THNET-SPD-I type surge protector tester is a tester for testing the DC volt-ampere characteristics of the voltage limiting type surge protectors and switch type surge protectors used in surge protectors. The instrument has the characteristics of advanced technology, accurate testing, and simple operation.
The THNET SPD-I Surge Protection Tester is a dedicated instrument for measuring the DC I‑V characteristics of surge protection components such as MOVs, TVS diodes, discharge tubes and solid‑state discharge tubes. It complies with TB/T2311‑2002 and IEC61643 standards and uses a 16‑bit microcontroller with LED digital display for precise measurements.
The manual provides an overview of the device, detailed test methods for each component type, technical specifications, step‑by‑step operating instructions, safety warnings, and after‑sales service information. This manual is written in Chinese.
