Description
Hioki 3157-01 AC Grounding HiTester
The Hioki 3157-01 is an AC ground bond tester designed for protection circuit testing of a wide range of electrical equipment, including industrial machinery, medical equipment, and measuring instruments using a constant current system, enabling it to provide stable output current.
Key Features
• Easily perform protective continuity testing in compliance with international safety standards and laws
-1) Protective continuity resistance measurement for medical devices and general electrical devices
-2) Ground connectivity testing when installing electrical machine tools and distribution panels
-3) Testing of protective grounding and isopotential grounding work for medical equipment
-4) Evaluation of contact status using large currents
• Feedback control system that is capable of applying a stable current even with a fluctuating load
• Soft-start function that checks the connection to the device under test before applying the current
