curious how long you guys let your scales warm up? do any of you guys just leave them on all the time?
FX120i warm up time?

I allow at least 2 hours for my GemPro 250 to warm up. I am a retired analytical chemist and balances in the lab were always on 'standby' mode. It is good to have a standard or control weight to check accuracy. Incidentally, the GemPro 250 reads to +/-0.01 Grains.
I leave mine on 24 hours before using.

I leave mine plugged in. If I have time I like to turn it on and make sure it is level for at least 30 min before use (prefer 2 hours). I have also just turned it on and ran. I have a set of those Lyman check weights, helps a lot, takes the guessing out. I have only had to re-calibrate once so far during a session and was from cold start about 30 rounds in. But 30 min seems to be plenty of time so long as I don't unplug it.
What model are you using? A quick look at Amazon shows prices from $50 to over $200. I know next to nothing of line conditioners.
Curious, just received a Gempro 250... inline with some the questions here. New to ‘nice’ scales in general.
Being I’m in San Francisco area, I reload in my garage... not enough room in the house. The temp goes as low as low 50s in my garage, should I be storing my scale indoors (70s) and then bringing out when I reload and warm it up?
I’m also curious about calibration. Do you guys calibrate every single time, it doesn’t take that long, so I would assume you would every time the scale is turned on/off.

Perhaps this will add to the discussion a bit.
I usually warm mine up at least 30 mins prior to loading. A few weeks ago, I was loading and the wife had something come up that forced me to stop mid-lot (@ 50rds). After getting the domestics taken care of, I was beat, so didn't go back to lading until the next morning. When I did, I noticed it had drifted .08grs (not a whole lot, but still almost a .1 gr difference in a scale that is accurate to .02grs). At any rate, I had inadvertently left the scale on when this happened, so just rezero'ed the scale and continued on with the other 50rds in this lot of brass. When done, I decided to leave it on and see what happened. ...After a week, it had remained unchanged.
Now I leave it on all the time.

The Gempro 250 is still a strain gauge type scale. You will want to warm it up (leave it on) for at least one hour (2-3 is better) before you use it. I have it and it is a good scale, but still a strain gauge scale. Here is a good video about the 2 different types.
