Mm Cgms - Cal Err

[Raisin]

I'm using MM's newest sensors (the ones that do not need to refrig). B4 this version, I always used a sensor for 9 days. The first sensor based on the new version only lasted a little over 7 days. When it "died" on day 8, it started giving me a CAL ERR. I'm on my second sensor and I started the 7th day (3rd cycle). The ISIG reading before bed last night was a little over 9. I detached the sensor this morning, then told the pump that I was starting a new sensor and reconnected the transmitter to the sensor. After the two hour startup,
I put in my BG reading. After 15 minutes, it gave me a CAL ERR. What is wrong with these new sensors? Is anyone else having similar issues with these new sensors not lasting as long as the previous version? I don't understand why the sensor was providing accurate readings up to the point that I told it to start over, then it's first reading is a CAL ERR. Any advice would be appreciated.

When you remove the transmitter on the 7th day do you recharge it ?
I found that makes the difference.

I have had the cal error once or twice before. Usually, I have had it either when the sensor is ready to be taken off, or when my BG is rapidly changing. According to the manual, if you get a cal error you should wait until your BG stabilizes and try again.

when i want to restart the old sensor I dont disconect the transmitter ...I just go to start new sensor and in about 2 min s it say enter meter BG you dont have to wait the 2hrs .
