The Hioki 3157 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)
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

*1:Note
1. Protective continuity resistance measurement for medical devices and general electrical devices
2. HGround 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

Model No. (Order Code)

3157-01	100-120 / 200-240 VAC switching

Note: This instrument is not capable of performing measurement by itself. Please purchase two Current probe 9296 units or one Current probe 9296 and one Current apply probe 9297, depending on your measurement application.
