gah, I got this thing recently, gonna use it for the first time today and the damn thing won't hold a zero

i zero it in, put in the little 30g weight, it reads 30.01, then the 20g goes in...50.02 ARGGGG

take them out and i'm left with either -0.01 and -0.02

tried it in multiple outlets, etc.

looks like i'm gonna have to send the damn thing back.

-and yes it has been calibrated to spec from the instructions included-

sounds pretty close

Never used one but a friend has just ordered one.

Is 1/100 of a grain really something that should be considered out of tolerance?

IIRC accuracy is to 0.1gr, I've not had any major problems with mine. yes, there is a little drift, that is the price you pay for tyhe convience of a electronic scale. I've used lab electronic balances that measured to 0.000x gram were housed in their own little glass housings, there was still drift.

Call RCBS first, and hear what they say.

My beam RCBS scale is good to .1 grain. Worked just fine for 30+ years.

I have one.  I helps if you let it warm up for about 10 minutes before you calibrate it.

I've been loading 30-06 ammo for my Garands.  I re-zero my scale after each 5 measurements.  It's a bit of pain but I'd rather be cautious than risk injuring the finest battle implement ever devised.

Turn it on, and go to bed.  Try it tomorrow.  I bet it will hold a zero just fine.  Never turn it off.  Works like a charm.

Rarely, mine seems to hiccup and I need to go through the calibration setup again.  But I’ve never had serious difficulties in getting it calibrated.

Suggestions:

Make sure the stable arrow is on for maybe 3 or 4 seconds before proceeding to the next step.  In theory you should be good to go the instant it comes on, but that hasn’t been my experience.

Let the unit warm up.   I’ve never had a problem with this, but other folks have.

Keep the unit away from air currents (even slight ones) and fluorescent lights.

Try to locate the two weights on the plastic weighting pad (or whatever it’s called) so that the total weight is as evenly balanced as possible on that pad.  A bit too much weight off to the side seems to cause a tipping action and a slight inaccuracy.

Mine did the same thing when I first fired it up. I let it stay plugged in an warm up a while and it seems fine now. I did call RCBS about it not going back to zero after weighing a charge, they said to just hit the zero button, no need to recalibrate after doing it at the start of the session, so it's pretty simple to just hit zero when it drifts.
