Cardinal Scale manufactures several diagnostic tools for our authorized scale dealer technicians to assess and diagnose their customer's scales during service calls. Cardinal Scale’s SmartCan diagnostic tool is an analog-to-digital load cell junction box for new or pre-existing truck scales, railroad scales, floor scales, and batching systems. SmartCan provides real-time diagnostics and identifies load cell problems before they cause inaccurate weighing, so scale downtime is minimized. Additionally, Cardinal Scale's iSite cloud-based software provides remote monitoring for the SmartCan system and sends e-mail and/or text alerts, so scale diagnostics can be assessed from any location. iSite is a particularly potent tool when coupled with ARMOR truck scales, since dealers can view truck scale issues from a PC, phone, or tablet. The NEST diagnostic toolkit provides fast, accurate, and ultra-portable truck scale diagnostics for truck scale dealers. The NEST can expediently view individual load cell readings and check the home run cable and load cell cable connections.
