INDUSTRIAL APPLICATION
The UT272+ is purpose-built for telecommunications infrastructure, power grid substations, and petrochemical facilities where continuous operation is mandatory. In a cellular tower grounding audit, technicians utilize the Ø 32mm jaw to clamp directly onto the grounding down-conductor. This provides immediate verification of the earth loop resistance and detects parasitic leakage currents, preventing equipment damage from lightning strikes or electrical faults without interrupting service.
