Superlarge Caliber Leakage Clamp Meter

The ETCR 7100A measures AC and leakage current from 0.0A to 4000A with 0.1A resolution. It suits electricians and maintenance engineers who need to verify cable insulation or transformer grounding flat steel up to 160mm × 4mm. The 108mm × 148mm CT aperture accommodates conductors up to 108mm diameter for direct clamp-on testing.

Magnetic Shielding Core And RS232 Data Transfer

A magnetic shielding core provides strong anti-interference ability to maintain accuracy and stability during measurements. The instrument stores 99 groups of data internally and uploads them to a computer via the RS232 interface for analysis, saving and printing. Power comes from four LR6 alkaline batteries (not included) housed in the handheld unit.

Extended Clamp Operation On Battery Power

The clamp design allows non-intrusive measurement on live conductors below 600V line voltage without circuit interruption. Four LR6 alkaline batteries deliver up to 12 hours of continuous working time for long shifts. Data hold and storage functions let technicians capture readings in noisy environments and review them later at a workstation.

Questions about this item

What does the RS232 interface actually let me do with the 99 stored readings?

The RS232 port connects the meter to a computer so the 99 stored data groups can be uploaded for reading, analysis, saving and printing.

Will the 108 mm by 148 mm clamp jaw fit the 160 mm by 4 mm flat steel grounding wire I need to test?

Yes, the clamp is sized to accept a 160 mm by 4 mm flat steel grounding wire as well as round cables up to 108 mm diameter.

How do I power the 7100A for a 12-hour session and what is the common mistake?

Insert four LR6 alkaline batteries (not included) for 6 V DC supply; the step people miss is forgetting to buy batteries because none are in the box.
