#475 ANENG ANG860B+ Digital Multimeter

Specifications and notes on the ANENG ANG860B+ digital multimeter



I wanted another DMM for bench, and took a punt on the ANENG ANG860B+ Digital Multimeter. It’s available at a very nice price, and includes some more advanced features not always found on models in the same price range (µA, frequency, temperature). It doesn’t include transistor tester or inductance measurement (but I have other tools for this).

Thoughts after some initial testing:

  • very nice display
  • appears to be very accurate
  • I don’t like having the off switch on the measurement selection dial:
    • clunking it around every time to turn on the device is not very efficient, and I worry the switch selector will be the first thing to fail
    • I’d prefer a separate on/off switch, allowing the measurement selector to be left in the same position most of the time



  • Auto/manual ranges
  • True RMS measurement
  • 550V protection in resistance and capacitance ranges
  • Large LCD display,MAX display 6000 counts
  • Sample rate: 3 times per second
  • backlight
  • MAX/MIN data hold
  • Polarity identification
  • Low voltage indication
  • 20A high current measurement is available
  • Auto power off can be cancelled manually
  • Main measurements:AC/DC Voltage, AC/DC Current, Resistance, Capacitance,
  • Diode and Continuity Testing,Temperature, Frequency and duty cycle.
  • Weight: 420g
  • Measurement mode: Double-integral style A/D transform
  • Over range indication: OL
  • Working environment: 0~40°, relative humidity < 80%
  • Supply power: 3V (1.5V AA batteries * 2 Pcs not include )
  • Dimension: 18090.545mm
  • Accessories: User’s manual, a shockproof cover, a pair of test leads, a TP01K thermocouple

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
