Statement of Measuring Accuracy
• This scale should be placed on hard, even surface firmly to ensure the best performance.
• Although it comes with carpet feet adaptors, it is not recommended to use on soft surface
such as carpet or rug.
(If you need to use it on soft surface, please refer to "USE ON SOFT SURFACE" section
for detail.)
• This scale uses BIA (Bioelectrical Impedance Analysis) to determine body fat percentage.
BIA is considered reasonably accurate for measuring groups, or for tracking body
composition in an individual over a period of time,but is not considered sufficiently
accurate for recording of single measurements of individuals.
As BIA is based on body water balance, your state of hydration can impact the level of
accuracy.
Overall the BIA provides an inexpensive, reliable way to estimate and track body fat level.
To receive the most accuracy, please do not measure body fat within 30 minutes after a
meal, or 120 minutes after an exercise.
It is recommended that you measure the same time of the day, preferably early evening
before a meal, for the most consistent results.
• Do not compare weight readings from one scale to another as some differences will exist
due to manufacturing tolerances.
• Do not use your Doctor's scale reading as "accurate" reference to determine the accuracy
of your scale, it is not the right way to test the scale accuracy. The best way test scale
accuracy would be using 50 kg+ (110 lb+) standard Olympic weight bars on the scale.
• If you weigh yourself twice and get two different results, your weight lies between the two
readings.

HOW DOES THE BODY FAT SCALE WORK?
This Surpahs Body Fat Scale uses Bio Impedance Analysis (BIA) technology which
passes a small electrical current through the body to estimate body fat mass, total body
water, muscle mass, and bone mass. The electrical current is very small and may not be
felt. Contact is made with the body via four stainless steel pads on scale.
NOTE: This device is a personal monitor and should be used in a consistent manner
for the most accurate readings. While readings of this analyzer might be different than
that of other scales (hydro-densitometry or hand held calipers), your changes in body fat
percentage shown by this scale will be reflected accurately.
IMPORTANT: The information provided by this device is NOT meant to treat, cure, or
prevent any disease or illness. This device should NOT be used by anyone who is acutely
or chronically ill, suffering from a disease, or taking medications that affect your water
levels. The accuracy of readings for these patients has not been verified. Specific medical
advice should be obtained from a physician.
CAUTION: This scale is NOT intended for use by pregnant women. Although the age range
of this scale is between 15 and 85, it is NOT intended for use by children under the age of 18.
It should also NOT be used by anyone with an implanted medical device (such as a
pacemaker, metal plates or screws; or contraceptive devices). If in doubt, contact your
physician.
This analyzer will work accurately as a scale for anyone, within the specifications and
warnings noted above, and give accurate body fat results for the majority of people.

BATTERY INFORMATION
This scale operates on 2 x CR2032 lithium batteries (pre-installed). Remove any plastic strips
from the battery compartment on the bottom of the scale before continue with these instruction.
Your scale has been set to measure in pounds (lb) and inches (in). To change the unit please
press the ‘UNIT’ button on the bottom of the.
When the screen displays “Lo”, it indicates power is low, please replace both batteries with t
he “+” signs up, do not combine old and new batteries.
The scale needs to be initialized (set up) before first use and after battery replacement.
USE ON SOFT SURFACE
1. Remove the non-slip pads from
the scales feet
2. Fit the extension
feet firmly onto the scales feet
To fit carpet feet
Attached four "Carpet Feet" are to help the scale to work on soft surface such as carpet or rug.
If you want to use the scale on soft surface, you may install these Carpet Feet to the scale.
NOTE:
Depending on the softness and thickness of a soft surface place, however the scale
weighting accuracy is not guaranteed by installing "carpet feet" to the scale.
Follow these steps to test if the soft surface is good for your scale with "carpet feet":
a). After all of the four carpet feet are installed, stand on/off the scale for a while a few
times.
b) . Make sure the scale is firmly placed.
c). Now you can make several weighting tests, if you notice that the results are a bit off,
this soft surface is not good for the scale, and you should move the scale back to
hard surface.

USING BODY FAT SCALE
In order to measure body fat and body mass index, you must first set up your profile by
entering your height, age and gender (in athlete mode if applicable) in the follow
“SET-UP PROCEDURE” steps. The scale uses these parameters to calculate your
measurements.
NOTE: Athlete mode calculates more accurate results for highly fit individual persons who
do 10 hours or more per week of aerobic activity and have a resting heart rate of 60 beats
per minute. The scale is not calibrated for professional athletes or body builders.
Bare feet are required for the weight/boy fat analyzer to function properly:
Remove your shoes and socks before beginning the measurement. In order to get the
most accurate and consistent result, wipe your feet with a damp cloth, leaving them slightly
damp before stepping onto the scale. It is recommended that you measure at the same time
of the day, preferably early evening before a meal, for the most consistent results.

2. It is recommended to measure body fat and weight daily at the same.
3. Use this product without clothing for best accuracy. Clothes can vary in weight and
affect the calculation.
4. Feet must be bare and clean. For best results, they should also be slightly damp.
TOTAL BODY WATER (TBW)
You must wait several hours before taking a body fat analyze when:
Drinking coffee or alcohol, taking diuretic medications, or exercising. These all affect your level
of hydration and the accuracy of your body fat analyze.

Body water measurement results are influenced by the proportion of body fat and muscle.
If the proportion of body fat is high, or the proportion of muscle is low, then the body water
results will tend to below.
It is important to remember that measurements such as body weight, body fat and body water
are tools for you to use as part of your healthy lifestyle. Since short term fluctuations can be
normal, we suggest that you chart your progress over time, rather than focus on just a single
day’s reading. Consult your physician to determine what is most ideal for you.
MUSCLE MASS
Muscle mass is important in determining a healthy body composition. A person with a higher
% of muscle mass finds it easier to move, but needs more energy to do it. Exercise is very
important in maintaining a healthy body and the muscle mass % is a useful indicator to
control it. The normal muscle mass percentage on the body weight lies between 38% and
54% for men and between 28% and 39% for women depending on age and physical activity
level.

BONE MASS
The bone mass readings given by this scale are estimation of the amount of bone in your
body. Individuals with osteoporosis or low bone densities may not get accurate. If you
have any concern regarding your bones, please consult your doctor.

AUTOMATIC MEMORY RECALL FUNCTION
The scale can automatically recall your profile number based on the last weight result once
personal data has been saved and a weight/body fat result has been taken.
1.Step on the scale platform and remain still while the scale computes your weight.
Your weight will appear.
2.When your weight is stored, a running zeros pattern (“0 0 0”) appears while the scale
computes.
3.If the scale successfully finds your profile number, the scale will display the body fat, water,
muscle, and bone results in order.
4.Note: The scale can only determine the correct profile number if no other user weighs
within +/-6.6 pound range. If another user is within the +/-6.6 pound range, the scale will
narrow down the profile number choices and display them on the screen.

TROUBLESHOOTING
1. You must have bare feet to take measurements. In order to get the most accurate and
Consistent results, wipe your feet with a damp cloth, leaving them slightly damp before
stepping on the scale. Repeat measurements again, maintaining maximum contact
between your feet and metal sensors.
2. The condition of the skin on the bottom of your feet can affect the results. The natural
effects of aging activity can make the skin hard. Take the reading with clean and slightly
damp feet for best accuracy.
3. WARNINGMESSAGE
---- =Overload Warning. The maximum weighing capacity of the scale
has been exceeded. Remove the weight immediately; otherwise,
permanent damage to the scale will occur.
Lo = Low Battery Warning. Replace the batteries. Always replace
both batteries at the same time, do not combine old and new batteries.
If only the weight is all that appears after the Bio Impedance Analysis (BIA)
was attempted, or you get instability Error, Contact Error, or Body Fat
Beyond Range Error, stand still on the scale while measuring. Clean
bottom of your feet with a damp cloth, leave slightly damp, and repeat
measurement again, maintaining maximum contact between your feet and
the four metal pads (sensors).
