General Instructions
Transtek Body Fat Analyzer GBF-1251-B1 applies BIA (Bio-impedance Analysis)
technology. A small amount of weak current flows through the human body so as to detect
the bio-impedance and estimate BMI, body fat, body water, muscle mass and bone mass.
The electrical current is small and may not be felt.
This BIA technology is cheap, safe, non-invasive, toxic-free and harmless. It also
possesses the characteristics of simple operation and abundant information.
The current mentioned above is less than 0.5mA. However, please be aware that
anyone with an wearable or implantable medical electronic instrument, such as a
pacemaker, must avoid using this device.
The intended use of this device is for healthy children 10-17 years old and healthy adults.

Start MeasuringInitial Start-Up
Initialising Your Scale
1. Press the platform centre and remove your foot.
2. “0.0” will be displayed.
3. The scale will switch off and is now ready for use.
This initialisation process must be repeated if the scale is moved.
At all other times step straight on the scale.
Weight Only Operation
Your TRANSTEK Body Fat Analyzer will operate as a conventional
weight - reading scale. No special programming steps are required.
Once the scale is initialized, as previously described, you may simply step on
the scale to measure your current weight. For only weight reading.
1. Position the scale on a flat, hard
surface. Carpeted or uneven
floors may affect accuracy.
2. Step onto the scale platform
and remain still while the
scale computes your weight.
3. The scale will display your
weight value.
4. The scale will automatically
turn off after a few seconds.
First Measurement
Please process the user setting before your first measurement.
(Refer to Set Up Your Profile for more details)
STEP 1: Step on the platform barefooted.
STEP2: Stand still and the weight data will be locked
with the unit stop blinking.Keep full contact
with the electrodes until the LCD stop displaying
moving “ ”.
STEP 3: The measuring results will be displayed
sequentially four times:Weight,BMI, Body

Health Tips - About Body Fat
Fat is essential for human body. It can not only store energy and protect viscera, but also
regulate body temperature and maintain normal physiological function of human body.
However, too much body fat is harmful to human body. It is always accompanied by Fatty
Liver, diabetes, coronary heart disease, etc.
Therefore self-measuring and self-monitoring body fat level are beneficial to your health.
Since we can’t judge body fat level simply by our weight, this body fat analyzer
GBF-1251-B1, with BIA (Bio-impedance Analysis) technology applied, is an accurate
device that offers a quick and comfortable way to obtain your body fat level.
EMC Guidance
1. MEDICAL ELECTRICAL EQUIPMENT needs special precautions regarding EMC and
needs to be installed and put into service according to the EMC information provided in
the ACCOMPANYING DOCUMENTS.
2. Wireless communications equipment such as wireless home network devices, mobile
phones, cordless telephones and their base stations, walkie-talkies can affect this
equipment and should be kept at least a distance d = 3,3 m away from the equipment.
(Note. As indicated in Table 6 of IEC 60601-1-2:2007 for ME EQUIPMENT, a typical cell
phone with a maximum output power of 2 W yields d = 3,3 m at an IMMUNITY LEVEL of
3 V/m)
