Altitude is EEPL’s Windows-based Base Computer System for its smart meter family (Single Phase, Three Phase, and High-Accuracy CT), providing secure, offline access for data reads, configuration, diagnostics, and firmware updates. It extracts full MRU datasets—billing, load profiles, tamper/event history, and comm status—while enabling commissioning tasks like billing cycle setup, time sync, and GPRS/RF/NB-IoT mode selection. Field-ready utilities include automatic UTC time-stamping, GPS geo-tagging, photo annotations, and job-ID–linked work-order sync. Data exports in XML/CSV flow seamlessly to AstrenEpp/MidasSynapse and technician workflows via ApexField, with audit-ready logs supporting regulatory and SLA needs. Role-based access, encrypted local storage, and complete interaction trails ensure enterprise-grade security. In short, Altitude is the direct, reliable interface between engineers/technicians and EEPL meters—ideal for pre-commissioning, diagnostics, and offline recovery.
