Combining cutting-edge power technology with intelligent control, it delivers efficiency, reliability, and user-friendly operation, making it ideal for industrial and laboratory applications.
Key Features
1.High-Speed Microcontroller Control
Equipped with a high-speed microcontroller, the ZXR-20A ensures automated operation, simplified workflows, and enhanced accuracy. Its intuitive touchscreen interface allows seamless control, minimizing manual intervention.
2.Multi-Current Output & Wide Measurement Range
With six test currents (<20mA to 20A), the instrument accommodates diverse testing scenarios, from small components (10Ω–20kΩ) to large transformers (100μΩ–1Ω). Accuracy ranges from ±0.2% to ±0.5%, backed by a resolution as low as 0.1μΩ.
3.Robust Safety and Protection
Advanced anti-interference algorithms and surge protection mechanisms safeguard the device against reverse electromotive force (EMF) impacts. Audible discharge alerts and visual indicators further prevent operational errors during discharge cycles.
4.Energy-Efficient Design
Intelligent power management ensures minimal energy consumption and reduced heat generation, enhancing both durability and environmental sustainability.
5.Enhanced User Interface
A 7-inch high-brightness touchscreen supports clear visibility under strong light and offers bilingual (Chinese/English) operation. Real-time data is displayed with 4-digit resolution for precise analysis.
6.Data Management and Connectivity
Store up to 1,000 test records with timestamps via its built-in storage. The device also supports RS232, USB, and wireless communication (via Android app), enabling data export, U盘 storage, and direct printing via its integrated micro-printer.
7.Remote Control Capability
Users can operate the tester remotely through a dedicated Android app, streamlining data acquisition, storage, and cloud uploads for collaborative analysis.
