Inserting/Replacing Batteries

  1. Open the battery compartment cover on the bottom side of the scales.
  2. Remove the depleted batteries.
  3. Insert new 4× 1.5 V AAA batteries. Make sure you observe the correct polarity. If batteries are protected by a safety film, remove it first before putting the batteries into the scales. Only use alkaline batteries of the same type; do not use old and new batteries at the same time; do not use rechargeable batteries.
  4. Close the cover.

Basic Weight Measurement (without BMI) / Changing Unit of Weight

  1. Place the scales on a flat, hard, and stable surface.
  2. Carefully step onto the scales – the scales turn on automatically. If you wish to change the unit of weight, repeatedly press the kg/lb/st button on the bottom side of the scale.
  3. Stand still on the scales and do not move – after a while, the measured weight will be displayed.
  4. Set the desired unit of weight by repeatedly pressing the kg/lb/st button.
  5. After 30 seconds, the scales turn off automatically.



WARNING: Persons using a pacemaker or another implant with electronic components are not allowed to use these scales – the proper functioning of the implant might be impaired.

NOTE: Correct measurements can only be achieved when standing evenly on the scales, barefoot, and with

  • dry feet! The basic principle of the device is measuring the electrical impedance within the human body. To obtain data, the scales send a weak, unnoticeable electronic signal through the body.
  • The signal is completely safe! The method is called „Bioelectrical Impedance Analysis“ (BIA), a factor based on the mutual relation between the body and weight and the associated percentage of water in the body, as well as other biological data (age, sex, body weight). There are corpulent people with a balanced ratio between fat and muscle mass and lean people with very high body fat values. Body fat is a factor that can significantly impact for instance the cardiovascular system. Therefore, checking both values (fat and weight) is a useful tool for maintaining good fitness and a healthy body.

Body fat is an important component of the body – it is key for protecting the joints, is also a source of vitamins, serves as a body temperature regulator, and overall plays a vital role in the human body. It is advised to not reduce its amount rapidly but to ensure it is at a healthy level, keeping a good balance between muscle mass and fat.

Visceral fat (or organ fat) is located in the abdominal cavity around and inside our organs. It serves as their protection. Visceral fat is hidden. The amount of visceral fat is not dependent on the amount of subcutaneous fat in the body. If we have excess visceral fat, it can be more dangerous than subcutaneous fat. Visceral fat is linked to hyperlipidemias (elevated levels of lipids in blood). These may lead to more serious chronic diseases, such as diabetes, or acute diseases such as heart attacks or strokes.


The human body is approximately 55–60 % water, with ratios varying based on age and sex.

Water has several roles in the human body:

  • Constitutes our cell blocks; meaning that every cell, such as skin cells, brain cells, and muscle cells, operates correctly only if they contain sufficient water.
  • It is an important substance released in our body.
  • It transports nutrients and metabolites in the body.

You can compare the reference values for your fitness profile with the following table. It shows the dependence of body fat on age and sex. Focus more on keeping a balance of water in the body. Similarly to fat levels, water levels fluctuate during the day. The obtain relevant results, make measurements always at the same time of the day. The obtained measurements for body fat and water should be taken rather as informative. They are not recommended for medical purposes. Always consult these measurements with your doctor before making radical changes to your regimen.Emos EV107 Digital Personal Scale with BluetootH-FIG 4
