Have you ever dreamed that all of your tinkering, fussing, and fiddling in the shop and on the road could help improve every road in Minnesota? Do you or your maintenance staff need funding to develop an idea to improve your sign maintenance and installation process? Or maybe you’ve come up with an idea for a new tool for controlling roadside vegetation or a design for a more effective work-zone safety product. Whatever it is, the Local Operational Research Assistance (OPERA) Program wants to hear about it!

The purpose of this guide book is to provide easy-to-use steps for calibrating snowplow sander controllers. It is an experience-based guide that captures tips and techniques learned by experienced calibrators. It helps agencies calibrate their sander controllers so the correct amount of salt, sand or other solid material is applied to the road when treating roads during winter maintenance. The guide also includes calibration forms, and a general discussion about calibration.
