The essential on-site tool for electricians and maintenance professionals. Fireduard-Meter transforms your iPhone into a professional-grade circuit analyzer. Unlike basic home power monitors, this app is engineered specifically for fault diagnosis, historical comparison, and field reporting. 1. Circuit Health Diagnostics * Select any circuit and compare real-time power curves against a historical baseline (e.g., 7 days ago). * Instantly visualize deviations to pinpoint anomalies such as sustained high power, abnormal night usage, or load loss. * Generate detailed diagnostic reports for troubleshooting. 2. Field Fault Logging * Document physical faults directly on-site. * Take photos, add descriptions, and assign custom titles to each fault record. * Build a searchable archive of past issues for future reference. 3. Dedicated Workbench * All professional tools are centralized in the Work module. * Keep your diagnostic history organized in a single, searchable report list. * Export or review past diagnoses with full chart data preservation. 4. Precision Data Analysis * Compare power curves at minute-level granularity (1-minute data points). * Support for non-continuous data – missing points are handled gracefully without breaking the chart. * Zoom and pan through curves to inspect any time window in detail.
