Tanita Scale Error 7 New Page

In hybrid scales (weight + impedance), mechanical shock (e.g., dropping the scale) can micro-fracture the strain gauge’s Wheatstone bridge. The resultant DC offset injects a common-mode voltage into the BIA front-end amplifier (typically an AD5933 or similar), saturating the analog-to-digital converter and corrupting the reference reading.

Remove the batteries from the scale for at least to fully reset its memory. tanita scale error 7 new

If the scale was dropped during shipping, the internal load cells or the wiring connecting the electrodes to the motherboard may have been jarred loose. In hybrid scales (weight + impedance), mechanical shock (e
