And what is this event registration?

Hello.
Well I know what literally means that "event record" in freestyle but where can I "decipher" the keys? How is it in the attachment, the last event gave me yesterday at 00:31 hours, it is aEr3,373, P and for my check it is the typical reading failure that tells you that you do it again within 10 minutes. Some other I think it is because the sensor loses the connection with the reader, but I would like Seber if there isAlgù equivalent in some place that interpreted them. I have looked in the instructions for use but find nothing.
Thanks and greetings.

It is the log of failures, each code means something for the manufacturer.
I believe that the ER0,987 are connection losses, but they are not relevant because the sensor stores the data of the last 8 hours.

Thanks, I already have it clearer.
