The USDA-FGIS releases new grain moisture calibrations twice a year — once in the spring and once in the fall. Loading the update takes under a minute. Here's the full walkthrough for the GAC2700 UGMA and AGRI. The short answer To update your GAC2700, load the current USDA-FGIS calibration bundle from a USB thumb drive: open the hamburger menu → Calibrations, insert the drive in a front USB port, select Calibration Bundles → Load New Calibrations, and confirm. The tester automatically clears the old calibrations and installs the new ones. Then pick your commodity and keep testing. When should you update your calibrations? Twice a year, as soon as each release is available. The USDA-FGIS publishes updated calibrations in the spring and again in the fall, ahead of harvest. Commercial locations typically load the new bundle before harvest or in the spring so every reading stays as accurate as possible. Before you start: download the current calibration bundle and copy it onto a USB thumb drive. Loading a full bundle replaces every calibration on the tester, so you don't need to remove the old files first. How to load a calibration bundle: step by step 1 Open the calibrations menu From the home screen, open the hamburger menu and scroll down to Calibrations. You'll see options to delete all calibrations, export them, load one at a time, or load a full bundle. 2 Insert your thumb drive Plug the USB drive with the new calibration files into either USB port on the front of the tester — it doesn't matter which one. 3 Load the new bundle At the top of the screen, select Calibration Bundles, then the Load New Calibrations button, and confirm Yes. The instrument loads every calibration from the drive and deletes the older ones already on the tester. 4 Remove the drive and resume testing Once it finishes, remove the thumb drive, return to Home from the hamburger menu, choose your commodity, and continue testing. Frequently asked questions How often should I update GAC2700 calibrations? Twice a year. The USDA-FGIS releases new calibrations in the spring and again in the fall. Update your analyzer as soon as each release is available. Does loading a bundle delete my old calibrations? Yes. Loading a full calibration bundle automatically removes the older calibrations on the tester and replaces them with the new files from your thumb drive. Which USB port do I use? Either one. Both USB ports are on the front of the tester and it doesn't matter which you use. Does this work for both the UGMA and AGRI models? Yes. The same process applies to the GAC2700 UGMA and the GAC2700 AGRI moisture analyzers. Still have questions? Our team can walk you through it. 312-738-3700 seedburo.com
