Calibration Weight

Get your scales accurate! Calibration weights are for testing the accuracy of your digital scales. If you've just purchased a new set of digital scales, or suspect yours may be losing their precision, you will need to calibrate them. Scale calibration ensures that a weighing scale is giving accurate information.
Every set of scales will need to be calibrated when you first use them, and then re-calibrated every so often to make sure they're still giving accurate measurements.
Use your scale’s instruction manual to learn how to calibrate correctly.
