15 min delay
Ive always left mine on 24 hrs min before activating

In my experience, I have found around 36 hours to be a good time to activate, but I make sure this coincides with my first overnight. The first few hours can be hit and miss with me, no matter how long I leave the activation, so when I am asleep for the first time I am not really bothered. By morning it has righted itself. (won't be the same answer from insulin users)

As for time lag, it seems to vary between person to person, and also in the same person. I tend to leave between 10 and 15 minutes between a test and a scan. However, when I download my 15 minute log and analyse it, it can be longer or shorter than this. I know this isn't helpful! It doesn't seem to be an exact science. I think it also depends how high or low the blood glucose is at the time, and whether it is moving rapidly up or down. I'm afraid it is trial and error! But taking account of meter inaccuracy and those sort of things, you can usually calculate an average of how much higher or lower it is reading over a period of a few days.

Thanks @Boo1979 and @Bluetit1802 suspected it might be a ‘depends’ answer.

Going to be very interested in the data.

Enjoy! I am a part time user, but find one is invaluable when I'm on holiday, especially as we go away 6 times a year, a week each time in holiday cottages. No more wondering what's happening when we are out all day, no need to test when eating out etc etc. I love analysing the data. I use the Freestyle app on my PC so I can see it properly. Other than one very wild one, all the rest have been consistent although reading a bit low - not drastically. Maybe averaging half a mmol/l.

One tip, if it is possible for you, ask someone to attach it for you. I find they stick better that way. None of my 10 have fallen off. It isn't as easy trying to do it on yourself with one hand.

Thanks. I’m not planning on being a regular user either.

Yeah, yeah.
You say that now.
Just wait for the profound sense of loss and worrit that sweeps over you as the first sensor expires...

Seriously though, they are a fab tool. Just don’t fixate on the number accuracy (because that will just make you annoyed at discrepancies). Instead, focus on the graph line, the ups and down and the speed of those ups and downs.

Like bluetit, I find them most useful when away from home and outside my own kitchen. Holidays. Work trips. Etc.

I also find that it is much easier to exert self control knowing I am going to have to watch the results on the screen.

Exactly my feelings when each one expires and I know I have to wait several weeks for the next one!

I'ver found that I have to wait 48 hours between insertion and activation. Otherwise it registers rather dramatic lows overnight, especially if I sleep on my sensor arm. After that it's fine! In general most of mine have read lower than finger pricks, but patterns are similar - though obviously mch more detailed.

I activate mine straight away, but I never was good at deferred gratification. My preference was confirmed when I put one on, and because the sensor hadn't gone in properly, it didn't work. Imagine that happening after 24 hours, I'd be so annoyed.

I can understand the argument for waiting before activating, but I like to ceremoniously remove the previous one, make sure the skin is happy underneath, before applying a new one. So I'm an activate now person.

Just do what I do, alternate arms.

I do, I just like to finish with the old before I start the new. It's not rational, it's emotional.

My first sensor is due to expire tomorrow around 11 am So far i have found it useful especially the arrow indicators letting me know if I am steady falling or rising

Anyhoo; do most folks simply wait until sensor expires then put a new one on a different arm of course. Or do folks tend to put one on the day before, and just not activate it, until the first one expires??

Any thoughts would be appreciated

I do the latter. Actually two days at the moment. My sensor runs out on Saturday mornings, I put the new one on Thursday morning.

Took your advice Barry and applied it earlier tonight. It is so simple to apply and no pain whatsoever.

I can only wish that this will be rolled out quickly to all those type 1 that want it. Hopefully it will make managing their diabetes that much easier
