The Tanita DC-430MA Body Composition Analyzer is a medical device designed for comprehensive body composition analysis. It is available in two versions: a remote display version and a column-mounted version. The device is clinically proven to be accurate, reliable, and provides highly repeatable results, making it suitable for use by health, research, and medical professionals worldwide.

Function Description

The analyzer measures weight and impedance, and estimates various body composition parameters using Bioelectrical Impedance Analysis (BIA). These parameters include:

Body Mass Index (BMI): A measure of body fat based on height and weight.
Total Body Fat Percent and Weight: The proportion and mass of fat in the body.
Total Body Water Percent and Weight: The proportion and mass of water in the body.
Total Body Muscle Mass: The mass of muscle tissue.
Physique Rating: An assessment of body type.
Bone Mass: The estimated mass of bone minerals.
Visceral Fat Rating: An assessment of fat surrounding internal organs, with a healthy range indicated.
Basal Metabolic Rate (BMR): The minimum energy required by the body at rest.
Fat Free Mass (FFM): The mass of the body excluding fat.
Metabolic Age: An indication of the average age associated with the user's metabolic rate.

The device is indicated for use with healthy children aged 5-17 years old and healthy adults with active, moderately active, to inactive lifestyles. It is designed for simplicity, allowing measurements to be taken in under 30 seconds.

Usage Features

Measurement Modes: Supports "Body Composition Mode" (with "Two step flow" or "One step flow" options) and "Scale Mode".
User Interface: Features an LCD display and intuitive keys for navigation and input.
Printer Integration: Includes a built-in printer for immediate output of measurement results. Paper is loaded by opening the printer cover and inserting a 10cm strip of paper.
SD Card Slot: Allows for storage of up to approximately 10,000 measurement results (weight only mode) on a 2GB SD card. Data is saved in a YYYYMMDD format.
ID Number Function: Can be set to automatically increment or manually entered.
Tare Value (Clothes Weight): Allows for input of clothes weight (0.0 to 10.0kg) to ensure accurate body weight measurement.
Body Type Selection: Users can select "Standard" or "Athletic" mode, which adjusts calculations for more reliable results based on activity levels.
Personal Information Input: Age (5-99 years) and height (90.0-249.9cm) are entered for accurate analysis.
Measurement Conditions: For accurate results, it is recommended to measure after sufficient rest, at least three hours after a meal, and at the same time of day under consistent conditions. Inner thighs should not touch during measurement, and transmitting devices like mobile phones should be avoided.
Leveling: The device includes a level gauge to ensure it is placed on a stable, level surface. Adjustable feet allow for precise leveling.
Data Output: Measurement results can be output to a PC via USB or RS-232C in CSV format.

Safety Precautions:

Warning: Failure to follow instructions may result in death or severe injury.
- Not for use with subjects with pacemakers or other mechanical implants due to weak electrical current.
- Do not handle the plug with wet hands.
- Keep away from flammable gas and oxygen-rich environments.
- Do not modify the equipment.
- Do not use a multi-plug adapter.
Caution: Failure to follow instructions may result in injury or damage to property.
