Instructions on how to calibrate a FX-120i Lab Balance. You will need a 100gm class F1 calibration weight. I Paid $18 through this seller on eBay. m.ebay.com/itm...
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.
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.
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.
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?
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.
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.
