If you use a CGM that requires a “warm-up period” before the sensor is active, how often do you need to check your blood glucose level with a glucose meter during the warm-up?

I couldn’t say always because sometimes I’m sleeping, but otherwise it would be “always”.
Have the Dexcom’s G7 so warm up time is half an hour. I usually place the sensor and then remove the old one. The sensor starts warming up as soon as you apply so usually warm up period is 20 minutes or so. I do check accuracy with a finger stick. For me it’s best to start new sensor in the morning. Seems to be erratic if I apply in the evening.
I normally schedule my warm-up to be when I’m going to bed.
I look at CGM SG trends before I change, then depending what is going on I may check it once at 2 hrs and typically do a calibration after warm up. I try not to change sensor with an infusion set change because I always go up after a infusion set change.
The libre 2 only takes an hour to warm up. I check before starting the new sensor.
Sometimes, it depends on what my bg is at the time of the change. If I am near target (80) and “flatlining”, then no. But if I am lower or higher than I like and the trend arrows indicated change, then I use the meter at 1 hour (I use the Decom G6, so there is a 2-hour warmup).
Depends entirely on circumstances. Travel across time zones or other complications with eating times (meetings one cannot leave, etc) can produce a need to eat during the warm up period, especially if travel means the warm up time moves relative to mealtimes, Then I use meter before meal (or sometimes after) during warm up. Otherwise, only if I experience the signs I recognize as likely to be going low or super high during the warm up. G6 which has 2 hour warm up; I did not know G7 warm up was only 30 minutes, another reason to want to get it — but as a current G6 user who got it via Medicare, I’m not even allowed to buy it myself until they decide I’ve had it long enough!
Life happens and these questions are geared for people that are not independent.
Always because I don’t want to start out of my range which is between 70 and 140. I want to start around 100 and when the CGM comes on I know whether I will need to calibrate.
In order for the sensor to be accurate, I try to insert it during a time when my BG will be stable.
I chose rarely.
Not only during the warm up, but the first 24h with Dexcom G6 is always wildly inaccurate, and I need to check my bg with a glucose meter.
I use the G6 so I change sensor only when I will be awake during 2 plus hours warm up .. just in case some problem with warm up comes up.
I never checked with a meter during warmup for years, but now, I find my BG seems to rise drastically during warmup (likely the stress of not knowing my BG). I’ve become very sensitive to stress. NOW, I meter at least twice during the 2 hour warmup. Waiting on Tandem to support the G7 so I don’t have to do that anymore!
