I just bought an RCBS rangemaster and its not wanting to stay calibrated. Exaample: drop a charge in the pan, get wieght, load case, put pan back on scale' scale reads -0.2. Sometimes it re-zeros most of t5he time not. I use the calibrating wieghts and it reads true but once you remove the pan the problem starts, most of the time. Is there a warm up time for these scales? It didnt come with the instruction manual. Any comments or ideas please. I did call RCBS and they said to return it with $35 and they would send me a new one no questions asked.That is cheap enough just thought I would check with you guys before I put it in the mail.

Very true, but I don't think many are aware.

Re: Scale not staying calibrated
Sometimes the drift is due to noise on the AC line the scale is plugged into (fluorescent lights, computer etc). Try a different socket and circuit just to see if the drift is still present.

Re: Scale not staying calibrated
Poor quality surge protection, florescent lights, cell phones and static electricity are all trouble makers

I find it interesting (or disturbing) that so many people have problems with their Chargemasters. Mine doesn't drift a tenth of a grain ever. It is 4 feet below a florescent shop light and in my garage which isn't that temperature constant. I have a solid bench anchored in the concrete foundation of my garage and I think that helps a lot. Also, I once had a problem with wacky, seemingly random reading, but it turned out to be a few grains of Varget down in the load sensor hole under the pan. I blew it out with some computer "dust off" and it was back to its normal 100% reliable self.

Re: Scale not staying calibrated
Well my room temp is fairly consistent there is fluresent light apx. 8' away. I turnedit on last night and left it. I hope it's just me not letting it warm up.

Re: Scale not staying calibrated
thanks to everyone for the info. It was me. Once I let it warm up it worked just like it is surposed to.

Re: Scale not staying calibrated
I still use the old Lyman 10-10 beam as I had a bad experience using electronic scales with pistol powders a few years back.
Will buy another electronic scale for rifle to use at the range, but keep the Lyman 10-10 for checking. Although electronics are lovely, tried and proved are hard to beat.I like em all.

Re: Scale not staying calibrated
I tried an electronic scale in my garage and its a no go; drifted in non-predictable rates. Abandoned the scale and went back to a Ohaus 10-10. Works every time, no matter the lighting or moderate drafts.

Re: Scale not staying calibrated
I just ordered a 5-0-5 from Scott Parker. My Lyman 1200 has been getting more, & more erratic by the day. Worked fine for several years but now Im done with electronic scales.

Re: Scale not staying calibrated
Scott's scales are the standard I go by and never let me down and if you use a digital scale I think it's almost a necessity to have another scale to use to double-check it and keep it honest as those digitals can be sketchy.
