100g calibration weight for testing the accuracy of your 100g digital scales.
If you've just purchased a new set of 100g digital scales, or suspect yours may be losing their accuracy, 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.
