How to Calibrate a A&D FX-120i LAB Balance Scale

[@barndweller4573]

Thank you, just got my scale today and was reading the manual and could not understand, you made it simple!

[@chrismalterre1754]

Thank you Joe, this video made calibration super simple.

[@ctclimberguy34]

Ok, thank you ! I love that FX. Now I realize just how slow reloading was before the FX.

Just had to recalibrate mine thanks for the video. Mine was off by .14 grains

Go to a place that does countertops and ask for a piece of scrap granite. If they don’t have that, Corian is a good substitute. You can usually get the cut out from the hole they make for sinks for free, or a few bucks. It will insulate the balance from any vibration.

Good info, but you should be using a tweezers or hemostat type tool to pick up the weight and set it on the scale. Oil from your skin will add weight and make the calibration weight out of spec. I use to calibrate lab scales and you don't touch the calibration weights ever with your bare hands.

Subscribed! Thanks for the video :)

lol.... "opens window, lets make a precision weighing video"

[@treeratbuster]

Brilliant. Thanks. The owners manual is a bollix to understand.

Where/how are you setting your total charge weight? On the scale or by tuning the trickled? I would assume you set the scale for the desired charge weight?

[@joeambartsumyan7259]

maxpowerdog you dispense and trickle the initial charge manually then press print button and the scale remembers and repeats till you hit stop.

Joe Ambartsumyan How do you hit stop?

[@joeambartsumyan7259]

raythemanroe if you look in the video, I’ve used a red and green sharpie to mark the start and stop buttons. Mode is stop and print is start.

How do you calibrate without a calibration weight.

[@dabernathy15000]

Thanks!

[@amarshall621]

Joe, is that ebay seller ok? does it show up reasonable quick coming from china?

[@joeambartsumyan7259]

Austin Marshall plenty of people have ordered from him based off my recommendation and they have all received it in a reasonable time frame. Takes about 1.5 weeks to get.

[@ctclimberguy34]

You are calibrating for 100 grains but your little grey pants is on there. Wouldn't that add to the 100gr & cause your calibration to be off?

[@joeambartsumyan7259]

No because you zero the scale with the pan. The pan is invisible to the scale at that point.

[@nosuds]

Joe, what kind of trickler is that?

[@joeambartsumyan7259]

Jeff Dill autotrickler with autothrow.

[@nosuds]

Thanks I was looking to get the RCBS Chargemaster but I am not convinced that is the best bang for the buck especially from the accuracy point of view. Thanks again also for your great video.

Mention the price

Don’t touch the weights with bare hands. Use a fresh pair of unpowdered nitrile gloves or a brand new pair of those cheap, disposable cotton gloves. A good idea to remove the weigh pan and wipe it clean with a dry microfiber cloth from Harbor Freight. Anything that could transfer unseen grit, fingerprints, or powder residue to the calibration weight should be eliminated. The scale could be dirty when calibrated, doesn’t really matter, but you don’t want anything, even the most minute dirt or dust transferring to the cal weight and then going back into its storage container. I don’t recommend tweezers for the average guy. Just too dang easy to drop the weight and then you can’t trust its calibration after that.

Typo.. "grey pan"...
