknown frequency signal.
pressure coil or voltage coil across the supply and the current coil in series.
That will depend on the setting of the meter switch and the circuit connected to the component (if there is one).
How do you connect an ammeter to a circuit?
polarity is of major importance in dicect current circuits. <<>> When using meters please remember that a volt meter does not connect into a circuit, the leads are placed across the component that you are measuring. It is an amp meter that connects into the circuit, becoming part of the circuit, to measure the current flowing through that circuit.
Besides not dropping it, you prevent damage to a multimeter by never connecting it to a circuit that it is not intended to measure. Two examples... If you are in a 0.6 milliamp range you would not want to connect the meter to a 6,000 volt focus pin in a television set. If you are in ohms mode, you would not want to connect the meter to a circuit that has voltage present.
A voltmeter uses the principle of Ohm's law, which states simply that the amount of current that flows in a circuit is equal to the voltage applied divided by the resistance of the circuit. Therefore, if one were to connect a known resistance in series with a meter across a voltage source, then the meter deflection would be proportional to the current flow and hence the voltage. The meter is calibrated in volts so that the test voltage can be read directly. The meter used in a voltmeter is very sensitive, typically 50 micro-amperes so that it does not affect the reading by its load on the circuit. pizza is good when volts don't go thru!!
how connect a variable resistor to circuit
what is resonant frequency
Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
when the frequency is increased the total impedance of a series RC circuit is decrease.
