The OWON HDS120 oscilloscope multimeter series brings two commonly used electrical test functions together in one instrument: multimeter measurement and oscilloscope waveform observation. This approach can be useful when a task requires both numerical readings and a view of signal behavior, without changing between separate devices.
According to OWON, the HDS120 series is designed around a 4½-digit, 20,000-count display and supports measurements including voltage, current, resistance, capacitance, and diode testing. It also provides automated waveform measurements for users who need to assess key signal values directly on the instrument.
Combined measurement and waveform functions
A conventional multimeter is well suited to checking a measured value, while an oscilloscope adds a visual representation of a changing electrical signal. The HDS120 series combines these roles. This can help technicians and electronics professionals move from a basic measurement to waveform inspection within the same workflow.
For multimeter operation, the series supports voltage, current, resistance, capacitance, and diode tests. These functions address a range of routine electrical and electronic measurement needs. The 4½-digit format and 20,000-count display provide the stated measurement resolution for viewing readings on the device.
Automatic waveform measurements
When examining a waveform, it is often necessary to identify more than its general shape. The OWON HDS120 series includes automatic measurements for Vmax, Vmin, Vp-p, Vavg, Vrms, and Hz. These parameters cover maximum voltage, minimum voltage, peak-to-peak voltage, average voltage, root mean square voltage, and frequency.
Having these values available as automatic waveform measurements can make signal evaluation more direct. For example, users can compare maximum and minimum voltage levels, check the signal span through Vp-p, review average or RMS values, and identify frequency. The suitability of a specific measurement should still be assessed against the circuit and task being tested.
Smart probe detection and button-based operation
The HDS120 series features smart probe detection. OWON states that the instrument can automatically switch measurement values according to the probe insertion position. This design is intended to simplify setup and help reduce the risk of incorrect operation that could damage the instrument.
Its all-button design is another practical detail. Physical controls can offer a straightforward operating method during test work, particularly where users need to make repeated adjustments or work through measurement functions in an orderly sequence. The stated design also emphasizes device durability.
Display and portable power arrangement
For viewing measurement results and waveforms, the HDS120 uses a 2.8-inch IPS display. OWON describes the screen as high-definition and specifies a high-brightness, high-contrast dual-theme display mode. The aim is clear visibility in both strong and dark lighting conditions.
The series uses an 18650 lithium battery system. This rechargeable battery arrangement is intended to support longer periods of use and help maintain continuity during measurement tasks. Actual operating time can depend on how the instrument is used and on the conditions of the measurement session.
High-voltage measurement context
OWON states that the HDS120 series meets CAT III 1000V and supports measurement of high-voltage waveforms up to 1000V. These ratings are important considerations for users working with higher-voltage applications. Measurement work should always follow the applicable instrument instructions, probe requirements, and established electrical safety procedures.
Overall, the OWON HDS120 oscilloscope multimeter is positioned as a compact solution for users who require standard multimeter measurements alongside waveform analysis. Its combination of a 20,000-count display, automatic waveform values, smart probe detection, button operation, IPS screen, and stated CAT III 1000V capability defines the series' core feature set.
