1 Begin by placing the sensor on a nger free of deformities. It is best to use the ring or
middle nger of your non dominant hand. It is recommended to not use nail polish for
best accuracy and repeatability of consistent measurements. Blue and Green nail polish
signicantly affect the accuracy of the measurement. Always use the same nger for every
measurement. To ensure proper placement:
• The cable should be on top of your hand in a straight line as far as possible.
• Your nger should be all the way in the sensor
• Use the same posture and remain still during measurement
Taking a Measurement

8
2Once you are ready, tap the Start button within the app. The measurement time varies
and can range from 60 to 90 seconds. Be patient, the system will ask you to try again if
it cannot get a result within 120 seconds.
• During testing be sure to not move around
• Refrain from talking, coughing, or sneezing during measurement
• During the measurement, a question related to the activity will be displayed.
Please be sure to answer all activity questions to allow you to get better data
reviewing power in your graphs.
3Your measurement result values will display on the screen. When you tap the Capture
button, the numbers displayed will be saved in your history. The gauge to the right of
the display tells you your target range based on your age and biological sex. You can
customize the target range based on your individual goals by accessing the Options tab
of the app.

Hgb and Pr - Descriptions
Hemoglobin (Hgb)
Is the protein contained in red blood cells that is responsible for delivery of oxygen to
the tissues. The Ember device will display values between 10 - 24 g/dl
Pulse Rate (Pr)
The number of times your heart beats per minute as monitored from the pulsations at
your ngertip. The Ember device can measure a range from 25 - 240 bpm.

11
Range Adjustment
The normal ranges displayed on your results screen
can be adjusted within the Options area of the
Ember app. The default values are from published
sources on general population ranges based on
biological sex and age.
We recommend you set your own custom ranges
on input from your trainer or your own personal
knowledge or goals.

12
• Externally applied coloring (such as nail polish)
• Any substance containing dyes, that change usual blood pigmentation may cause
erroneous readings.
• Electromagnetic Interference (EMI) from items such as computer displays and/or
LCD TVs
• High intensity lights (including pulsating strobe lights and sunlight) directed on the
sensor
• Hemoglobin synthesis disorders, Hemoglobinopathy, Vascular disease
• Elevated Bilirubin, Carbon Monoxide (CO) and/or Methemoglobin (Met)
• Low arterial perfusion or low arterial oxygen saturation levels
• Moving or talking during a measurement
• Improperly placed sensor on nger
• Using the sensor on a deformed nger
Inaccurate readings can be caused by:

If you take a measurement and receive the phrase
Low instead of a numeric value for Hemoglobin, it
indicates that your value was below 10 g/dl and
is too low to present a number. If you receive the
phrase High instead of a numeric value, it indicates
that your value was above 24 g/dl and is too high
to present a number.
If your Pulse Rate result has a red box behind it the
value is out of your set ranges. These ranges can be
adjusted to your specic needs in the Options area
of the App.

Incomplete Measurement
If you take a test and receive the incomplete popup
dialogue, please check the following and try your
measurement again.
• Reduce excessive motion or interference to
the device and sensor during test.
• Check sensor placement, reduce ambient
light, and remove nail polish
• Use a nger with no deformities or nail
abnormalities and always use the same nger.
• Make sure your hands are not cold by
rubbing your hands together vigorously for
10 seconds.

Reviewing Features
A very exciting feature about the Ember device is the ability to review your historical
data in different ways. The more you participate, by measuring frequently and choosing
activities associated with each measurement, the more powerful your graphs become.
We recommend you measure 3 times per day. Using these activities: 1st of day, Pre
Workout, and Post Workout.
Explore and enjoy graphs by using pinch to zoom, pan and even rotate your device to
take advantage of landscape view. Graphs can be shared via SMS, email, and popular
social networking sites to share your progress with friends, coaches, trainers, and
teammates.
Sharing test results can be done one at a time or by sharing all results from the history
table view. To share all results, tap the share button a .csv le can then be sent via email.

Activities
17
Every time you take a measurement, the app will ask you to associate an activity
with your measurement. By using a consistent nger and by practicing consistency in
your measuring technique, along with associating measurements with activities, this
will allow you to have a more powerful and precise historical review of your data.
Consistency is vitally important to get reliable trends in Hemoglobin.
We recommend measuring the rst thing every day before you get out of bed. We
also recommend measuring 5 minutes before a workout and then 1 minute Post
Workout. All of the graphs and tables in the History tab allow you to lter your
measurement data by the activities associated with your measurements. For example,
if you always take a measurement right after a heavy training session around the
same time every day and associate that measurement with “Post Workout”, then you
can observe the historical trend just for those measurements.
