Select the desired measurement type (e.g., Vpp, Frequency, Vmax) using the menu buttons on the right. 4.2 Using Cursors for Precise Measurement Press the button. Set Type to Voltage or Time .
The trigger system tells the oscilloscope exactly when to start drawing the signal. If your waveform is scrolling wildly across the screen, your trigger settings need adjustment.
Before first use, you should connect your probe to the calibration terminal (usually a 1 kHz square wave) and adjust the compensation trimmer until the wave is flat. Measurement Modes:
10K points (Note: This can restrict deep zooming on long captures). 2. Essential Safety Precautions
: Some users feel the manual is too "general" and wish it were more specific about the complex digital features available. Supplemental Needs
Plug in the power cord and press the power button on the top-left panel.
Moves the waveform up or down on the screen graticule. Horizontal Controls

1 MΩ ± 2%, in parallel with 20 pF ± 3 pF Maximum Input Voltage: 400V (PK + DC, Peak) 2. Front Panel Layout and Control Definitions
Triggering is often the most misunderstood concept in oscilloscopes, and the DOS1102 manual provides several modes to stabilize waveforms.
Adjusts the voltage threshold that the signal must cross to trigger a stable display.
Before powering on, the manual recommends proper connection to ensure safety and accuracy:
