There is a newer, and in my opinion much better, video guide to inserting Medtronic's Enlite glucose sensor available on YouTube from Medtronic Diabetes ANZ. This version not only describes the basic insertion steps but also talks about things to not do and describes some ways in which things can go wrong during the insertion process.
If you are interested, please follow the link below to my post in the Continuous Glucose Monitoring Forum.
Of the errors I receive on my pump, the CAL ERROR is by far the worst. If the Meter BG/ISIG ratio is not good, it is pretty much impossible to recover from without inserting a new sensor. And the problem is, my ISIG value sometimes goes down for what seems like no reason, and I can’t figure out how to prevent that from happening. I have learned from previous forums that sleeping on my stomach (pressure on the sensor) can cause low ISIG values, but this is happening in the middle of the day or even the evening when I have been out of bed for many hours. Does anybody have any ideas as to why this might be happening?
Very old topic, but I’ve been having the same issues since day 1, njsokalski. Try the dexcom if you can; they are a much better product. I think the underlying issue with the Enlite is the fact that the transmitter has leverage against the sensor. If it gets bumped, or just touched by your body during normal activity, it will likely move the sensor inside your body. That seems to be what support alludes to if you call them.
Thanks I didn’t know about the cal factor but it sounds right. I used the 530g for 3+ years and am now using the 630g. So by just experimenting, I found a few tricks. I put in a new sensor first and turn off the sensor function of the pump. I mark the time and after the two hours (the timer is in the transmitter - independent from the pump) I check my bg. If it’s not too high or low and not rising or falling much, I turn on the sensor function and tell it to find the new sensor. In a minute or so, the pump wants me to calibrate my sensor.
If my bg is fairly stable, I calibrate again in 2 or 3 hours. I generally calibrate at least one more time the first day. The accuracy isn’t at its peak yet, but it gives me a good idea of where I’m at.
I’ve had the same problem with accuracy the first 12-24 hours. I’ve been using the 670G for a month now; had similar problems with the 630. I didn’t know about the “cal-factor”. I will definitely try this with my next sensor change. Thanks for sharing.
