Turn the Volts/Div knob until the waveform fills about 60-80% of the screen height.
Supports automatic measurements for RMS voltage, peak-to-peak, and overshoot, as well as cursor measurements (time, voltage, and auto-cursor). Math Functions:
The leading edge of the square wave spikes upward before flattening out.
The manual is also widely available on third-party documentation sites like manuals.plus and manualslib.com . These archives often have the manual in multiple languages, which can be useful if you are not a native English speaker. hanmatek dos1102 manual

The front panel is divided into distinct, color-coded functional zones: Turn the Volts/Div knob until the waveform fills
The trigger stabilizes repeating waveforms or captures single shot events.
Press to toggle the respective channel waveform on or off, or to open its configuration menu (coupling, probe attenuation, bandwidth limit).
When you unbox your DOS1102, you will find the oscilloscope unit, two 10X/1X passive probes, a power cord, a USB interface cable, and a quick-start leaflet. The manual is also widely available on third-party
Attach the alligator ground clip to the ground terminal right next to the signal terminal. Press the button on the control panel. Inspect the square wave shape on the screen.
Set the physical switch on the probe handle to the position.
