OL
Xiaomi OL on Mi Body Composition Scale: over measuring range
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
The Mi scale shows OL, sometimes flickering, when the load on it is outside its 150 kg measuring range. Step off, clear the platform and weigh again with only the intended load, on a hard flat floor and after letting the screen switch off first.
Safety first
Stop and check this first
- The Xiaomi manual says not to step on with a wet platform or wet feet or on the edge, because of fall risk, and the FAQ puts the maximum supported weight at 250 kg.
- Per the manual, measured data are for reference only and not medical advice, and the scale is not recommended with pacemakers or other medical implants; for any health worry, speak with a doctor.
Safe checks you can perform
- Step off, clear the platform and let the screen switch off
- Check the floor and that the scale sits flat
- Reset the scale after moving it

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Query to Xiaomi's official service
What they doIf OL shows with a free platform on a hard flat floor, Xiaomi service looks at the case with the scale model.
They must show youthe OL notice with an empty platform and the floor and reset tests already done.

Review of where the scale sits, with the technician
What they doThe technician checks the floor, the contact of all four feet and the calibration after a change of place with you before blaming the scale.
They must show youthe scale resting with no rocking and a weigh-in after the screen reset.
In writingwhich floor and position were used and what the test weigh-in showed.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Step off, clear the platform and let the screen switch off
- Who:
- you, with nothing on the scale.
- How:
- step off, remove any object from the platform and wait for the screen to switch off by itself before weighing again, as the FAQ advises. Step back on with only the load you mean to measure and watch whether the OL symbol flickers again.
- Result that matters:
- a weigh-in with no flickering OL symbol.
- If OL is gone:
- the earlier load was outside the 150 kg range and there is nothing more to check.
- If OL appears with an empty platform or a small load:
- carry on with the floor check and repositioning.
- Evidence to keep:
- a photo of the screen with the notice and a note of the load that was on the scale.

Check the floor and that the scale sits flat
- Who:
- you, with the scale in its usual place.
- How:
- set the scale on a hard flat floor such as tile or wood and avoid carpets, blankets or foam; Xiaomi says that on soft or uneven ground the data come out inaccurate and different. Check that all four feet rest on the floor and none is lifted.
- Result that matters:
- a steady scale on solid ground, with no rocking when you step on.
- If it was on a soft surface:
- move it and weigh again.
- If the floor was already hard and flat and OL stays:
- go on to restarting the scale after moving it.
- Evidence to keep:
- a photo of the scale in place and the floor type.

Reset the scale after moving it
- Who:
- you, once it sits in its final spot.
- How:
- if you moved it or it sat unused, Xiaomi suggests stepping on until the screen lights up, then waiting for it to switch off by itself before weighing again; the Body Composition Scale 2 FAQ says the sensor calibrates automatically when the screen goes off.
- Result that matters:
- a later weigh-in after calibration with no OL notice.
- If the notice is gone after the reset:
- avoid moving the scale during daily use.
- If OL persists with an empty platform:
- contact Xiaomi service.
- Evidence to keep:
- a note of the date and whether the scale had been moved before.

What it means
The Mi Body Composition Scale user manual (model XMTZC02HM) and Xiaomi's FAQ explain that, during weighing, the OL symbol means the weight is outside the scale's measuring range, which is 150 kg. It is a device notice about the load, not an interpretation of your data, and it does not replace a medical opinion: if something about your health worries you, talk to a doctor. Other models may differ and the notice alone does not prove a sensor is faulty.

Symptoms and causes
Probable causes · in order
- Load above the 150 kg measuring rangeCommon
The manual and FAQ say OL appears when the weighed load exceeds the top measuring range of 150 kg; the FAQ adds that the maximum supported weight is 250 kg.
Evidence: Manual de usuario de Mi Body Composition Scale (XMTZC02HM) · Preguntas frecuentes sobre la báscula de composición corporal Mi · Mi Body Composition Scale FAQ
- Weighing after moving the scale or long disuseLess common
Xiaomi warns that after the scale is moved, or left unused for a long time, the reading can come out off and advises ignoring it and repeating; the FAQ does not tie this explicitly to OL.
Evidence: Mi Body Composition Scale FAQ · Mi Body Composition Scale 2 FAQ
- Resting on carpet, blanket, foam or uneven floorLess common
Xiaomi's FAQ says soft or uneven ground gives inaccurate and differing data; it does not link this expressly to OL, but it is a point worth checking.
