How to use the Tanita UM-014 scale?
Frequently Asked Questions - 01/02/2026
Response Notice-Facile

To properly use the Tanita UM-014 scale, follow these simple steps:

1. Device Installation

  • Place the scale on a hard, flat, and stable surface, such as a tiled or wooden floor.
  • Avoid soft or uneven surfaces like carpets or rugs, which can distort the measurement.

2. Power On

  • Gently step on the platform with your foot to turn on the device.
  • The screen will light up and display numbers or symbols for a few seconds.
  • Wait for the screen to display "0" to indicate that the scale is ready to use.

3. Weight Measurement

  • Step slowly and carefully onto the platform.
  • Remain still during the measurement to ensure an accurate reading.
  • Your weight will be displayed on the screen after a few seconds.

4. Reading and Units

  • The weight is usually displayed in kilograms (kg) or pounds (lb), depending on your device's settings.
  • To change the unit, refer to the specific model options (usually via a dedicated button), if available.

5. Auto Shut-off

  • After a few seconds of inactivity, the scale will automatically turn off to save battery.

Tip: To obtain consistent measurements, always weigh yourself under similar conditions, for example at the same time of day and in comparable clothing.

How to resolve the error message displayed after selecting from memory on the TANITA UM scale?
Frequently Asked Questions - 07/01/2026
Response Notice-Facile

The error message "ERROR" that appears on your TANITA UM scale after selecting from memory has several specific causes that you can easily resolve.

Main cause: SET button not released properly - When you press the SET button to confirm your memory selection, you must release it immediately. If you keep the button pressed, the device will display "ERROR" after 3 seconds. Make sure to press and then quickly release the SET button after selection.

Secondary cause: premature stepping on the scale - The error also appears if you step on the platform before the screen displays the numbers "0.0". After pressing SET and confirming your memory selection, the device beeps and displays your programmed data, then beeps again before showing "0.0". Absolutely wait for this "0.0" display before stepping on the scale. If you step on too early, you will be unable to take a measurement.

Additional checks - Before repeating the operation, ensure that you have selected the correct memory number that corresponds to your profile (gender, age, height, athlete mode or standard adult). Also check that your personal data is correctly recorded in this memory. Stand barefoot, with clean and dry feet, properly placed on the electrodes of the weighing platform.

Battery status - If you simultaneously see the message "Lo" (low battery), immediately replace the AAA batteries. Worn batteries can cause malfunctions of the memory function. Your settings will remain saved when replacing the batteries, and you will not need to reprogram your data.

Complete reset if the error persists - If the problem continues after checking all these points, turn off the scale, remove the batteries for at least one minute, then reinstall them and turn the device back on. This reset clears temporary errors from the system. Then repeat the entire procedure, ensuring you release the SET button immediately and wait for the "0.0" display before stepping on.

How to change the measurement units on the TANITA UM scale?
Frequently Asked Questions - 15/12/2025
Response Notice-Facile

On your TANITA UM scale, changing the measurement units is very simple thanks to a switch located at the back of the weighing platform. This scale offers three measurement units: kg (kilograms), lb (pounds), and st-lb (stone-pounds).

Change procedure:

  • Turn the scale over and locate the switch on the back of the weighing platform
  • Set the switch to the desired unit: kg, lb, or st-lb
  • The scale will now use this unit for all weight displays

Important: changing the unit also affects the height programming mode. If you switch to pounds (lb) or stone-pounds (st-lb), the height will be automatically programmed in feet and inches. Conversely, if you select kilograms, the height will be expressed in centimeters.

There is no need to press buttons or access a menu: the physical switch is sufficient to make the change instantly.

Thank you for selecting a Tanita Body Fat Monitor/Scale. This model uses the BIA (Bioelectrical Impedance Analysis) technique, a state-of-the-art technology for body fat assessment.

Safety Precautions

  • Persons with implanted electronic medical equipment, such as a pacemaker, should not use the Body Fat Monitor feature on this Tanita Body Fat Monitor/Scale. This Body Fat Monitor/Scale passes a low-level electrical signal through the body, which may interfere with the operation of a pacemaker.
  • The Tanita Body Fat Monitor/Scales are intended for home use only. This unit is not intended for professional use in hospitals or other medical facilities; it is not equipped with the quality standards required for heavy usage experienced under professional conditions.
  • Do not use this unit on slippery surfaces such as wet floors.

Important Notes for Users

This Body fat monitor is intended for adults and children (ages 7-17) with inactive to moderately active lifestyles.

It is not intended for people with athletic body types. Tanita defines "athlete" as a person involved in intense physical activity of approximately 10 hours per week and who has a resting heart rate of approximately 60 beats per minute or less.

People with athletic body types should use Tanita Body Fat Monitor/Scales equipped with Athlete mode.

This scale is not intended for pregnant women, professional athletes or bodybuilders.

Recorded data may be lost if the unit is used incorrectly or is exposed to electrical power surges. Tanita takes no responsibility for any kind of loss caused by the loss of recorded data.

Tanita takes no responsibility for any kind of damage or loss caused by these units, or any kind of claim made by a third person.

Note: Body fat percentage estimates will vary with the amount of water in the body, and can be affected by dehydration or over-hydration due to such factors as alcohol consumption, menstruation, illness, intense exercise, etc.

PRINCIPLES OF ESTIMATING BODY FAT PERCENTAGE

Tanita Body Fat Monitor/Scales allow you to determine your body fat percentage at home as easily as you measure your weight.

What is Body Fat Percentage?

Body fat percentage is the percentage of fat in your body. Too much body fat has been linked to conditions such as high blood pressure, heart disease, diabetes, cancer, and other disabling conditions.

TANITA UM - What is Body Fat Percentage? - 1
Body Fat Ranges for Standard Adults 1,2

Based on NIH/WHO BMI Guidelines.
As reported by Gallagher, et al, at NY Obesity Research Center. To determine the percentage of body fat that is appropriate for your body, consult your physician.

The BIA Method

Tanita Body Fat Monitor/Scales use the BIA (Bioelectrical Impedance Analysis) technique. In this method, a safe, low-level electrical signal is passed through the body. It is difficult for the signal to flow through fat in the human body, but easy to flow through moisture in the muscle and other body tissues. The difficulty with which a signal flows through a substance is called impedance. So the more resistance, or impedance, the signal encounters, the higher the body fat reading.

TANITA UM - The BIA Method - 1

Tanita's patented "foot-pad" design sends a safe, low-level electrical signal through the body to determine its composition.

Hydraion Fluctuations

Hydration levels in the body may affect body fat readings. Readings are usually highest in the early waking hours, since the body tends to be dehydrated after a long night's sleep. For the most accurate reading, a person should take a body fat percentage reading at a consistent time of day under consistent conditions.

Besides this basic cycle of fluctuations in the daily body fat readings using BIA, variations may be caused by hydration changes in the body due to eating, drinking, menstruation, illness, exercising, and bathing. Daily body fat readings are unique to each person, and depend upon one's lifestyle, job and activities.

GETTING ACCURATE READINGS

TANITA UM - GETTING ACCURATE READINGS - 1
Heels centered on electrodes

TANITA UM - GETTING ACCURATE READINGS - 2
Toes may overhang measuring platform

Note: An accurate reading will not be possible if the soles of your feet are not clean, or if your knees are bent or you are in a sitting position.

To ensure accuracy, readings should be taken without clothing and under consistent conditions of hydration. If you do not undress, always remove your socks or stockings, and be sure the soles of your feet are clean before stepping on the measuring platform. Be sure that your heels are correctly aligned with the electrodes on the measuring platform. Don't worry if your feet appear too large for the unit - accurate readings can still be obtained if your toes overhang the platform. It is best to take readings at the same time of day. Try to wait about three hours after rising, eating, or hard exercise before taking measurements. While readings taken under other conditions may not have the same absolute values, they are accurate for determining the percentage of change as long as the readings are taken in a consistent manner. To monitor progress, compare weight and body fat percentage taken under the same conditions over a period of time.

TAKING WEIGHT AND BODY FAT READINGS

After programming your personal data you are ready to take a reading.

Select Personal Data Number

Press the Up button turn on. Use the Up/Down buttons to select your Personal data number. Press the Set button to confirm. (Release the key within 3 seconds or the display will show "Error".) The unit will beep and the display will show the programmed data. The unit will beep again and the display will show "0.0". Now step onto the platform.

Note:

  • If you step onto the platform before "0.0" appears the display will show "Error" and you will not obtain a reading. Furthermore, if you do not step onto the measuring platform within about 60 seconds after "0.0" appears, the power is shut-off automatically.
  • When using the "Up" button to turn the unit on, the personal data number last used will appear first.
  • Numbers that are not pre-programmed are automatically skipped.
