UNI-T UT81B 2-in-1 Handheld Digital Oscilloscope Multimeter

From the shop's description

UNI-T UT81B 2-in-1 Handheld Digital Oscilloscope Multimeter The UNI-T UT81B 2-in-1 Handheld Digital Oscilloscope Multimeter is a handheld instrument designed to bring waveform observation and conventional electrical measurement together in a single portable unit. Instead of carrying separate tools for basic circuit checks and signal viewing, technicians can move between digital readings and waveform display from the same instrument, making the testing process more convenient during bench work or field service. Its oscilloscope mode is intended for examining changing electrical signals, while the digital multimeter mode supports everyday diagnostic work on electrical and electronic circuits. The instrument is designed to make movement between numerical readings and waveform observation straightforward, helping users study circuit behavior from different perspectives without depending on a full-size bench oscilloscope for every troubleshooting task, all within the same compact handheld working format. Features: 2-in-1 digital oscilloscope and digital multimeter design. Switchable waveform and digital reading modes. Automatic and manual ranging in multimeter mode. Automatic waveform setup. Waveform save and recall function. USB interface with optical isolation. Data Hold function. Relative measurement mode. Automatic power-off function. Low-battery indication. Adjustable LCD backlight. Adjustable display contrast. Selectable trigger modes. Continuity buzzer. Duty-cycle measurement. Replaceable battery access. Built-in tilt stand for convenient viewing. Waveform storage for saved measurements and setups.
