AM 5200-A Update Options (USA ONLY)


The USDA FGIS updates the UGMA Grain Moisture calibrations each May and August. Implementing these updates is mandatory for all USDA Official Grading facilities and all facilities using the meters for trade. We offer simple ways to ensure your instrument is up to date. The current calibration update is available below. The updates are typically made available 3 to 5 days before the implementation date.

  • Free download to your computer - Read these instructions prior to proceeding. Download the newest calibration file here.
  • Extended Plus Support - Send in your instrument. We'll update your moisture meter with any new software, calibrations, and inspect all hardware for wear or potential issues. Contact us for a quotation.

NOTE: Do not use these options for AM 5200-Farm Moisture Meters.
