Thank you LucySW and tims2000 Much clearer
It has two sorts of readings: when you scan, but also every 15 mins of its own accord. (This 'historic' reading is actually made up of the average of lots of micro measurements, which means it's more reliable than the scan measurements. I use the historic readings for my calculations, not the scans.)
So just to be clear, even if you only scan once every 8 hrs to transfer the data from the sensor to the reader, all the data will sit and stay on your reader for a matter of months. So when you plug the reader into your PC and export the data, all the historic data - all the every-15-minute numbers - will be there.
That's what I find the most useful. I don't scan that often unless something is up. I look at the numbers later, after a specific meal or un-clever mistake I made.
So yes, you can do a basal test any, any time, just by skipping a meal for the five-hour period. It's WONDERFUL !!
It's Near Field Communication (NFC) rather than bluetooth, so it can't transmit more than about 4 inches/10 cmSo what is stopping the device from scanning say every hour without any manual scan.....?
You have to press a button on the device to take a scan, it then captures the last 8 hours data from the sensor and stores it on the reader, so you can see the current reading and a graph of your levels for the last 8 hours (and all the history for the last 2-3 months). It's very rare that I sleep for more than 8 hours, so scanning is really not a problem. You can't calibrate the Libre as it's factory calibrated.thanks robert....
just wondering why we need to scan at all if its capable of taking readings.....
is this in order to calibrate if needed....
Im just trying to ascertain whether the last 8 hours of data, a nice graph in this case, is just the device joining the dots if you like, between one physical scan to the next....
