Why is my measured weight not accurate?

The scale will have measurement errors in soft and uneven places (such as carpet). Please put the scale on a hard/flat surface and step on the scale barefoot. Then the screen will light up.


1. Please check your personal information (gender, age and height) to ensure that your information is accurate. -Make sure that your scale is on a hard and flat surface. Some surfaces look flat but they are not. Try different hard surfaces.

2. Check the leg of the scale before measuring. If they are unbalanced, the data will be inaccurate. -Make sure to display “0.00” on the display before use.  Have your barefoott full touching the electrodes.

3. Stand firmly on the scale and do not shake your body when weighing.

Why do I need to turn on GPS for Android phones?

Android phone 6.0+ requires enabling location in order to use Bluetooth . The Android operating system requires it to search and sync with Bluetooth devices.

Caution: BLE scanning requires your permission to enable location because BLE scanning identifies objects that could be used for geolocation. Turning off location will disable Bluetooth.

How to switch units (kg/st/lb/st:lb)?

1. Confirm whether the scale supports unit synchronization with app.

Read the manual to see if the scale supports syncing with APP.

2. If the scale does not support unit synchronization, you need to set the unit on the APP and the scale separately.

3. If the scale supports unit synchronization, you can synchronize the setting information to the scale after setting on the APP. The unit after the scale is synchronized will usually take effect the next time it is powered on for measurement.

Why dose my scale display abnormal?

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.

If other conditions cannot be measured, please contact the purchaser.
