[QUOTE="LittleGreyCat, post: 2084441, member: 6467"] I'm also having fun times trying to calibrate the sensor against my finger prick tester. Basic test is to take a finger prick and scan the sensor, put a timer on for 10 minutes, then scan the sensor. Finger prick again, timer on, 10 minutes later scan the sensor then finger prick again. This in theory should give a matching set up numbers with an offset (10 minutes is first guess). At the first test the numbers aligned, 8.3/8.4 but now the sensor is showing a regular drop and is down in the high 6s whilst my finger prick is showing a steady 8.3/8.4. It does look as though the sensor is reading a lot lower than my finger prick at the moment but I'm trying to work out why the sensor is showing a steep drop in BG when the finger prick is showing a steady state. If I understand it correctly the finger prick should be ahead of the interstitial fluid and the sensor, so that the finger prick is more immediate and the sensor data trails behind it. At the moment my first impression is that the sensor is ahead of the finger prick, as it shows a steep drop in BG while the finger prick was steady, but is now dropping. I think I need to wait until the sensor reading stabilises - that is, roughly a flat line, before I can estimate how far apart the finger prick is from the sensor. I can't at the moment see any way to read individual values from the sensor using the phone App or the web site - I just see a graph line with very poor granularity. Edit: just found the Logbook option shows the individual readings. Phew! [/QUOTE]
