I think when you get the cable you can use diasend instead of the 360 software. I haven't done myself so I'm not 100% sure on that.

Interesting that it is infra red. I thought it was Bluetooth from the little I read last night. My pump uses infra red and it is slow and picky about placement.
AFAIK there is no such cable available from Roche.  I've used the Libre reader to upload to diasend, but unless you have the specialist machine the clinics have, I don't think you can upload the Roche meters to Diasend yourself.

Ah thanks, I had been in the logged in part of site where you order batteries etc and couldn’t find anything, I’ve sent an email to customer services. Shame about them making it difficult to get the data, I do like diasend. At least you can do basic views of averages etc on the meter.

Today for lunch I didn’t really understand how it had worked it out.

Carbs 50. 6.3u
Bg 7.9. Target is 4-8 and 1u drops 2. It gave 0.1 correction.

Guessing maybe that wasn’t a correction as such and was just to round my dose up to 6.5 total? I’d normally take 1u if I was 7.9 before lunch, to get to about 6 before dinner.

Did you still have IOB (insulin on board) from breakfast maybe? Like it expected the insulin from breakfast to cover the high?

It depends what you have set as duration of bolus insulin.  As Liam says, if the meter thought that your breakfast bolus still had some life in it, it would deduct that from the correction dose.  Say you'd set your bolus duration as 4.5 hours and you'd injected at 8.30 am and had lunch at 12 noon you'd still have 1 hour of active bolus.  So the meter does a calculation to factor that in and deducts it from the correction element of your lunchtime bolus.

That's why these meters (and pump handsets) are so good, because they do the bits of calculation that it would be really hard for us to do.  I mean we can all work out X carbs to Y units, we just can't really factor in active boluses etc with any degree of accuracy.

I’ve asked around and found a couple of explanations for this. It seems that there is a carb duration setting in the meter, and I’d entered a snack earlier in the morning (just for future reference in case I wondered about my prelunch bg) but hadn’t taken any insulin for it. Apparently the meter doesn’t correct for the part of bg it thinks is due to the rise from the carbs you’ve eaten, which may be why it’s not been giving a correction on those occasions.

I also wonder if when you are within the target range it rounds the insulin dose towards the midpoint but doesn’t really add a correction as such. Not sure on that but seems to be what happens, I’ve changed the target range from 4-8 to 5-7, in case this is the case, as I have a half unit pen and use 1u drops 2.

Next difficulty is getting my strips changed. The dsn gave me 40 initially last Tuesday but I’ve run out of these now and haven’t got them on my repeat prescription list yet, though my old ones have been removed. So I’ve been to the GPS today to chase these and was told it’s waiting for change in prescription to be approved by a dr, so someone is going to ask my GP if he can do these since I’ve run out. I’ve got some old strips so I’ll stick to those for now. (If anyone needs a spare contour next one meter I’ve got 3 plus a few strips!). Next battle will be getting enough strips, as usually whenever I change brand they get put back to 50 instead of 200...

I also rang accu chek to ask about the software, they’re sending me a cable and a software disc (not sure why this isn’t online download...). Understand previous comments that it isn’t very easy to use or interpret but figured it was worth a look anyway given it’s free.

I have to say that I've never heard of a carb duration and I've had a good look around my old Expert and can't see it at all.  However that's not to say there isn't one, but not all carbs are equal as we know.  Some are absorbed quicker than others and if you have fat and carbs together in your snack wouldn't that slow the carb duration down?

  Yes it does target the midpoint.
Grrr... the old strips issue... good luck!
I'd be interested to know what you think of the software when you get it.

Maybe, rather than an actual 'carbs duration' setting (which I've certainly never come across in either the Expert/Combo handset set-up nor the Insight one - it is part of the Roche algorithm used for their smart meters?

Sorry I remembered the wrong thing, i think it’s called “meal rise” not carb duration. Its in settings, bolus advice, advice options, meal rise, it’s set to 2.8mmol on mine. The “advanced owners booklet” says this about it:

Meal Rise
• During or after meals, an increase in blood glucose levels is considered normal, or “allowed,” within a
certain range, even though a meal bolus has been delivered. A meal rise is in effect for a specified time
period.
• Enter the maximum increase in your blood glucose test result that is to be tolerated without an additional
correction bolus.

Underneath there is a snack size option which is set to 0 on mine. The book says this:
Snack Size
• The snack size is the amount of carbohydrates that is not to be counted as a regular meal with the expected
meal rise.

So I think the combination of those means when I’ve logged anything over 0 carbs it will allow up to 2.8mmol increase before correcting at tests afterwards? Though not sure what it’s comparing the increase to actually. Trying to understand how it’s doing corrections is a bit confusing to be honest.

Ah meal rise and snack size... yes, familiar with both those.  TBH I never eat a snack without a bolus, unless it's a hypo treatment i.e. some Jelly beans or something if I don't have Dextrose to hand, or just fancy a change.  Which means I don't eat snacks generally because I can't be bothered to bolus.  There are exceptions such as when someone insists I have a bit of their cake.
Incidentally when did snack become a verb?  I notice lots of people using the word as a verb these days.
