As a VOM (volt-ohm meter) is one type of electrical measuring instrument, it is unclear how to answer this question. It is almost as if you had asked "What are the advantages and disadvantages of the banana as compared to the edible plant part?"
A multimeter is a common instrument used to measure electrical current. It can measure current, voltage, and resistance in electrical circuits.
The official definition of the word bolometer is "a sensitive electrical instrument for measuring radiant energy."
A comparator is a measuring instrument used to compare the dimensions of a workpiece to a standard reference. It typically consists of a dial or digital indicator, a magnifying lens, and a measuring probe. Comparators are commonly used in manufacturing and quality control to ensure the accuracy and precision of machined parts.
A low resistance ohmmeter is used
An instrument for measuring in volts the differences of potential between different points of an electrical circuit.
A voltammeter is a type of scientific instrument used for measuring electrical quantities. These are measured in two SI units: the electric potential (volt) and the electricity's quantity (coulomb).
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
It measures the current.
An instrument used for measuring a quantity of something is called a measuring device or a measuring instrument. Examples include a scale for measuring weight, a ruler for measuring length, or a thermometer for measuring temperature.
A pelvimeter is an instrument for measuring the pelvis.
