Precision Multimeter - 6.5+ Digits of Resolution
Precision Multimeter - 6.5+ Digits of Resolution
Ever dreamed of designing your own high-accuracy, high-resolution Digital Multimeter (DMM)? Now you can — with Anabit’s Precision Multimeter Reference Design. And we’re not talking about another basic handheld meter. This is serious gear! We’re talking 6.5+ digits of resolution on DC voltage measurements. That’s microvolt-level insight into your circuits — the kind of precision usually reserved for top-tier lab instruments. if you do not believe us just check out the pictures where we compare its accuracy to a $4k Multimeter. This design supports a full suite of measurements, including:
- DC & AC voltage
- DC & AC current
- 2-wire and 4-wire resistance
- And even more multiple ADCs and measurement channels
Whether you're a precision measurement junkie, or you just want to build your own lab grade DMM, this is the perfect launchpad.
Check out the tutorial and get hands-on with the Anabit Precision Meter — your bench will thank you.

What Makes It Awesome?
✅ 32-bit Sigma-Delta ADC with > 26 bits ENOB — insane resolution for voltage measurements
✅ Auto-ranging up to ±200V, fully software-controlled
✅ Built-in multi-range current source — make precision resistance measurements without extra hardware
✅ Second 24-bit Sigma-Delta ADC — perfect for 4-wire resistance or custom measurements
✅ High-res precision shunt — measure current from 2 amps down to milliamps with ease
✅ Ultra-stable 2.5V reference, with optional 2.048V version for even tighter tolerances
✅Make measurement connections using the standard banana plugs or optional screw terminals
✅Jumper that allows you to select single power source mode or two power source mode (one for digital and one for analog). For instance, this allows you to use 3.3V digital power and 5V for analog power.
