The Extech EX330 can detect the presence of AC voltage (from 100 to 600VAC) simply by being held very near to a voltage source. The meter will automatically turn off after 15 minutes of inactivity. This will conserve battery energy. To turn the meter on after an Auto Power OFF, simply turn the rotary switch to OFF and then back to the desired setting.The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current, etc. can be stored so that subsequent measurements can be made in comparison to that value. The displayed value is the difference between the reference value and the measured value. The icon will appear in the lower left-hand corner of the display when the battery voltage becomes low. Replace the batteries when this appears.

True RMS & Enhanced Diagnostics

Part of the Extech’s precision is its True RMS functionality. It can be very difficult to make accurate current and voltage readings in industrial and commercial applications when electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic systems can distort the AC waveform, making it hard for averaging meters to get an accurate read. True RMS uses a more advanced formula to compensate for this kind of distortion. In addition to its high performing, 100 kHz ACV bandwidth that paints a more detailed picture of measurements, the MM570A offers a wide array of frequently used functions: maximum/minimum recording with autoranging, Auto Power off; Relative and Hold; and a robust Peak function that captures transient pulses. And, having two Type K thermocouple inputs make differential temperature (delta-T) calculations easier for R&D testing such as intake vs. exhaust component cooling tests or industrial and HVAC applications like superheat and sub-cooling measurements.

Other Features

Plant mechanics and electrical troubleshooters can be confident the meter is backed by a CAT IV-600V & CAT III-1000V overvoltage safety rating, protecting users even on devices connected to raw voltage distribution lines.

Extech’s DM220 is unrivaled in its combination of remarkable simplicity, multi-function versatility, pocket-friendly size, and robust CAT-IV overvoltage safety rating. The compact, autoranging Extech DM220 Digital Mini Multimeter is equipped with capabilities that are perfect for the electrical hobbyist, electronics tinkerer, or DIYer working on home improvement, automotive electrical, and A/V projects.

Functional Overview

Use the DM220 to perform more in-depth testing on existing and new home wiring outlet and lighting circuits and troubleshoot appliances like refrigerators and dryers as well as electronic devices found around the home and garage. With its small size and integrated test leads, it’s easy to have the DM220 handy wherever you are — even in a shirt pocket. Keep it in the glove box for on the road repairs. Handy for quick testing, use it to measure AC/DC voltage (to 600 volts) and current (to 200 mA). Measure resistance, capacitance, frequency, and duty cycle. Test diodes and continuity. To avoid fussing with selecting the right measurement range when working on a variety of components from small electronics to main electrical sources, the meter automatically adjusts with autoranging. This is especially useful when taking measurements that straddle the boundaries of two ranges.

Other Features

In addition to its electrical testing and flashlight functions, the DM220 adds even more value with a built-in non-contact voltage detector. You won’t have to search for a voltage pen in order to quickly and safely check for voltage prior to attaching the multimeter’s test leads to the device under test. A bright red LED alerts you to the presence of voltage whether the meter is on or off. And the built-in flashlight is great for looking into wall cavities, night-time roadside troubleshooting in or under a vehicle, or for illuminating dark basements, crawlspaces, and attics where lighting may be limited, unavailable or de-energized. In addition, the 4-digit, 4,000 count display is easy to read. Rarely seen in the pocket-meter category, the DM200 is backed by a CATIV 600-volt (CATIII 1000-volt) overvoltage safety rating, protecting users even on devices connected to mains/voltage distribution lines. Ultra-compact and ergonomically designed, the DM220 has a double-molded housing with storage clips to retain the integrated silicone test leads that stay pliable even when left in a service vehicle during the cold winter months. Buttons are sealed, membrane-style, to ensure dust-proof, trouble-free functioning.
