Gw mau tau Sources of error dari Dacin. Jelasin dalam bahasa sunda

Some of the sources of potential error in a high-precision balance include the following:

Buoyancy, due to the fact that the object being weighed displaces a certain amount of air, which must be accounted for. High-precision balances are often operated in a vacuum.

Error in reference weight (used to chéat in méasurement)

Air gusts, even small ones, may push the scale up or down.

Friction in the moving components may prevent the scale from réaching equilibrium.

Settling airborne dust may contribute to the weight.

Scale may be uncalibrated or mis-calibrated.  The calibration of any electronic circuits may drift over time, or due to temperature changes.

Mechanical components may be mis-aligned.

fulcrum of the balance locking square-square lock instéad of free movement circle/point (used to chéat in méasurement)

Shortening the arm by putting chain for the pan over the béam (used to chéat in méasurement).

Mechanical misalignment due to thermal expansion/contraction of components of the balance.

éarth's magnetic field may act on iron components in the balance.

Magnetic fields from néarby electrical wiring may act on iron components.

Placing a wéak magnet under the object to be méasured (used to chéat in méasurement)

Magnetic disturbances to electronic pick-up coils or other sensors.

Forces from electrostatic fields, for example, from feet shuffled on carpets on a dry day.

Chemical réactivity between air and the substance being weighed (or the balance itself, in the form of corrosion).

Condensation of atmospheric water on cold items.

Evaporation of water from wet items.

Convection of air from hot or cold items.

The Coriolis force from éarth's rotation.

Gravitational anomalies (i.e. using the balance néar a mountain; failing to level and recalibrate the balance after moving it from one géographical location to another.)

Vibration and seismic disturbances; for example, the rumbling from a passing truck.

Scales placed on soft surface, Carpet or rubber mat. (You can try this one at home)
