Overview
The DFS200 is a handheld AED tester for inspection and maintenance personnel. It performs comprehensive AED functional tests including defibrillation shock waveform identification, energy (joule) calculation and AED battery voltage measurement. The tester connects via Bluetooth to a dedicated mobile app for cloud-based maintenance management, enabling real-time tracking, test scheduling, data synchronization and communication between managers and field technicians. The device also supports fully standalone operation without a smartphone or network for flexible on-site use.

Features

• Defibrillation Test: identifies multiple defibrillation waveforms and computes delivered energy in joules; configurable adult and pediatric energy pass criteria.
• Multiple ECG Waveforms: offers various ECG waveforms for AED defibrillation simulation and supports custom waveform storage.
• AED Battery Measurement: integrated multimeter for battery voltage measurement, with capability to measure under load (optional probe).
• Standalone Mode: lightweight (330 g) portable unit able to perform basic tests without app or network; one-handed operation and pass/fail indicators based on custom thresholds.
• Custom Waveform Import: import and store user-defined waveforms for standalone testing and common ECG signals.

Highlights

• Bluetooth Low Energy connectivity and dedicated mobile app for remote control, test data saving and CMMS integration.
• Automatic saving of test records including shock energy (J), waveform traces, battery voltage and timestamps to build a test history.
• Optional PC software for rapid verification, waveform import and report generation.
• Portable, battery-powered standalone operation enables fast field verification without internet access.
