This is NOT the Expert, it's the Combo. It does everything in 0.1 of a unit. The bolus wizard for the Combo pump IS the meter! No need to ever touch the pump until you get undressed at night.
Nat - if you didn't deliver the insulin it said, you should be able to amend it using the meter. If you delivered the insulin then it doesn't let you.
My Data, then View Data. Scroll down to the one where you didn't deliver the insulin, click the middle button,, two choices Back and Modify, choose Modify, scroll down to carbs and change to 0, then 'Save'.
I know that, because I've just done it to make sure it works and am thoroughly enjoying the coconut macaroon (19g LOL) thank you! - I wouldn't have had it were it not for you!

Very nice indeed.
So I did a normal test, carbs, bolus, worked it out, 1.7u - then turned the meter off. Made coffee, got cake, came back in, retested and told it the carbs and asked it for the bolus again, 1.7u, yes please, deliver it. Turned meter off then back on and when I got to View Date, the apple and the insulin were showing at the latest one, but just the apple for the first one. So I chose that and changed the carbs to Nil.
You do not have to retest when that happens you know, you can tell it NO. Remember it's still getting the info from your pump so if your pump hasn't recorded a bolus, then the meter knows you haven't had one and there's an end to that. If you don't change it and leave it as it is, it will show up when you download em to the software, comes up in red or with some sort of sign by it to show it's a query. Meter data does not match pump data or something.
These poor pumpless people who use the Expert with MDI are missing out, aren't they? Shame LOL
As since I've had the twins (LOL) I haven't ever delivered any insulin my injection, there is a way of recording that you have (and when you download it, it has a little syringe by it, quite sweet!) but I dunno how you actually tell it that. I tend to not concern myself about subtle nuances like that until I have a real one to practice on LOL, then you can make sense whereas if it's all in theory and you are only playing, it might not behave the same as if it was real.
