There are several possibilities:
1.LED not displaying: Check that the battery still has power by reinstalling the battery. If the LED display still does not work, try putting in a new battery.
2.LED displays LO (LOW BATTERY): Check to see that the battery is correctly installed, and make sure the battery still has power. Reinstall the battery, and if the LO display still appears, replace the battery with a new one.
3. LED displays ERR (ERROR): If only temporary, maybe it is calibrated by the scale itself. If for long time, the scale sensor may have been overloaded or even damaged Avoid exceeding measurements of 396 lbs (180 kg) when using this scale.
4. Check your profile information (gender, age, and height). Make sure your information is accurate.
5. Ensure your scale is on a hard/flat surface. Some surfaces seem flat but not. Try a few different hard surfaces.
6. Check the legs of the scale before you measure. If not balanced, the data won’t be accurate.
7. Make sure that ‘0.00’are shown on display before each use.
8. Step on with bare feet, with each foot touching both the top and bottom electrode.
9. Stand on the scale firmly. Do not shake your body when weighing.
10. Take your measurements at the same time each day to ensure the most accurate results.
If, after trying the above methods, the scale still can not display the weight correctly. Please contact your seller for further help.
