1 How to get started
Please read the chapters of this manual in the ranked order carefully to correctly learn the handling of the device.
Before you can proceed a measurement, you must download the VITALITY CHECK app on your phone or tablet (chapter 5) and you must charge the battery of your device (chapter 8). With a low charging level, it is impossible to switch on the device successfully.
The chapter 9 describes all steps you need to get a measurement done. When the device is switched on the light of the indicators informs you always about the present status. If the indication is not identical with the descriptions in chapter 9, you did not pass the present step correctly. In that case please go to the chapter 11 (“Troubleshooting”) and read the information for the related indication. For every indication, a method is described how to leave this status and how to go on with the measurement. Since the lights of the indicators have an automatically timeout, please memorize the configuration of lighting before searching in the chapter 11.

9 Steps for Performing a measurement
To perform a measurement with the VITALITY CHECK successfully please follow the steps below in the described ranking.
Performing a measurement and charging of the battery at the same time is not possible, because charging can influence the quality of the measurement. Please remove the USB cable before starting a measurement.
9.1 Turning the device ON and OFF
At the time the VITALITY CHECK is switched off, no LED is shining. If a LED is shining please switch at first the device off by a long press (ca. 15 sec.) on the ON/OFF button.
When you switch on the device by pressing the ON/OFF button the status indicator should light blue. If not please press the connectivity button until the status indicator lights blue. Blue indicates that the scanner has open an WiFi access point (Figure 4). For connecting the device with the WiFi access point please see chapter 9.2.
If there is no further action by a timeout of 60 seconds the device will switched off automatically.
When switching the scanner on by pressing the power button while charging the battery or when the battery has been charged before and the scanner is still connected with USB cable the status indicator will be lighting white (Figure 5) and will not open a WiFi access point. Please disconnect the USB cable.
If the battery level of the device is too low to conduct a measurement, the status indicator will be blinking several times in red before the device is switched off automatically. If the device does not switch on, the batter may be completely empty. In both cases please charge the battery (chapter 8).
9.2 How to Connect with the Access Point/WiFi of the Scanner
After you have switched on the device successfully, the status indicator lights blue. If not press the connectivity button until the indicator lights blue. Blue indicates that the scanner has open an WiFi access point. In the access point mode, the scanner provides WiFi a smartphone can connect to.
Switch now your phone/tablet on, open the Vitality app and select the “Setup wizard” by pressing the three-bar sign on top of the left corner (Figure 7). Please follow step by step the procedure of the “Setup wizard” for connecting scanner and phone/tablet (chapter 9.3 and 9.4) and subsequent for connecting the scanner with the external WiFi or with the hotspot of a phone/tablet (chapter 9.5).
To enable a connection between scanner and phone/tablet the wizard requests you to open the settings of your phone/tablet and the selection of the WiFi settings. All WiFi networks around will be displayed. Please select biozoom_xxxx (Figure 7) it is the WiFi name of the access point of your scanner. Instead of the “xxxx” a four-digit number is displayed consisting of numbers (0-9) and/or letters (a-f). On the back side of the scanner the specific WiFi name of your scanner is printed. Some phones/tablets inform you that the selected WiFi has no internet connection. This is correct because the access point connects only scanner and phone/tablet. In some cases, the Phone/tablet requests you to confirm that an internet connection does not exist. Please confirm it. If you do not confirm scanner and phone/tablet will be connected.
9.3 Confirmation of a Connection to the Access Point
The smallest symbol of the progress indicator (6) lights in green, if the scanner is connected with a phone.
9.4 Confirmation of a Connection between App and Scanner
The first and the second symbol of the progress indicator light green and the status indicator lights blue if the scanner is connected with the VITALITY CHECK app on your phone/tablet.
9.5 Selection of the WiFi for Proceeding Measurements
When proceeding a measurement, the measured data will be sent to a central server for calculation. The result will be displayed on the phone/tablet. Therefore, the scanner must be connected with a WiFi network that transfer the data via internet to the central server. There are two possibilities to do it:
Applying an existing WiFi e.g. your WiFi at home or the office WiFi
Applying the hotspot of the phone/tablet
If you have not established a hotspot on your phone so far you must do a related configuration first because name and password of the hotspot must be known for the connection of scanner and hotspot. Open the settings of your phone. In most cases the hotspot is a submenu of the WiFi settings. Use for the configuration of the hotspot a name and a password you remember well; it helps you when connecting the scanner with the hotspot.
The following existing WiFi´s cannot be used:
WiFi networks where you need to enter information in a browser to get access, e.g. hotel WiFi´s, WiFi in some trains or airplanes
WiFi networks which do not allow communication from one device to another, e.g. hotel WiFi´s, company guest networks
In all this cases please select alternatively the hotspot of your phone/tablet
9.5.1 Applying an Existing WiFi
The scanner is scanning for WiFi networks continuously and send the detected networks via access point to the phone/tablet (see chapter 9.4). The networks are displayed in the VITALITY CHECK app. Please select the WiFi network of your preference and insert the password into window opened. If the scanner can connect to the specified WiFi network, all three symbols of the progress indicator lights green. The status indicator lights blue.
If the scanner is connected with the WiFi network the access point will be closed. Therefore, the WiFi indicator and the status indicator lights green and the light of the progress indicator is switched off.
To enable furthermore the communication between scanner and phone/tablet the phone/tablet must now also be connected with that same WiFi the scanner is connected. If this WiFi is your home WiFi or your office WiFi then mostly your phone was already connected with that WiFi before. In this case your phone/tablet connects with this WiFi automatically and no further action for connecting scanner and phone/tablet is necessary.
In all other cases you must now open the settings of your phone/tablet. Please select the submenu for the WiFi settings. Connect your phone to the same WiFi Network your scanner is connected.
Scanner and phone/tablet are communicating now via the router (existing WiFi network).
The VITALITY CHECK will now be ready for measurement. The app is displaying the page for starting a measurement.
9.5.2 Applying Hotspot of the Phone/Tablet
You have followed the instructions of chapter 9.2 – 9.5 successfully. Therefore, the status indicator lights blue and two symbols of the progress indicator light green indicating that the scanner and the app are connected via the access point of the scanner. The scanner is now scanning for WiFi networks continuously the detected networks are displayed in the app.
To connect now the scanner with the hotspot of the phone/tablet you must press the plus sign (+) on top of the screen. Into the window that will be opened you can enter SSID (name of the hotspot) and the password of the hotspot. Press the word “connect” to finish the procedure.
The information will be sent to the scanner via the existing access point connection. Of course, the attempt to connect the scanner with the hotspot must fail because the hotspot has not been opened yet.
Therefore, please open now the WiFi settings of the smartphone and switch the hotspot on (Figure 13a). In consequence the access point connection will be stopped. Since the scanner has stored the transmitted credentials all signs of the progress indicator are switched on to confirm that the hotspot is open now.
Please switch now the scanner off and switch it on again. The scanner will be automatically connected with the hotspot. To indicate this the status indicator and the WiFi indicator will light green and the light of the progress indicator is switched off.
The VITALITY CHECK app is displaying the page for starting a measurement (Figure 14). By pressing the apple sign you can start a measurement.
9.5.3 Automatically Connection with a WiFi Network
The scanner will store the credentials of the last connected WiFi network. Therefore, an automatically connection with this network will happened in the next session if this network is available. This is very comfortable because you can skip some of the steps described before. Please note, that only the last used network is stored. Nevertheless, there are small differences in the procedure when connecting with an existing WiFi network or a hotspot.
Connection with an existing WiFi Network
For an automatically connection please proceed as follow:
Switch your phone/tablet on
Since your phone/tablet will store the credentials of the WiFi networks you have been connected before the connection will directly be established after you have switched it on. Of course, if your phone/tablet was already switched on the connection will be established if the router is visible for your phone/tablet.
Note: If you have several routers or WiFi access points, you need to connect your phone to the same WiFi your scanner is configured to connect to.
Open the VITALITY CHECK app
Switch the scanner on
The status indicator will light orange very short but change immediately to green. The WiFi indicator lights green too. Since the scanner is now connected with the existing WiFi it is ready to proceed a measurement.
Connection with the hotspot
For an automatically connection please proceed as follow:
Switch your phone/tablet on.
Please open now the WiFi settings of your phone/tablet. You will find a submenu for opening a WiFi hotspot. Please activate the hotspot.
Switch the scanner on
The status indicator will light orange very short but change immediately to green. The WiFi indicator lights green too. Since the scanner is now connected with the hotspot it is ready to proceed a measurement.
9.6 Performing a Measurement
Before you measure the first time please read the general recommendations for a correct measurement listed in chapter 10 “Measurement Basics”. It helps you much to receive a correct result.
9.6.1 Automatically Hand Recognition
You have opened the VITALITY CHECK app and see the button “Start measurement” (status indicator and WiFi indicator lights). Please press now the button. The smallest symbol of the progress indicator will blink green to request you to place your hand onto the sensor.
Note: Please carefully read the instructions on how to position your hand on the sensor to obtain a correct measurement (see chapter 10).
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. This is a safety mechanism to prevent that the user do suffer from the bright light of a running measurement. An automatically timeout will stop the orange blinking after 60 seconds if the user has not placed his hand on the sensor.
9.6.2 Automatically Start of the Measurement
If the sensor has detected the placement of the hand the measurement starts, and the smallest symbol of the progress indicator stops blinking and lights permanently in green. At that time, the hand should not be moved on the sensor to avoid a miss reading. The small symbol indicates that the measurement is in the first half.
The measured data are continuously transferred via WiFi and internet to server for calculation. Any time a package of data is sent the WiFi indicator will flickering.
9.6.3 Progress of the Measurement
Since the measurement is in progress the first and the second symbol of the progress indicator will light after some time.
The measurement is finish when all three symbols of the progress indicator lights green. The hand should now be removed from the sensor.
If you don’t remove your hand the smallest symbol of the progress indicator will start blinking. Please remove your hand now.
If you have removed your hand the first two symbols of the progress indicator are switched off directly. The third symbol will light until all data has been transferred to the server.
When all data has been sent to the server also the biggest symbol of the progress indicator will be switched off and only status indicator and WiFi indicator keeps light.
When you perform an antioxidant intensive measurement the next measurement must be performed. Therefore, the smallest symbol of the progress indicator is blinking again, and four LEDs of the sensor are continuously switched on one after the other. It indicates that you must place your hand on the sensor area again. Please follow the procedure descript in previous chapters (9.6.1 ff). If you do not place your hand an error message will be displayed on the phone/tablet after 60 seconds.
If you have performed all four measurements of the intensive measurement procedure or you have done only a single measurement the scanner will be switched off automatically. The app informs you simultaneously that the result is available. When pressing the displayed link, a website will open presenting the result as well as recommendations for improving this result.
If you like to conduct an additional measurement you must open the app and must switch on the scanner again.
10 Measurement basics
The VITALITY CHECK is a sensitive sensor that is able to detect certain substances in the human skin. It is helpful to follow the tips below to get precise and reliable results.
Preparation before starting measurement
Rest your body before starting measurement.
If you do physical exercise right before the measurement, you can often see an effect on your antioxidant measurement as well as on heart rate variability that does not reflect your general level. If you want the maximum measurement precision, allow your body to rest 20 minutes between exercise and measurement.
Measure at the same time each day to get consistent results. The antioxidant level may change during the day.
During sleep your body relaxes and recovers. You can see that in the antioxidant value as well. Most people have a higher value in the morning and during the activity and stress of the day the value drops and is lowest in the evening. With some people, it goes up right after they had healthy food and a lunchbreak. The changes between morning and evening typically have a magnitude of 0.1 to 0.5. You can also find differences between Monday and Friday because of workload or job-related stress and the recovering at the weekend.
Measure with dry skin only. If you washed your hands with soap and dried them up thoroughly, there is still some water that remains on the skin for a while. It will have a small effect on the measurement, so it is better to wait 30 minutes after washing hands to get the most precise results.
Measure on unhurt, healthy, untreated, bare, and dry skin only to get consistent results. If you suffer from any skin diseases, the sensor will probably not be able to measure correctly, because it is calibrated for healthy skin only.
Skin treatments of any kind, e.g., skin care products, cosmetics, sun protection, tattoos, will influence the measurement. Hair will also have an influence. Therefore, we recommend measuring on the base of your right hand’s thumb.
Measure in sitting position with the scanner lying on the table.
Rest your elbow on the table for controlling the pressure when placing the hand on the sensor. Apply no additional force, the weight of your hand/arm is enough
You can get to the ideal contact pressure by letting the hand rest on the sensor with its own weight. Do not use the muscles of the arm to lift the hand or to press it onto the sensor. The ideal contact pressure is approximately equivalent to 800g of weight which is about two pounds. The reason for this is, that your blood contains antioxidants. If you press against the sensor too hard, you push some blood out of the skin and change the effective antioxidant level. The sensor has a function that compensates the effect of the contact force. So, you do not need to worry to get a perfect contact pressure. But if your contact pressure is ideal you still get a little bit better result. Pushing blood out of the skin will make the measurement of heart rate variability complete impossible.
Seating position - sensor on the table. Rest the elbow on the table - no additional force when measuring
Lay your right hand softly on the sensor by using the groove to align the hand precisely. Measuring always the exact same spot helps you to see the effect of a change in nutrition and lifestyle correctly.
Do not move your hand or shift weight during measurement.
It is important to hold your hand still during the measurement. The sensor does a set of different measurements and compares the results. If the hand moves between the measurements or the contact to the sensor varies the comparison works less well.
Avoid bright light on your hand while measuring (sunlight, bright artificial light). Cover the hand if necessary.
Bright light can get through your hand. You can try that by switching on the LED flashlight of your smartphone and putting a finger on top of it. You can see that especially red light can get all the way through your finger. Sunlight is even stronger and can get through all your hand. That is why the biozoom sensor does refuse to measure in direct sunlight. If you want the maximum precision, you can help the sensor by making sure no bright light hits the back of your hand while measuring. Normal ceiling light is mostly no problem.
General aspects influencing the level of measured results
Note that prolonged exposure to sunlight or the use of sunbed may temporarily lower your antioxidant value.
Influence of wearing gloves
If you wear gloves at work, be aware that there sometimes is a significant effect on the antioxidant concentration. You will get better results if you always measure before work.
Note that illness may lower your antioxidant value.
If you have a cold or some other illness it means stress for your body. Be aware that usually your antioxidant values go down in such a case. Wait until you have recovered before you compare two results.
Reasonable physical exercise supports your antioxidant level, but strong physical exercise may temporarily lower your antioxidant value.
Note that smoking result in a constant lower level of antioxidant value compared to non-smoking
Note that excessive consumption of alcohol may lower the antioxidant value temporarily
Below you find a table summarizing all functions and indication relevant for the use of the scanner. If you meet an unexpected behavior of the scanner this table helps you to understand it fast. If further actions are necessary, this table inform about this.
