The answer is all of them
All test equipment has to be calibrated. It is calibrated when it comes from the manufacturer but depending on how much the test equipment is used recalibration is usually recommended.
Test equipment is calibrated against a standard of some sort that is stable. In many cases these standards are traceable to the standards at the National Institute of Standards and Technology (NIST) in Maryland.
Through the use of a 'multiplier', i.e. a carefully-calibrated resistor connected in series with (in the case of an analogue instrument) the instrument's operating coil.
1 - cross section of of the tank and the height can be calibrated. 2 - With a gallon of fluid in the reservoir was built and calibrated.
the most accurate calibrated torque wrench was using the TWT torque wrench tester products that produce by Stahlwille. Its also called transducer.

an 'ammeter'
a calibrated instrument for measuring the potential difference between two points.
When the pH is measured with a calibrated instrument it is a quantitative measurement.

The TC on calibrated instruments indicates the temperature coefficient, which shows how the instrument's accuracy may change with temperature variations.

Odometer is an instrument that can measure miles or kilometer depending on how it is calibrated
By using a precise instrument. One that is calibrated by a recognised body.
If you calibrate something it means that you mark an instrument with a scale of readings. To calibrate something also means that you compare the scale with a known scale of another instrument. This insures something is accurate.
