Remove all batteries from the back of your scale. Leave the scale without its batteries for at least 10 minutes. Make sure that the battery compartment is clean, and the contact terminals are free of debris or residue. Check that the batteries have the correct polarity and reinsert them firmly in place.

First, turn the power on, then press the “Zero” or “Tare” button if there is one present. Wait patiently while the scale clears any remaining data from previous uses. It may take a second, but your scale should show a “0.00” weight once it is zeroed.
