Turn the knob until the horizontal trigger line intersects your waveform on the screen. The signal will instantly lock into place and stop drifting. Using Automatic Measurements
According to the manufacturer's listing, when you unbox your DOS1102, you should find:
) to fully understand features like FFT analysis or PC software communication. Software Setup
Connect the probe tip to the (the small metal tab on the bottom right of the front panel, usually marked as ~5V @ 1kHz).
Press the power switch. The device will perform a self-check. hanmatek dos1102 manual
The scope waits for a single trigger event, captures it, and freezes the display ( STOP ). This is perfect for capturing power-on inrush current or single digital data packets. How to set up a basic Edge Trigger: Press the Trigger Menu button. Set Type to Edge .
Follow these steps to safely capture a clean, readable signal. Step-by-Step Signal Capture
Vpp (Peak-to-Peak), Vmax, Vmin, Vtop, Vbase, Vavg, and RMS voltage.
You can perform operations like , CH1 - CH2 , or CH1 × CH2 . Turn the knob until the horizontal trigger line
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.
Press the menu button and ensure the probe attenuation setting in the digital menu matches the physical switch ( 10X ).
Press to toggle the corresponding channel on or off on the screen. Pressing these buttons also opens the channel menu on the display.
Probes must be matched to the oscilloscope channel to ensure accurate signal measurements. Incorrectly compensated probes introduce severe measurement errors. Software Setup Connect the probe tip to the
The 7-inch screen displays the waveform grid (graticule), status bars, and current measurement parameters.
Instantly sets the trigger level to the exact midpoint of the signal's peak-to-peak amplitude.
Turn the trimmer tool in the opposite direction until the wave loses its rounded slopes.
The official user manual is the most important companion to your device. Here is exactly where to find it online to ensure you always have the most accurate information.
The screen will display the absolute positions of both cursors alongside (voltage difference) or Δcap delta T (time difference / frequency equivalence). Advanced Functions: Math, FFT, and Storage Waveform Math & FFT
