Elevated levels of chlorine due to damp
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.
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.
Why am I getting the message „measurement not possible“
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.
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.
How do I report a new error?
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 firstname.lastname@example.org with the software version, device name, designation of the smartphone and a description of the errors with words and pictures.
How can I store the measurement values?
You can store the measured values as an image with the button „Share” or you can send them to yourself by SMS or email. In addition the app gives you the opportunity to display the analysis of the last measurement. Just click on “Back” and confirm with “Yes” when prompted to save.
Can I also use it in saltwater?
JBL ProScan is not designed for use in saltwater. The scales of measurement and recommendations inside apply only to freshwater.
Why doesn’t ProScape work on my mobile?
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 4.0 or higher or iOS 5.0 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 us at www.jbl.de/en/support .
Will the ProScan app have any new features in the future?
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.
Why do I get different measurement results with repeated measurements?
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.
Can I also use the EasyTest strips?
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.
Which way round do I place the ProScan analysis strip onto the ColorCard?
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.
Why don’t the water values match my JBL drop count test?
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.
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.
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.
The measurements with the different systems give the following values:
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.
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
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.
