Its Cold and BG Meter Wont Start

First thing to mention here is that I am in Australia, and we are in the middle of winter.
My mother’s meter registers ‘error’ on cold mornings.

How do you warm up your machine to ‘get it going’ ?

Get central heating.

When I worked in the winter I would just keep close to my body underneath the layers. Put it underneath your pillow or maybe near something warm like coffee maker.

Always in a pajama pocket. Same with Dexcom.

Ditto what everyone said here. Body warmth is sufficient to keep your meter operating. I leave mine in my pants pocket.

Cheers, Mike
