9 STEPS FOR PERFORMING A MEASUREMENT
17 18
The KHACHIK CHECK scanner is a sophisticated device, which takes over 1000
measurement points per single measurement. The calculation of the result
needs significant computing power, which cannot be done on the scanner itself.
Therefore, the app sends the encrypted data via internet to a central server for
calculation of the result. The calculated result is then transferred to the app in the
same fashion. Typically, the phone/tablet will automatically choose an internet
connection. It may use an existing WIFI network or a cellular connection to send
the data to the server.
For the communication between scanner and phone/tablet, the scanner connects
to a WIFI hotspot. The phone/tablet must use a WIFI connection to the hotspot to
receive the measured data from the scanner.
Since a phone/tablet can handle only one WIFI connection at the same time
the app may need to change the WIFI connection between connecting to the
scanner and connecting to the internet several times.
The connection data are stored in the app, so changing from the scanner WIFI to
the WIFI used to connect your phone to the internet does not require you to enter
passwords or network names. But depending on the version of operating system,
you will be asked for permission (iPhones and Android 10 and newer phones
typically ask for permission, older phones may not).
9 STEPS FOR PERFORMING A MEASUREMENT
Once you have established the communication between the scanner and
your phone/tablet, you can conduct measurements without going through the
connection procedure again. If you always use the same scanner, you only need
to open the app, switch on the scanner, and select on the app your preferred
measurement mode.
The connection procedure between scanner and phone/tablet is described
below. Please read the manual of your phone/tablet if you do not know how to
connect it with the internet.

STEP 9 requires you to enter the name of the scanner’s WIFI by scanning the
QR-Code of the scanners serial number (see backside of the scanner) or by
typing in the serial number manually as shown in STEP 10/STEP 10.1. When
connecting a scanner to a phone/tablet, the app may download a firmware
update automatically if necessary as shown in STEPS 11 - 14.
Some of the steps are alternative steps and are displayed only when necessary.
The connection process is fast and simple and should, for the most part, be
performed only once, if you always use the same scanner.
The connecting operation is easy and supported by the KHACHIK CHECK app.
Switch your phone/tablet on and start the app now. When opening the app
for the first time, a “ Setup wizard ” is opened automatically (If you want to run
the setup wizard again, you can find it in the main menu by pressing the 3-bar
symbol on the top left side of the app). Please follow the instructions step-by-step
until you can select and start a measurement.
The following screen shots displays the connection procedure of the “
Setup
Wizard ”. Starting a measurement procedure is described in Chapter 9.2
The image of STEP 1 (see next page) is displayed on the phone/tablet when the
KHACHIK CHECK app is opened the first time after downloading. The additional
steps follow in the pictured consecutive order. The app will request you to switch
the scanner on STEP 7 .
When switching the scanner on while charging the battery or when the battery
has been charged before and the scanner is still connected with a USB cable,
the status indicator lights white, and one symbol of the progress indicator lights
red ( see Figure 3 on pg.16 ). Under this condition, the scanner does not open
its WIFI. Please disconnect the USB cable if you want to begin measuring. If the
device is not switched on, the battery will not hold a charge. In this case, please
charge the battery ( Ch. 8 ).

If you wish to connect a different scanner with your phone/tablet after you have
previously connected a another, please press on the 3-bar symbol in the upper
left corner of the KHACHIK CHECK app to select and start the “ Setup wizard ”
manually (Figure 4) . Follow the instructions to connect the additional scanner
now with the phone/tablet. The Setup wizard will guide you to an app page for
selecting and starting a measurement.
ATTENTION
ATTENTION
Please note that the KHACHIK CHECK app stores only the last connection data.
Therefore, you must conduct the connection setup again when you have connected
an additional scanner with your phone/tablet or if you wish to reconnect with the first
scanner once again. Every new scanner requires a new connection setup process.
Before you measure the first time please read the general recommendations
for a correct measurement listed in Chapter 10 “Measurement Basics”.
Following the rules of this chapter is essential towards effectively obtaining
a correct result.
Figure 4
Sign
To carry out the following steps, the KHACHIK CHECK app must have been
started the first time and the connecting process must bave been performed
successfully and the app displays the image for “Step 15” (See Page 30) .
For performing a measurement, one of the modes displayed on the start page
of the app must be selected (Figure 5). With the mode CAROTENOID, you can
only measure carotenoids. It is a marker of antioxidants concentration in skin
and blood. The HEART mode enables the measurement of Heart Rate Variability
(HRV); Heart Rate (Fitness); the calculation of Biological Age; and Body Mass
Index (BMI). If you select the mode VITALITY, your results will be a combination
of both heart and carotenoid mode. Your measurement will test for carotenoids,
HRV, HR, Biological Age and BMI. The results are plotted in the Vitality Report
together and displayed in the web browser of your phone/tablet.
9.2: Measurement Modes

KHACHIK CHECKER MANUAL

9 STEPS FOR PERFORMING A MEASUREMENT9 STEPS FOR PERFORMING A MEASUREMENT
33 34
The mode CAROTENOID offers two different methods for measuring carotenoid
concentration: FULL and LIGHT (
see next page ).
The FULL measurement is what you typically use. It will measure your nutrition
with a precision which is good enough to make changes in your nutrition visible
after just a few weeks of a changed diet. In this mode, you must perform 4
measurements in succession. This greatly reduces the chance of measurement
errors, as measurements where improper or unideal positioning between the
skin and the scanner can be eliminated. It also means that you must perform the
same process four times before getting the final result.
The data of each of these four results are evaluated directly after each
measurement taken. As a result, you may begin seeing recommendation
messages if you have not placed the hand on the sensor properly. Therefore,
user experience can be improved within the measurement process.
The LIGHT version can be used for a quick check when you do not have enough
time to perform a FULL measurement. It is not recommended for new users,
because it cannot detect if your hand did not make contact with the sensor
correctly during the measurement. Before using the LIGHT mode, please also
consider using FULL mode without “ WIFI query ”, which offers you the precision of
the FULL mode within less time than the FULL mode.
After you have selected CAROTENOIDS, HEART, or VITALITY please continue
to follow the instructions shown on the app and place your hand on the sensor
accordingly.
Do not move your hand and do not lift it before the app is asking to do it.

9 STEPS FOR PERFORMING A MEASUREMENT
After selecting the FULL or LIGHT measurement mode, the app will attempt to
connect to your scanner and phone/tablet via the WIFI connection synced with
your devices ( Figure 6 ).
When scanner and phone/tablet are connected, the app requests you to place
the ball of the thumb on the sensor by aligning the hand with the line of the
sensor precisely. The scanner will now check if your hand is present. Every time
the scanner checks for your hand it will flash with orange LEDs. The measurement
will only start if the hand is placed on the sensor.
Figure 6
9 STEPS FOR PERFORMING A MEASUREMENT
An automatic timeout will stop the orange blinking after 60 seconds if the user has
not placed their hand on the sensor. If the sensor has detected the placement of
the hand, the measurement starts. The smallest symbol of the progress indicator
will stop blinking, and the lights will be a permanent green. At that time, the
hand should not be moved on the sensor to avoid a miss reading. The progress
indicator LEDs on the scanner shows the progress. A green bar on the app
indicates the progress too (Figure 7) .
When the measurement is in progress, the second symbol of the progress
indicator will light up after some time. The green bar in the app displays the
progress of how much of the measurement data has arrived at the phone/
tablet. The WIFI indicator flashes once for every packet of data transferred. The
measurement is finished when all three symbols of the progress indicator are
green and the app requests you to take off your hand from sensor.

9 STEPS FOR PERFORMING A MEASUREMENT
If you do not remove your hand from the sensor, the data will not be sent to
the server. When taking your hand off, the app will attempt to connect to the
internet. Therefore, the phone/tablet disconnects from the scanner and the WIFI
indicator turns off. Only the status indicator still lights up in blue (Figure 8) .
Your phone/tablet will connect to an existing WIFI or alternatively use a cellular
connection to the internet. After successful connection, the app informs you that
the data has been sent to the server. When the result is available the result is
sent to the KHACHIK CHECK website to display it (
Figure 9 ).
