Scale is not powering on
Try replacing the old batteries with a fresh pair of CR2032 batteries. If your scale is new, ensure that the plastic insulation tab is removed from under the batteries. If the issue persists, please contact us for further assistance.

How to remove the batteries
Use an item such as a paper clip, pin, sewing needle, etc to pry out the batteries from the battery compartment. Use the "channel/hole" as indicated below to position your item to pry out the batteries.

Touch controls do not register
Ensure the scale surface is clean and residue-free. Always keep the scale at room temperature for the best performance.

Scale fluctuations
The number may fluctuate because it is constantly recalculating a very sensitive measurement while the system is still stabilizing. The scale itself and the measurement process are not perfectly static. There may be other factors that contribute to the phenomenon.
- Sensor noise
The load cell inside the scale converts force into an electrical signal and that signal is never perfectly stable. Electrical noise causes small variations.
- Micro-vibrations you can't perceive
You may not see movement, but the scale can feel it from building vibrations (footsteps, traffic, HVAC systems, etc), table or floor flexing, or even nearby equipment running. Highly sensitive scales amplify these small disturbances.
- Internal settling of the scale
When weight is applied, the load cell slightly deforms. It takes time to fully "creep" into a stable state. This is called "mechanical creep" and can cause slow weight drifting.
- Temperature effects
Even small temperature differences can cause expansion/contraction in the load cell and drift in electrical components. This can make the reading slowly change even with no motion.
- Digital rounding and display refresh
Digital scales are sampling continuously rounding to a display value and updating multiple times per second. You would typically see a live stream of slightly different measurements, not one fixed value.
- Resolution versus stability tradeoff
If your scale shows very precise increments (e.g. 0.01 or 0.1 grams), it will always look less stable. A less precise scale may not be as noticeable (scales that weigh greater or equal to 1 gram increments).
Overall, if a scale fluctuates within a small range, this is normal operation. If there is continuous drifting upward/downward, it could be calibration, surface, or a temperature issue. Please remove the batteries for 5 minutes and reinstall to check if the scale will stabilize.
