Description
The CM-03 Leakage Current Tester is a precise tool for electricians and industrial technicians. Its 3 3/4 digit LCD with 40-segment bargraph shows readings clearly. The meter has five AC current ranges: 40mA, 400mA, 4A, 40A, and 60A. This covers most applications and allows accurate detection of leakage currents.
The high 10μA resolution on the 40mA range ensures precise measurement of small currents. The shielded jaws reduce interference from stray magnetic fields. The built-in filter circuit minimizes high-frequency noise. The meter also measures AC voltage up to 400V and supports continuity and frequency testing.
The tester is designed for convenience. The 30 mm jaw fits easily in tight spaces. The fast bargraph display quickly shows transient currents. It features a single rotary switch, Max/Min recording, Data Hold, relative measurement, and 600V overload protection for safe operation.
