The 227-4324 Digital Multimeter Gp (Clamp on) allows the technician to perform accurate and reliable measurements on electric power generation equipment. The multimeter handles current component analysis for AC and DC circuits up to 2000 amps.

Features and Benefits

The digital multimeter group features autoranging and autozeroing functionality for quick and easy use.
The clamp on design measures current without a direct electrical connection.
The digital multimeter group quickly handles the standard Ohms, continuity and diode tests.
True root mean square (RMS) measurements can be made on complex and distorted wave forms.
The digital multimeter group also measures the maximum RMS surge and retains the data.
This digital multimeter group has an analog port for connecting the meter to a data recorder, to a logger, or to an oscilloscope. The analog cable comes with the digital multimeter group.
