Lyman 1200 DPS II?

What's y'all experience? Last night it seemed to go nuts. Everytime you set the pan on the scale it was off zero. Would push the 'Cal 0' button and would 0, however, it did throw some charges that were not weighted correctly. It is only 3 months old and is treated well.
 
Mine is working fine. How do you know it threw some incorrect charges? Did you weigh them on a different scale? A dumb question but did you recalibrate it. Did you let in warmup? Just a bunch of questions so I can watch mine to see if it is working correctly.
 
Sam: VERY GOOD QUESTION! since it is my scale how did I know? Some the charges filled the case to the top. How many others that did not do that were not correct, I do not know.

Wrong: I will check that, it has never acted this weird before, just would not stay on last night, I wonder about temperature sensitivity, it is HOT out here in West Texas in the garge, about 95, that might be it.

General: Always give it the FULL 30 minute warmup and press Cal 0 several times during loading. It was just OFF the entire night.
 
Use your calibration weights periodically to check that the calibration is still holding.

Flourescent lights can play funny with electronic scales if they are in close proximity or directly overhead.

All scales are not created equal. Some scales are not meant to be used for trickling a charge into. Others are.

Electronic scales are fragile. Even a short fall to the ground, or something landing on them, with no visible damage, can damage the unit.
 
Weird O Rama Bronco I moved the location of the DPS and it was more DIRECTLY exposed to the flourescent lights, da ya think it is THAT?
 
Hmmm, my work bench has a flourescent lamp directly over it/me and my scale works fine, everytime cept when I spilled some powder in the wrong place!

Flourescent lighting can affect the view of LCD displays, but I've never read of any affects on a scale's accuracy unless it's real close as in a few inches as opposed to being above the user's head where lighting would normally be. Nothing is mentioned in the manual or on the Lyman web site, please elaborate, thx.

None of the units were bothered by incandescent or fluorescent lighting, or by AC current running nearby.

Gonna give one more chance and back to Lyman, darn I hate that, it means spending about $130 buying an RCBS for while it is gone.
 
Wrongtarget may have the correct answer. I clean mine with canned compressed air after each use or when changing powder. After your post I checked mine today with a balance beam and another electronic scale and it is dead on.
 
I have the same scale, only the first version not the II. I used my scale under a florescent light. One reloading session mine did as you described after several sessions before with no problems. I cleaned it, turned it on, and same thing. Then I thought, I'll try it with the florescent off, even though it has worked fine until then. Once the florescent was off and I did another warm-up, it did fine. I have since stopped using it under the light and I have not had the problem again.
 
Make sure there are no powder granules under the pan. Also look at the bushings that hold the powder tube in. If they loosen up the tube will flop around and powder will spill and get under and into everything.

MarkA, I have had mine go crazy a couple of times. I have narrowed mine down to talking on a cell phone or getting a cell phone call in the same room that I am using my Lyman 1200 DPS.

What is the difference in the I & II? How laong has the II been out? Hope this helps. Dean-o
 
Mark you have had it three months and it is allready gone bad.cell phones and flourescent lights can mess them up, wait 30 minutes to let it warm up, and re calibrate during the loading. I will stick with my Ohaus 10-05 balance beam scales I paid around 40 dollars for back around 1979, I can have 50 hulls charged with powder and ready to load in that time. I tried the digitals a few years back, it took longer to do than on the balance and was not as accurate in my experience. I now use them to sort brass for a couple of my rifles.
 
You are talking apples and oranges comparing balance beam scales, drop powder measures, digital scales and combination powder measures/scales. And the different procedures for using them:
1) Balance bean and weighing each load.
2) Digital scale and weighing each load.
3) Setting powder measure with digital and droping each load.
4) Setting powder measure with balance beam and droping each load.
5) An automatic with measure and scale.
With forty plus years of reloading experience and having used ALL of the above procedures I now use the automatic. It gives me the best of the above procedures, weighing each load and getting rid of the inconsitant drop powder measure.
 
These kinds of questions are, for me, the strength of the internet. I found the answer of the bit of powder under the pan to be the answer.

I use it two ways.
A. Experimental loads, ladder loads, it is easier and MUCH FASTER to have it weight the loads in however many, ususally five in my case rounds and then increment it to next weight, ususaly 0.2 or 0.3 in my case.

B. Checking measure and spot checking large run of loads. My RCBS Uni has the micrometer adj and it STAYS PUT so getting on and staying on is easy.
