Extech MM570A MultiMaster High-Accuracy Multimeter

Precision Testing Demands a Precision Multimeter

The Extech MM570A is the premier model in the MultiMaster series of precision multimeters and ranks among the best in the Extech digital multimeter line. Designed with an emphasis on high accuracy, high resolution, and sophisticated functionality, the MultiMaster offers an unrivaled range of capabilities suitable for bench work while also a robust and durable meter for electrical and electronics testing in industrial and automated manufacturing environments filled with sensors, servos, and controllers.

First-Rate Precision & Features

The full-range MM570A digital multimeter measures voltage, current, frequency, capacitance, resistance, and temperature (using its Type K wire bead probe) with high resolution readings down to 1ÎV, 0.01 ÎA 0.0001 Hz, 0.01 Ω, and 0.1 degrees. The frequency measurement mode is expanded with dual-range sensitivity for line (to 200 kHz) and logic (to 2 MHz) levels. Users can perform dBm measurements with 20 preset impedances. Duty cycle, continuity, diode testing are also included. It is hard to beat the MM570A's 0.02 percent basic DCV accuracy. For benchtop testing and field troubleshooting of precision electronic components, the meter provides superior measurement confidence. The backlit 6-digit display provides 50,000 count readings and an astounding 500,000 counts for DCV and frequency measurements. A useful segmented bar graph simulates analog testing and quick "needle-swing" tests. For convenience, the meter recalls the last function used when powered up. You can expand the versatility of the MultiMaster with optional Windows-compatible PC communication software and optically isolated cable to transfer, manage and analyze readings on your computer.

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-1000V overvoltage safety rating, protecting users even on devices connected to raw voltage distribution lines. Measuring 7.32 x 3.42 x 1.39 inches (HxWxD) and weighing 12 ounces, the MM570A comes with heavy-duty test leads, Type K bead wire temperature probe, 9-volt battery, protective holster with stand, user manual, and a three-year limited warranty. NIST calibration is also available.
