Description
M-140RMS Mini AC Leakage Current Clamp Tester
The MULTI M-140RMS Mini AC Leakage Current Clamp Tester is a compact True-RMS clamp meter designed to measure AC leakage current and AC current. It provides selectable measurement ranges for low-level leakage current and higher AC currents, with a 40 mm jaw opening and a maximum measurement range of 400 A.
The M-140RMS features a 3.5-digit LCD with a maximum reading of 3999, data hold, and automatic power-off after approximately 10 minutes. Its compact dimensions of 64 × 162 × 23 mm and approximate weight of 125 g make it suitable for portable measurement. The instrument complies with IEC 61010-1 and IEC 61010-2-032, with safety ratings of CAT II 600 V and CAT III 300 V.
