6. Operating Instructions
This section outlines the basic operation of the UNI-T UTD2152CEX oscilloscope.
6.1 Basic Waveform Display
After powering on, connect a probe to an input channel (e.g., CH1) and attach the probe tip to the signal source you wish to observe. Use the AUTO button for quick automatic setup of vertical, horizontal, and trigger settings. Adjust the VERTICAL (Volts/Div) and HORIZONTAL (Sec/Div) knobs to scale the waveform appropriately on the 7-inch display.
