Extech have introduced the new MA620 (AC) and MA640 (AC/DC) 600A True RMS clamp meters, now available from TRIO  Test & Measurement. Designed as high feature, high value autoranging clamp meters, the new MA620 and MA640 clamp meters offer a host of advanced multimeter capabilities plus a built-in, non-contact voltage detector. The affordable new clamp meters are compact and easy to hold while offering a 40mm jaw opening.  The large, illuminated, dual display on the clamp meters is easy to see in poorly-lit job sites and features a 4-digit (6,000 count) readout complemented by a bargraph display. A thumb-dial selector is also ergonomically placed for convenient, one-hand operation. Depending on a user’s applications, two models of this True RMS Clamp meter are available: AC-only (MA620) and AC/DC (MA640).

The MA620 and MA640 True RMS clamp meters offer user selectable auto or manual-ranging plus measurement functions including: current, voltage, resistance, capacitance, frequency, duty cycle (dwell), diode and continuity tests – plus temperature using the included Type K thermistor probe. Convenient one-button functions on the clamp meters include: HOLD to freeze a reading on the LCD; MAX/MIN to track and display maximum and minimum values; and REL to activate Relative mode for “zeroing out” the meter which is useful for improving the accuracy of DC current measurements.

An additional safety feature is the built in to the new MA620 and MA640 True RMS clamp meters is a non-contact voltage (NCV) detector. The detector quickly identifies the presence of voltage on live wires and alerts the user with a red LED indicator. This feature eliminates the need for a separate tester. Both the Extech MA620 and MA640 True RMS clamp meters are CAT III rated and come complete with test leads, Type K bead wire temperature probe, 9V battery and soft carrying case.
