I love the cgms, however on days like today ..................... Sundays we insert a new sensor, later in the evening I start the sensor and calibrate, but after an hour sensor error, so I thought maybe it is not wet enough (about 7 hours after insertion). So, I turn it off. A few hours later I do new sensor, I calibrate, and then an hour or so later 3 h start! Today we already had at least 3 hour starts!!!! Is there a way to safe this sensor? Do you think i might not have inserted it deep enough? How much do you rotate?
