How do you recalibrate a Weight Watchers electronic food scale?

To recalibrate a Weight Watchers electronic food scale, first ensure the scale is on a flat, stable surface. Turn the scale on and wait for it to display "0.0" before placing a standard weight or calibration weight on the platform, if available. If the scale does not read the correct weight, refer to the user manual for specific recalibration instructions, as the process may vary by model. Finally, remove the weight and check if the scale returns to zero; if not, repeat the calibration steps.
