Description
M-220+ Mini Digital Clamp Tester
The M-220+ Mini Digital Clamp Tester is a compact AC current measuring instrument designed to measure load currents across two selectable ranges of 30 A and 300 A. Its 33 mm current transformer (CT) opening accommodates conductors within the specified opening size, while its compact dimensions and approximately 85 g weight make it convenient to carry and handle.
The tester features a 3.5-digit LCD with a maximum reading of 3200 and a Data Hold function for retaining measured values on the display, particularly when working in dark or hard-to-reach areas. It provides an accuracy of ±1.2% of reading ±10 digits at 50/60 Hz under the specified reference conditions.
