Weights which have been carefully measured and crafted for the specific purpose of calibrating scales should be used in scale calibration. These weights need to be of a known weight in order to adjust the scale.
Calibration weights are used to weigh things. They come in masses such as a 100g or 500 weight. They are used to exactly and accurately measure objects. They are placed on a scale and are then used to weigh the object.

Scales used to measure weight include: * Spring scale - measures the increased length of a spring as it stretches * Balance scale - uses a horizontal lever to compare unknown weights to that of known weights
Digital pocket scales are commonly used for business, shipping, cooking, and more. You should calibrate your scale every 4-5 times you use it, to make sure you get accurate readings. You can calibrate your digital pocket scale by cleaning it and following the calibration steps with weights, coins, or household items.

You will need more than just one nickel. Most scales require you to calibrate with a specific weight, usually a weight that is close to the scales capacity (ie 500g weight for 500g capacity scale) Nickels weigh approximately 5g so you would needs lots of them. However it is not exact and you will sometimes find nickels that weigh 4.9g to 5.1g. Nickels should only be used as a last ditch effort to fix a scale that is way out of calibration. You can find cheap calibration weights for pocket scales online.
The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.
Calibration standards are used to record the accuracy of certain calibrations that are performed. The accuracy allows the user to find out how good the calibration was.
Absolute instruments are rarely used except in laboratories and for scientific work.The quantity to be measured will be given in terms of deflection and the constant of the instrument.No calibration is needed in this type of instruments.Division on the graduated scale will not have any value marked on it. example:tangent galvanometer
the Richter scale
A: The only calibration that a potentiometer is allow to do is on the resistance scale. The reason being is the internal battery looses capability with age so to compensate the pot. will change current available to make the ohmmeter to go to zero when the probes are shorted. To test a volts range then an accurate voltage must be used to verify calibration.
