Clamp meters: AC or AC/DC, and how to choose the range

An AC clamp reads alternating current. An AC/DC clamp is a different instrument when the circuit is a DC bus, a battery string or a drive output that must be measured as DC. Leakage current is a third job, usually at milliamp resolution, and it needs a leakage clamp.

Kyoritsu KEW 2117R is listed as an AC clamp meter with a fully safety jaw, 0.01 A resolution, and True-RMS auto-ranging of 60 A, 600 A and 1000 A. Use that range list when the feeder current sits inside 1000 A AC. The catalog line does not print the jaw opening in millimetres, so confirm the conductor size on the datasheet.

Metravi 4673 is listed as a TRMS AC/DC leakage current clamp meter. That is the shortlist for leakage, not for a 1000 A feeder. Metravi 307N is listed as a digital clamp-on power meter. Fluke 301A is listed as a compact pocket clamp meter. Read each line for AC only or AC/DC before you mix them into one kit.

Send the part number and the conductor size you need to clamp. Vishal Electricals in Chickpet will quote the model whose datasheet matches that current and that jaw.
