Frequently Asked Questions

This message indicates that the scale has lost its calibration or the load cell may be damaged. Try calibrating your scale using the steps in the user manual first. If calibration does not work, contact our warranty department for support.

Calibration is performed at the factory and many users will not need to calibrate for quite some time. If your measurements require maximum accuracy, we recommend purchasing calibration weights for your scale and checking accuracy from time to time, calibrating when needed. If you are using your scale several times a day and weighing close to full capacity, you may need to calibrate monthly or quarterly. If you only weigh occasionally and keep your scale well protected, you may only need to calibrate once a year or less. Always use trusted calibration weights. Do not use arbitrary items like coins or canned goods to calibrate. Only calibration weights are accurate enough for calibration precision scales.

Scale accuracy will depend on several factors including your scale's readability, environmental conditions, and calibration just to name a few. Accuracy will degrade over time as components wear down. Check our support articles for more in-depth information on scale topics including accuracy.

Readability is the smallest increment of the scale's display. To use a wristwatch analogy, readability would be the smallest increment of time discernable on the dial (typically 1 second), but it is not the same as accuracy. Check out our article on sources of error for information on different factors affecting accuracy.

This is the instability warning. Try using the scale in a more stable location. Check out our scale support articles for tips on obtaining the best results with your scale.
