Introducing the Hioki AC Grounding HiTester 3157

The 3157-01 AC GROUNDING HiTESTER is designed to measure whether the metal enclosure of an electrical equipment is connected to the ground terminal at sufficiently low resistance levels. It also can be used to evaluate the grounding conditions of large-scale electrical installations. Measurement is carried out by using a high current according to the specifications of the measurement object, and determining the voltage drop at the measurement point. Reference values are as set out in the various safety standards. The 3157-01 can carry out measurements in accordance with the stipulations of multiple standards.

Key Features

External I/O

The unit comes with I/O connectors as standard equipment. The connectors allow external START/STOP control, READY/TEST status checking, and PASS/FAIL result reading. Photocouplers are used to isolate the I/O signals from the internal circuitry.

External interface (option)

The 9518-02 GP-IB interface or 9593-02 RS-232C interface can be installed in the unit. This allows remote control from a computer as well as export of measurement data. The 9593-02 RS-232C interface also allows connection of the 9442 printer for producing a hard copy of measurement data.



Key Benefits

The 3157-01 passes a large AC current through the measurement object and measures the voltage drop according to the AC 4-terminal method, making it possible to measure very low resistance values.

  • Protective grounding checks of medical and general electrical equipment
  • Ground connection tracing of machine tools and wiring panels
  • Safeguard and equal-potential connection checks of medical installations
  • High-current behavior evaluation of connections
