With the JBL PROSCAN the test results are not affected by the inherent colouration of the water and are still reliable. With the JBL PROAQUATEST drop reagents this effect is compensated by the use of the comparator block and also leads to a reliable test result.
None, is the short answer. As soon as you log into the JBL PROSCAN app on the new smartphone, the measurements saved there are downloaded from your myJBL and are directly available on your new or additional device. Users who have worked without registering cannot save any measurements, and thus cannot lose any.
On the empty JBL PROSCAN COLORCARD you will find grey fields as placeholders indicating how the test strip should be placed. The notes Top and Bottom serve as additional orientation. Since app version 4.0, the app catches alignment errors. After the JBL PROSCAN test strip has been placed, no grey from the placeholder should be visible on any of the fields. It must be completely covered with the colour fields on the test strip. _x000D_ Behind this is the method of colour detection. The sum of all colours on a field is included in the colour detection. Therefore, the grey must be completely covered. Otherwise, erroneous results will occur. _x000D_ _x000D_ Example: A white field is darkened by the grey field template and produces a different result. Excess water and associated reflections can cause a similar effect. Each field must be damp/dry with no water stains or wet patches. You can avoid this by correct handling with sideways tapping (do not shake) and a sheet of kitchen roll as an underlay (reflections!). If you receive an error message during the measuring process, it is probably because the test strip is lying crooked on the JBL PROSCAN COLORCARD, so that the grey is clearly visible. _x000D_
Please make sure that the ProScan analysis strip is correctly aligned. This means that the measurement fields are placed at the word “Top” on the ColorCard. “Bottom” indicates that side of the analysis strip, which you are holding in your hand. _x000D_ When reading the ColorCard the whole card should always be visible in the recording window. A slight margin all around will ensure that the “corner points” can be focused._x000D_
You can store the measured values as an image with the button „Share” or you can send them to yourself by SMS or email. If you are already registered and logged in, the app also gives you the opportunity to display the analysis of the last measurement. All you have to do is click on "Save" on the results page.
The CO2 content, which is only calculated from the values of pH and KH measured, is not displayed in the water type “pond”. This is because there are no systems in place in the pond which can increase or influence the CO2 content. In addition, the large water surface of most ponds ensures there is always sufficient CO2 entering the water from the atmosphere. In addition, most of the plants usually have direct access to the air in the atmosphere.
Each test has a fixed scale, which enables the allocation of the water values. For example the steps in a drop test are different to those of the ProScan. Therefore ProScan also has a scale to enter the values and to avoid jumps at repeated measurements. Bigger differences between the values mostly indicate an incorrect reading caused by shades/reflections. Best is to carry out the test near a window with bright light. Direct light from above casts shadows or reflections which can affect the colour rendering. Please remember ALWAYS to shake the water off the analysis strip sideways. “Puddles” can cause the colour fields to react with each other and to produce reflections._x000D_ Incorrect values can occur through expired drop tests too (i.e. tests which have been open for more than 9 months) or incorrect use (with air-filled drops and deviating water quantities). In this case please check your measurements once more. _x000D_ _x000D_ One example: _x000D_ The aquarium has the following water values: 18 mg/l NO3, 0.5 mg/l NO2, 5° dGH, 7 mg/l CO2, 1.5° dKH, 6.8 pH. _x000D_ _x000D_ The measurements with the different systems give the following values: _x000D_ The ProScan shows following values: 18 mg/l NO3, 0.5 mg/l NO2, > 4° dGH, < 15 mg/l CO2 (by way of calculation), 1.5° dKH, 6.8 pH. _x000D_ The drop test shows the following values: 20 mg/l NO3, 0.6 mg/l NO2, 5° dGH, 10 mg/l CO2 (by way of calculation), 2°dKH, 6.8 pH_x000D_ _x000D_ Both results are very precise and differ only slightly from each other. This has no negative effect on further statements and actions. Inaccuracies in the application have a greater effect on the results than jumps resulting from the scale. Finer scaling steps could result in an inability to allocate the results exactly to the same measuring points when there is some divergence of light and distance in the surroundings. This would cause the values to jump again in a repeated test.
On the ColorCard the "top" and "bottom" are indicated. When picking up the test strips you automatically hold the "bottom" side. It’s the side with no analysis fields on the strip. On the "top" side the analysis fields are printed right to the edge. An error message appearing in the app usually means the analysis strip has been positioned on the ColorCard the wrong way round. Just correct the position.
JBL ProScan is being developed continuously. We will add new functions and features to the app at regular intervals to make water analysis even easier. Always upload the latest version from the Store.
Please note that the analysis strips will continue to react. Thus a strip can only be scanned once. A repeated scan would lead to different values, because they change dramatically after 70+ seconds. However the fluctuations can also indicate an incorrect reading caused by shadows/reflections. It is best to carry out the test near a window with bright light and using a sheet of white paper as a matt non-reflecting base. Direct light from above casts shadows or reflections which can affect the colour rendering. The ColorCard should be uniformly illuminated. Please remember to ALWAYS shake the water sideways off the analysis strip. “Puddles” can cause the colour fields to react with each other and to produce reflections. Please always approach your smartphone vertically to the ColorCard.
JBL ProScan Recharge are special digital analysis strips which have been designed for the ProScan app. They enable a detailed and precise evaluation in small scaling steps. JBL undertakes no guarantee for the correctness for the use of the EasyTest 6in1 strips. These have definitely less fine scaling steps and are not suitable for reliable measurement analysis. They are therefore incompatible.
JBL ProScan is not designed for use in saltwater. The scales of measurement and recommendations inside apply only to freshwater.
In order to determine the photometric measuring results accurately ProScan needs a camera with autofocus. This is the only way to determine the results with maximum precision. Not having one could prevent you from downloading the app from the store. Moreover the app requires the Android version 7.0 or higher or iOS 13.0 or higher. It is compatible with iPhone, iPad and iPod touch, as well as with 5100 Android smartphone and tablet types. If the download in the store doesn’t work, your mobile is probably incompatible with one of the above mentioned points. If there are any problems during use, e.g. with the scanning, please contact our customer service team: www.jbl.de/en/support .
JBL ProScan is being developed continuously. We will repair bugs and small errors which can be caused by software updates as soon as we can. To help us in this, we request a short email to socialmedia@jbl.de with the software version, device name, designation of the smartphone and a description of the errors with words and pictures.
In the operating system of your smartphone there is a resource management. This also manages your camera. Because other apps are accessing the camera too, it can occasionally happen after use that a new access is not granted and therefore a blockage can occur. As result you receive an error message from your ProScan app despite a correctly aligned analysis strip. Especially after an update you can find the resource “camera” blocked for further apps, including JBL ProScan. _x000D_ _x000D_ In many cases the solution is quite simple: Close all the apps in the background on your task manager. Now restart your smartphone and open JBL ProScan as your first app. Carry out the scan again. By closing and restarting all the resources will be released. If the error still occurs, the test strip is not correctly aligned on the ColorCard. You can also test the app is working by carrying out a test scan without an analysis strip and using the empty ColorCard.
A loose seal may result in an indication of positive false chlorine values occurring with the following batches of the ProScan Recharge test strip sets: 421141; 44114; 42114; 43114 and 11035. _x000D_ _x000D_ If you have purchased your ProScan within the last 6 months, we will send you a refill pack free of charge. Please remember the test strips can be damaged by humidity through a longer service life and frequent use. A package (24 test strips) should therefore be used within 9 months. Converted into use this means that you should carry out a water test every 1.5 weeks.
If your new measurements cannot be successfully transferred, it is probably because your access data has changed. Each measurement is linked to its user's record on the creation date. If the measurement is not transferred (missing Internet connection) and your access data changes (password changed), this error occurs. Solution: Please delete the app, confirm the removal of the locally saved data and reinstall the app. If you now log in, your profiles will be downloaded and with the first addition of a new, further measurement you will also see your old measurements in the app again. On the JBL website you can view and compare all the measurements you have saved at any time under myJBL --> My analyses.
Please use your username and password to log in to the app. The email address will not be accepted as username. Make sure beforehand that you have already created a myJBL profile.
The data exchange between the ProScan app and your JBL online profile is unidirectional. That means that the communication only works in one direction, namely from the app to your JBL account. All aquariums, ponds and waters and their relevant measurements are saved there under “My Analyses”. _x000D_ That’s why the last 5 measurements are no longer visible on the app after a change of the smartphone or tablet since they are only locally on one device. The measurements from your tablet are not located on your smartphone and vice versa. In the next months we will extend the interface and initiate a bidirectional data reconciliation. Thus the communication between all devices will be possible and the profiles of the waters won’t need to be created several times.
Unlike the other six parameters on the quick test strip of the JBL PROSCAN digital water test, the CO2 content is calculated on the basis of the pH and carbonate hardness values measured in your aquarium water. This is reported in three categories: "Value too low", "Everything OK" and "Value too high". You may recognise this procedure from the so-called CO2 tables which you can also find in the JBL Themeworld Aquarium: _x000D_ _x000D_ https://www.jbl.de/?mod=areas&func=essential_section&lang=en&id=74&country=gb _x000D_ _x000D_ The procedure is only an indicator, however, as other acidic substances can falsify the calculation. If you want to know the exact content, a drop test will help. You can carry out this fast and very accurate method of determining the CO2 content with the JBL PROAQUATEST CO2 Direct. Just add an indicator liquid to a sample of your aquarium water and count the drops until a stable pink coloration is obtained. This test even enables you to eliminate other acid influences on the test result._x000D_ ._x000D_ .
Unfortunately it is not possible to print the ColorCard of ProScan yourself. It is produced by means of a special printing process and afterwards tested on a special device for colour fastness. _x000D_ Only this way can we guarantee the high accuracy of measurements made with the ProScan test kits.
Test strips are sensitive to moisture. The reaction starts immediately on contact. Please only remove the number of test strips you need and immediately reseal the container. The container contains a desiccant to absorb the moisture from any air trapped inside. If the container is left open for some time, a reaction may already have occurred rendering the test strips unusable. The digital test strips for JBL PROSCAN are much more sensitive to the effects of moisture than the somewhat coarser scaled JBL PROAQUATEST EASY 7in1. Always store the test strips in a cool and dry place.
The focusing of the image and thus the measurement of the test strip on the JBL PROSCAN COLORCARD does not start immediately after the 60 seconds have elapsed, and this gives you time to lift the smartphone and position it horizontally to the COLORCARD with the correct image section. If the measurement were to start immediately after the time expiry, the capture would have you lifting the smartphone slanted in front of your body. These distortions cause erroneous readings. Therefore, since app version 4.0, a 3-second delay has been added to help you achieve correct alignment and always capture correctly. _x000D_ _x000D_ By tapping the display with your finger, the focusing can also be restarted manually after the 3 seconds. Repeating the measurement or "back" is prevented at this point, as otherwise incorrect measurement values will be obtained. The measurement must be taken within 10 seconds after the 60 seconds have elapsed. Otherwise the test strip is unusable. If this happens the test needs to be started again from the beginning with a new test strip.
The flash and torch functions are deactivated within the JBL PROSCAN app. Uniform and shadow-free illumination is essential for the precise performance of the test with exact results. Occasional shadows or over-illumination cause faulty measurement results due to the sensitive "eyes" of the smartphone camera, which aligns the colour dots of the JBL PROSCAN COLORCARD. A daylight-bright room or a measurement under the open sky / at the window always ensure the right light. The COLORCARD takes over the interpretation through the lighting mood and different camera types. Artificial light with strong colouration should be avoided.
If you go on our website to view the online profiles under myJBL --> myAnalyses, you will find all the measurements. As soon as you log in again with your smartphone and add a new measurement to the respective profile, the 4 latest measurements will also be downloaded from the cloud and will be available again on your smartphone.
Yes, this is possible without any problems. Please uninstall your current app and download the JBL PROSCAN app again from the AppleStore. For all users from version 13.0 onwards, only the new JBL PROSCAN version 4.X is offered. For users of older versions, version 3.X is still available for download. Maintenance and servicing of this version is no longer carried out. The use of the camera requires the current version to ensure the most accurate results._x000D_
