Frequently Asked Questions (FAQs)

1. What is calibration weights?

Calibration Weights are used to check the reading of scale, to make sure it is still accurate. They used when calibrating a scale. While the calibration states how a scale behaves, adjustment of the scale changes its behavior.

2. How do you calibrate a weighing instrument?

To calibrate a digital scale, set it on a flat surface and choose a weight. Turn the scale on and go into calibration mode. Put the weight on the scale and wait for it to calculate the total weight. If the weight is off, hit the calibration button and wait for it to recalibrate.

3. What can I use for 50g calibration weight?

Coins as Calibration Weights Coins are minted to precise specifications, including weight, so they can serve as calibration weights. For example, a U.S. nickel weighs 5 grams. A penny weighs 2.5 grams. These numbers easily multiply, so 10 nickels can serve as a 50-gram calibration weight.
