Description

Feature	Details
Product Name	Extech MA640 – 600 A True RMS AC/DC Clamp Meter + NCV
Type	Digital clamp meter + multimeter + built-in NCV (non-contact voltage) detector (FLIR)
Max Current Measurement	Up to 600 Amps AC or DC (DigiKey)
Clamp Jaw / Cable Capacity	1.5" (≈ 40 mm) jaw — fits large conductors / thick cables (up to ~500 MCM / 750 MCM / heavy-duty cables) (FLIR)
Functions & Measurements	AC/DC Current, AC/DC Voltage (up to 600 V), Resistance, Capacitance, Frequency, Temperature (via Type-K probe), Diode test, Continuity, Duty cycle, plus more — full multimeter + clamp meter combo (DigiKey)
Special Features	True RMS — gives accurate readings even with distorted waveforms (TEquipment) Built-in NCV (Non-Contact Voltage) detector with LED alert — for quick live-wire detection before contact (Test Equipment Depot) Temperature measurement via Type-K thermocouple input — useful for HVAC, motor, or heating-system diagnostics (TEquipment)
Display & Usability	6000-count backlit LCD (good for dim / job-site lighting), data-hold, auto or manual range, MIN/MAX logging, relative mode (zero-adjust for DC), compact/durable molded body for heavy duty use. (TEquipment)
Ideal For / Typical Use Cases	Electricians, industrial maintenance technicians, HVAC & mechanical engineers, building/electrical contractors — especially when working on heavy-duty installations, large cables or DC + AC circuits. Also useful for measuring voltage, checking continuity, testing capacitors, checking temperature, and doing safe live-wire checks with NCV.
Why It’s Useful	Combines many tools (clamp meter + multimeter + NCV + temperature probe) in one — saving cost & space. High 600 A capacity handles large loads or heavy-duty circuits. True RMS ensures accurate reading even in non-ideal waveforms. NCV gives safety advantages. Good for both AC and DC systems — versatile for industrial/residential/commercial work.
