DMMs measure up to 1000 V true RMS


Intended to reduce the need for additional auxiliary instruments, the AVO800 series of digital multimeters (DMMs) from Megger offers true RMS voltage and current measurement with basic accuracy of 0.1%. The series comprises two models: the AVO830 and the AVO835, which provide 600 V and 1000 V measurement ranges, respectively, across AC and DC voltage supplies. Both meters perform AC current measurements from 0.1 mA to 10 A.

The digital multimeters feature two-wire phase sequence detection to identify incorrectly wired three-phase circuits, motors, and generators. They also perform resistance measurement from 0.01 Ω to 50 MΩ, conductance and diode measurement, and 10 MΩ and 10 kΩ input impedance switching without changing the test range.

Each meter is outfitted with a 4-1/2-digit, 10,000-count display with a dual digital readout and analog arc. The AVO830 carries a CAT IV 600 V safety rating, while the AVO835 offers a combined CAT III 1000 V/CAT IV 600 V rating for use in high-energy, low-voltage electrical applications. Units are powered by two AA batteries that typically yield 150 hours of operation without the backlight.

The AVO830 and AVO835 digital multimeters cost $265 and $299, respectively.
