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.
If you go on our website to view the profiles online under myJBL --> myAnalyses, you will find all the measurements here. As soon as you log yourself in again with your smartphone and add a new measurement to the relevant profile, the 4 latest measurements will also be downloaded from the cloud and will be available again on the smartphone.
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.
Only this way can we guarantee the high accuracy of measurements made with the ProScan test kits.
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.

Many aquarium owners think that the general hardness represents the total of all minerals and the carbonate hardness only a part of it. Then how can the carbonate hardness sometimes be higher than the total of minerals?Find out more
Our 15 expeditions have taught us something new: In natural waters nitrogens (ammonium/ammonia, nitrite and nitrate) and phosphates are ALWAYS scarce and below the limit of detection. Only when humans have an influence on the natural water, can nitrogens and phosphates be found.Find out more
