The Smarter Way to Carry Two Instruments
Most technicians carry a multimeter every day and reach for an oscilloscope when things get tricky. The ANENG AOS02 eliminates that choice — one MODE button press toggles between a fully functional true-RMS multimeter and a digital storage oscilloscope, with no probe swapping or reconfiguration required.
Oscilloscope That Punches at Its Price
At 48MSa/s with 64Kpts of storage depth, the AOS02 comfortably handles audio circuits, power supplies, sensor outputs, and low-frequency digital signals. The one-key AUTO function locks onto an unknown waveform in seconds. Three trigger modes (Auto, Normal, Single) cover everything from continuous monitoring to one-shot transient capture, with rolling mode for slow signals below 100ms/div. Export waveform screenshots to PC via USB for reporting or further analysis.
True-RMS Multimeter with Real Safety Credentials
9,999 counts, CAT III 1000V rated, and protected by dual ceramic fuses (user-replaceable without tools). Measures everything you’d expect from a professional DMM — voltage, current, resistance, capacitance, frequency, diode, continuity — plus temperature via the included thermocouple probe and transistor testing. The NCV detector adds non-contact live wire detection for fast, safe circuit identification.
The 18650 Advantage
Unlike devices with sealed internal batteries, the AOS02 uses a standard 18650 lithium cell. When it eventually wears out, you swap it yourself for a few dollars — not return the device or buy a replacement unit.
Honest Performance Note
Real-world effective oscilloscope bandwidth sits comfortably in the 5–6MHz range for most signal types. For anything above that threshold, consider upgrading to the TOOLTOP ET120MPRO (120MHz) or ZOYI ZT-703S (50MHz dual-channel). For the vast majority of hobbyist and technician tasks — audio, power, sensors, automotive — the AOS02 is more than sufficient and represents exceptional value.
