Frequently Asked Questions

InBody technology is different than that used in other BIA devices:

- InBody technology relies on direct measurement and can measure the body segmentally.
- InBody technology is capable of accurately measuring impedance in the trunk.
- InBody uses multiple frequencies.
- InBody does not use empirical estimations in calculating values.
- InBody can evaluate a wide range of body types, from extremely obese, to elderly, to athletic.

– The use of multiple frequencies to accurately measure intracellular and extracellular water.
– 8-point tactile electrode system with thumb electrodes providing a direct and reproducible measurement.
– Segmental impedance measurements to include accurate lean body mass measurements of the trunk.
– No empirical estimations required.

Using multiple frequencies improves accuracy and precision. At a single and low frequency, it is difficult for electrical currents to penetrate the cellular membrane and assess intracellular water. As frequencies get higher, the electrical current is more capable of penetrating the cellular membrane and accurately measuring intracellular water.

Adhesive tape electrodes are usually placed on the wrist and a fingertip. Voltage line and current flow line always overlap from a certain point, and that point is where measurement begins. However, it is almost impossible to place adhesive electrodes in the exact same place every time, thus the measurement starting points can differ. Rather than adhesive tape electrodes, InBody devices use tactile electrodes. Voltage line and current flow line overlap at the same point and allow for a secure and reproducible measurement starting point for each individual.

How does the InBody derive body fat measurements from body water measurements?

Body water volume is closely related to fat free body mass. When fat free mass is subtracted from total weight, body fat mass remains.

InBody devices use direct segmental measurement bioelectrical impedance analysis (DSM-BIA) to precisely measure body composition by sending multiple electrical currents through the body, resulting in up to six different impedance readings for the trunk and each of the four limbs.

The innovative in-depth analysis of the InBody Test yields accurate results for body composition outputs, such as body fat mass, skeletal muscle mass, (segmental) lean body mass, and percent body fat.

Impedance is the frequency-dependent opposition of a conductor to the flow of an alternating electric current. Impedance is composed of two main properties, resistance and reactance.

InBody provides segmental impedance values at varying frequencies to allow for accurate analysis of the human body. Since reactance is the interrupting force of alternating current flow, it increases in proportion to the integrity of cell membrane. Therefore, reactance and phase angle decrease when the number of cells is low or the cell membrane is more permeable or unhealthy.

The more water there is, the lower the impedance.

Historically, BIA technology, devices, and results have been met with some degree of skepticism. However, InBody technology addresses these concerns with its technological features and provides great precision and accuracy for total body and segmental measurements.

For more information, please read InBody Technology.

Other methods of measuring body composition include DEXA, hydrostatic weighing, air displacement, and anthropometric calipers.

The volume of a cylinder, in this case the body, changes when the height of the cylinder changes. BIA devices consider the body as a cylinder and the volume of body water is calculated with the height and impedance of the body.

Weight and body water changes can occur with the introduction of meals and fluids, or with a change in environment. Circulation of body water may also cause changes in water distribution throughout the day. It is recommended that repeat tests be performed under the same testing conditions, in the same environment, and at the same time of day as the initial test.

All InBody models accurately measure weight and body composition. Other outputs and technical specifications differ by model. These differences are highlighted on the main product page.

InBody recommends regularly scheduled maintenance of your Body Composition Analyzer every12-24 months, depending on the frequency of use, to maintain optimal testing performance.
We recommend scheduling maintenance service if:

- It has been over 24 months since your purchase
- Your InBody undergoes high daily usage
- Your InBody has been unused for over 4 months
- Your InBody is frequently moved to different locations
- Your InBody is experiencing weight measurement fluctuations

The InBody Maintenance Service includes:

- Board Functionality
- Cable Functionality
- Electrode Functionality
- Program Update
- Hardware Modification (if available) Fine Tune Calibration
- Weight Calibration
Thorough exterior and interior cleaning

Some of the maintenance services vary depending on the region.

InBody devices do not have a defined life expectancy. As long as you take good care of the device, you can continue to use your InBody device for many years. There are functioning InBody units greater than 10 years old.

What can I use to disinfect the InBody?
Wear disposable gloves and use 70% (or above) Isopropyl Alcohol Wipes to disinfect the InBody while paying special attention to the hand electrodes, footplate, screen, and any other part of the device that is frequently touched.
To prevent damage to the device:

- Do not spray or pour liquids directly on your InBody device.
- Do not immerse any part of the InBody device in liquid.
- Do not use cleaning agents composed of quaternary ammonium components such as benzalkonium/benzylalkonium chloride, which may cause discoloration and corrosion.

The standard warranty policy is 1 year from the purchase date for all InBody products. Extended warranty is available at the time of purchase, and you may be eligible to purchase an extended warranty if the product was purchased within a year. The warranty does not cover any physical and/or cosmetic damage, which includes any type of water damage. Other fees will apply for additional services such as loaner units and expedited shipping.

The InBody device has an auto-calibration function that is completed each time the device is turned on. It is not necessary to calibrate the InBody device unless there have been circuit board replacements. Load cell calibration should only be performed when weight measurements seem incorrect.

If the device freezes randomly on the main screen:
Try unplugging the USB cord that connects the InBody to the printer. Sometimes, garbage values can cause the InBody program to freeze. You will need to purchase a separate filter for the InBody and printer.

If the unit is freezing during the warm up process:
Please contact us for support.

Try turning the unit off and then back on. Do not stand, press, or leave anything on top of the base of the scale while the unit is warming up.
Go to SETUP to make sure that there is not a weight adjustment setting made to your unit.
If none of the above resolves the issue, please contact us for assistance.
