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).

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.
