Have a great day everyone. My new sensor and Glimp had a spat last night. MM alarms went three times with rubbish data of 0.8 jumps and troughs. Enough was enough. I am now, finally, on X-Drip. And you calibrate it. So that a million times better already. I know I should have got Xdrip eons ago Knikki
, but it's sometimes easier to stay with the devil you know. But the devil last night was too much.
Ert, I made quite a few mistakes in my first week or two with xDrip+. I was constantly feeding in calibrations every time it was out, thinking that would make it better but it was making it worse.
You should calibrate when you think your ifg is similar to bg. Early morning when you've been running stable overnight is a good time. Look for a straightish line for about an hour or so. If it's trending up or down, do not calibrate then.
That way, if the reader is telling you some guff like bg is 2.8 whereas the meter is telling you it's 4.2 and it looks from the line like you've been stable, feed the 4.2 in as a calibration so that xDrip+ knows that the raw number it is getting means 4.2 and not 2.8.
Whereas if you've just had a meal and bg has risen to, say, 7, but the glucose hasn't yet seeped out into the interstitial fluid, so, say, interstitial fluid is still at 5, feeding 7 in in a situation where the if is actually still 5 is just going to confuse the heck out of it - it will interpret further 5 ifg as 7 when it's not.
William Lee Dubois' Beyond Fingersticks... discusses this in more detail.
Also, when you change sensors, you don't want cals from the last sensor screwing things up, as each sensor has a different "personality", so go into the main menu, top left, select Stop Sensor, then Don't Stop Sensor, Just Reset All Calibrations.
It'll then ask you to type in two bg readings, you don't need to test twice, typing in one reading twice will do.
My reader this morning was saying 2.8. Bg said 4.6. xDrip+ was saying 4.3. That's good enough for me!
Have fun with it - get it calibrated properly, it's an incredibly useful app.
