OWON HDS160 Oscilloscope Multimeter: Unboxing, Review, and Teardown

The article presents a hands-on unboxing, review, and teardown of the OWON HDS160, a 4½-digit handheld oscilloscope multimeter purchased for 365 RMB. Its main appeal is the built-in 1 MHz oscilloscope that works with standard multimeter test leads, enabling direct voltage or current waveform measurement and automatic detection of the input jack to switch ranges. Key specifications include 60000-count display, DC voltage accuracy of ±(0.05%+5 digits), CAT III 1000 V safety rating, 2.8-inch IPS screen, and a single 18650 battery. Field tests cover USB voltage, AC mains waveform (50 Hz, 328 V peak, 232 V RMS), STM32 board inrush current, and low-power current measurements. The teardown reveals an HC32F460PETB MCU, HY3131 multimeter front-end, MAX6006AESA voltage reference, SGM41511 charger, GD25Q128ESIG flash memory, and infrared components for jack detection. The author notes a slightly crooked Type-C port and a clock that resets when the battery is removed. Readers gain insight into the device’s capabilities, component choices, internal construction, and practical limitations, useful for evaluating its suitability for low-frequency electrical and embedded debugging tasks.
