Hey guys, I’ve been having a lot of issues with new sensors. I’m using the Medtronic Guardian sensor. I’m new to CGMs so please feel free to point out the obvious. I’ve used a pump for over 10 years, but this is a new ball game to me.
The problem I’ve been having is that I’ll connect the receiver to the pump, hook up the new sensor to the receiver, then my pump will say that it’s doing the warm up process and it will take up to two hours. Within that two hour period it tells me that the sensor has expired and to insert a new sensor. I’ve checked the sensor and it says the sites are still good.
How can the new site be “expired” if it’s brand new? Is there something missing here?
Thus far to fix the problem I put the receiver back on the charger, pull it off the charger when finished charging, reconnect it to the pump and then reconnect the receiver to the still new, freshly inserted site. I have had to do this two or three times which takes up to five hours of waiting time. I feel like I’m either missing something in the process, I’ve got potentially bad hardware, or this is big joke for how expensive these units cost. Any tips or ideas would be helpful. Thanks in advance.
