What is a Clamp Meter?
Clamp Meters are convenient measuring instruments that allow the measurements of current simply by clamping a wire while being energized without cutting a circuit. In cases of measurement by a Multitester and Digital Multimeters, the circuit must be cut to measure current. In contrast, with a clamp meter, current can be measured simply by clamping a live wire over its sheath. In addition to its simple operation, it allows safe measurement of a higher current (Use a type for higher current measurement such as DCM2000AD) since it is not directly connected to the circuit. Like a Multitester and Insulation Resistance tester, there are analog and digital types of clamp meters. The measuring range is typically about 20A to 200A or 400A both for DC and AC. As a special type, there are products allowing for the measurement of a higher currents of 2000A. Some types are also available to allow measurements of fine current of few milliamps for the purpose of detecting leakage current. Other allow
