5.2 Connecting the Probe

Connect the oscilloscope probe to the BNC connector on the device. Ensure a secure connection. Select the appropriate attenuation (×1 or ×10) on the probe based on your measurement requirements.

5.3 Powering On/Off

Press and hold the power button (usually marked with a power symbol) to turn the device on or off.

6. Operating Instructions

The OT5 oscilloscope features intuitive controls for easy operation. The 'Function Wheel' and dedicated buttons allow for quick adjustments and menu navigation.

6.1 Basic Measurement

Upon powering on, the oscilloscope will typically enter auto-ranging mode, automatically adjusting vertical and horizontal scales to display a stable waveform. Connect the probe to the circuit under test.

6.2 Adjusting Settings

• Vertical Sensitivity (VOL): Use the 'VOL' buttons or function wheel to adjust the vertical scale (Volts per division).
• Horizontal Time Base (TIME): Use the 'TIME' buttons or function wheel to adjust the horizontal scale (seconds per division).
• Trigger Mode (TRIG): Select between Auto, Normal, and Single trigger modes using the 'TRIG' button. Auto mode is suitable for most general-purpose measurements.
• Cursor (CURSOR): Activate cursors for precise voltage and time measurements.
• Save (SAVE): Save waveform data or screenshots.
• Auto (AUTO): Automatically adjusts the vertical and horizontal scales for optimal waveform display.

6.3 Language Switching

The device supports switching between Chinese and English. Navigate through the menu settings to find the language option and select your preferred language.
