Important notice to all TICKOPRINT users and testers:
We have recently encountered that operating TICKOPRINT with the power supply attached to the Android device for charging affects the accuracy of beat count detection as well as the entire accuracy of tests performed by TICKOPRINT.
This is a result of poor noise frequencies reduction inside the power supply and no TICKOPRINT fault. To avoid future misreadings of TICKOPRINT we have included a warning message when a test is started while the device is being charged. This enhancement is being distributed with the next update of TICKOPRINT.
This is a very severe error caused by poor circuit quality of the majority of provided power supplies, and may have lead into difficulties using TICKOPRINT as being reported by a numbers of users.
