Features
Comprehensive RCD & Loop Circuit Testing
The JDDM9502 allows you to test not only basic voltages but also loop impedance and RCD performance (trip time and current) — essential for verifying protection systems and ensuring compliance with safety regulations.Wide Voltage Range Compatibility
With support for AC 85–265 V, this unit is suitable for a broad variety of global installations and mains supplies, making it highly versatile for use in Lebanon and regionally.True RMS Measurement for Accuracy
The inclusion of True RMS measurement ensures reliable readings even in distorted or non‑sine wave conditions — an important benefit when working with modern electronic loads or variable‑speed drives.True Data Logging & Back‑lit LCD Display
The back‑lit display ensures legibility in poorly‑lit job‑site environments, and the data‑saving feature means you can capture and review test results — useful for documentation, certification or service reports.Compact & Portable Design
With dimensions of approximately 194 × 78 × 37 mm and powered by AAA batteries, the device is easy to carry around site, manoeuvre into panels and use in tight spaces.
