600A True RMS AC/DC Clamp Meter + NCV
True RMS AC/DC Current Clamp Meter with Built-In Non-Contact Voltage Detector
Extech MA640 600A True RMS autoranging AC/DC clamp meter offers plant maintenance techs, electrical troubleshooters, and DIYers a test instrument that delivers a high level of performance and value. In addition to a host of advanced multimeter and current measurement capabilities, it also features a built-in, non-contact voltage (NCV) detector. Whether you are performing amp readings in a heavy-duty industrial setting or doing commercial electrical work, the 600A rating and ample 1.5 inches (40mm) jaw opening can accommodate most jobs, swallowing conductors up to 750 MCM. The large, illuminated, dual display is useful in poorly lit job sites, and the 4-digit (6,000 count) readout is complemented by a bargraph display to simulate an analog display. You can operate the meter with one hand, having a thumb-dial selector that is ergonomically placed off the side of the meter. The heart of the MA640 is an advanced digital multimeter. You can select auto- or manual-ranging and measurement functions cover all types of troubleshooting over and above noninvasive current probe measurements: voltage, resistance, capacitance, frequency, duty cycle, diode and continuity tests. Even measure temperature with the supplied Type K bead wire probe. Comes with test leads, 9-volt battery, carrying case, user manual, and manufacturer's one-year limited warranty on parts and labor.
