Designed to measure whether the metal enclosure of 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.

Includes:

• Power cord
• Spare fuse
• Shorting bar
