Drifting Electronic Scales

I currently have a Gempro 300 electronic scale that I purchased a few years back. I think it was like $325 or so. The scale seems to be accurate, but has a real problem with drifting. I am constantly re-zeroing the scale and wondered if this was just something that is common to these types of scales. My door to the room is closed and the a/c or heat is off in the room when I reload, so I don’t believe they are a factor. Is there a scale that would better serve me, without all the drifting, or will minimize it, or is this just the nature of the beast, so to speak. I’m sure that I can get into some ridicules price range and eliminate the drift, but lets say under $500..
 
Before you write off the scale, try wiping it down with a NEW dryer sheet. Static electricity is a real problem for most of these scales, and the dryer sheet will help quite a lot.

You are not the first person to experience this problem either.

Do a search for ''dryer sheet" and prepare to be amazed.

Keep us posted with results.

+ one for the dryer sheet. Also wipe down the cup and table/bench.
Another factors is proximity to flourescent lights. LED solves this.
I installed clip-on ferrite ring RFI Noise suppressor cable clip on the electrical wires (Amazon). Some help.
Consider and anti-static mat under the scale.
But what really solved my drift problems was to let the scale warm up for at least an hour before use.
 
The wipes are imperative/good IMHO. I found on several electronic scales I have had just leaving them on 24/7 takes away the tendency to drift. I use to do the turn on 30 minutes prior thing and had it frequently. Now I no longer see that.

I will try the dryer sheet trick. The scale sits on an anti static mat and there is one of those things on the power cord. Thanks so much.
 
With the discount I got this one for $500. As good as any and better than many.

I have looked at this one previously, if the dryer sheet and static guard ideas don’t work, it may be a consideration.
 
... & my RCBS 505 just keeps on working. No worries about static, fluorescent lights, doors being open, phase of the moon, power failure, turning it on 30 minutes ahead of time, etc.

Serious question. What is the reasoning behind electronic scales? Does that extra decimal place accuracy (when it works) really make a difference on the target? Are they faster than beam scales?

I think the main reason for the electronic scales is that all of the automatic powder dispensers use an electronic scale. My 505 works great to, and I use it to set up my thrower for ball powder charges. So unfortunately if you want to use an auto powder dispenser, you might have to deal with this issue.

For me, it's about accuracy and consistency, which I find the FX-120i does very well.

Does that extra decimal place accuracy (when it works) really make a difference on the target?
Yes. See the pic of my experiment below.

But, for each of us, the question is . . . does the difference matter?

Are they faster than beam scales?
Yes. Particularly if you take the how fast you can throw and trickle out of the equation. . .???

Your Gempro will run on battery power. Does it drift only on AC? If so than you have outside the scale induced drift, usually voltage fluctuation. Physical vibration can also drift, as well as short range radio signals. I run my RCBS plugged into my LED lights and have very little drift, I let it warm up for 10 minutes. Calibrate and run.

My AutoTrickler/FX120i doesn't drift and is much faster than your beam scale just as accurate too. My SDs are very low too. 20210414_184506.jpg

Big +1 on this!
On my bald eagle scales I found it helps to take plastic scale cover all the way off and get it away from scales. I use a metal table and I set my scales on 2x8’s to reduce interference also.

Thanks for the reply. Are your 40.9gr throws just powder measure throws, or did you trickle up to desired weight?

Also... why would we want to take how fast I can throw & trickle out of the equation if the question is speed to complete a task?

I dont load large quantities at a sitting. Small batches of 20 rifle or 50 pistol is the usual.

The point of taking the throw and trickle out of the equation is to equate just the difference in the speed of the machine itself.

Like the FX will give you a final weigh measurement much faster than a beam scale. . . .even if you're trickling. ;)
