Doppler Radar can detect the signature of a tornado's rotation in a storm, but we usually need an eyewitness report to confirm that the tornado has actually touched down. Dual polarized Doppler radar can detect debris from a tornado, but that requires that the tornado is fairly strong and that there is enough debris for the tornado to pick up.

Doppler radar is used to predict tornadoes when they're already occurring.But aside from that tornado predictions are very uncertain and difficult to make. The durations of tornado warnings are counted in minutes and even then there are many false alarms.
There is no particular instrument used for measuring tornado intensity. Ratings are based primarily on damage assessment. Occasionally doppler radar has measure wind speeds inside a tornado, but such measurements are rare.

Instrument leak test procedures vary depending on the type of instrument. It is very common to use either air or a liquid under pressure to check the instrument for leaks.
Tornadoes are usually detected using Doppler radar.
The first documented use of the word "tornado" was in 1556.
A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.

Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
