A complete portable weigh-in-motion (PWIM) system consists of a pair of weigh-pads (one for upstream and the other for downstream), a controller which translates raw load signals to WIM data, and an optional external battery pack. The weigh-pad dimensions are one foot wide and 24 feet long, covering two lanes. This document describes how to install and remove weigh-pads using the recommended tools and setup of the controller. The operation of controller that includes initial setup and calibration is described step-by-step. The controller stores WIM data in the controller hard disk using a comma separated values (CSV) format; the details of the CSV file naming convention and column formats are described.
