Instrumentation

Precision is also known as

In measurements, the sum of a set of numbers divided by the total number of pieces of data in the given set is called

The deviation of a reading from the expected value

Errors due to frictions of the meter movement, incorrect spring tension, improper calibration or faulty instruments:

Errors in analog meter reading due to physical position with respect to the meter scale

An instrument or device having recognized permanent or stable value that is used as a reference

The smallest change in a measured variable to which an instrument will respond

What is the basic unit for measuring current flow?

An instrument used to detect and measure the presence of electrical current is generally called

What is the most common type of meter movement?

A permanent-magnet moving-coil instrument

An instrument which depends on current in one or more fixed-coils acting on one or more pieces of soft iron, at least one of which is moveable

What is the device, which depends on the action of a movable permanent magnet, in aligning itself in the resultant field produced by a fixed permanent magnet or current-carrying coils whose axes are displaced by a fixed angle?

Measurement of high dc-voltages is usually done by using

Measuring instrument that can be used only to measure voltages

This instrument measures temperatures by electric means, especially temperatures beyond the range of mercury thermometers

This instrument refers to that one, which measures the intensity of the radiation, received from any portion of the sky.
