SOLUTION

The voltmeter is not an integrating instrument.

Integrating Instruments:

The instruments which add up the electrical quantity, i.e electrical energy, and measure the total energy (in kilowatt-hours) or the total Amper hours (in ampere-hours) supplied to a circuit in a given period are called integrating instruments.

In such instruments, there are sets of dials or gears which register the total quantity of electricity or the total amount of electrical energy supplied to a circuit in a given period. The Household energy meter is an integrating instrument. The Ampere-hour meter is another example of integrating instruments.

Recording Instrument: The recording instruments are those instruments that give a continuous record of the variations of the electrical quantity to be measured.

Example: The example of such an instrument is Recording voltmeters which are used in power stations to record the generated voltage.
