Description
M-1141 Leakage Current Clamp Tester
The M-1141 Leakage Current Clamp Tester is designed to measure AC leakage current and line current, with five selectable measurement ranges from 30 mA to 300 A. Its 40 mm clamp opening allows measurements around conductors without disconnecting them, while the minimum resolution of 0.01 mA supports low-level leakage current measurement.
The tester features a 55 Hz band-pass filter that activates automatically at power-on, along with maximum value memory, data hold, and an LCD backlight. It complies with the EN 61010 safety standard, with measurement categories CAT III 1000 V and CAT IV 600 V.
