5.2 Erstes Einschalten

Press and hold the Power On/Off button to turn on the device. The device will typically start in the last used mode. You can change the language and other system settings via the 'System' button.

6. Bedienung des Oszilloskops

The oscilloscope function allows for visualization and analysis of electrical signals over time.

6.1 Anschluss der Sonden

• Connect the oscilloscope probe(s) to the BNC input connector(s) on the top of the device.
• Ensure the probe's ground clip is securely connected to the circuit's ground.
• Connect the probe tip to the test point of the signal you wish to measure.

6.2 Grundlegende Messung

• Press the 'Mode' button to select the Oscilloscope function.
• Press the 'Auto' button. The device will automatically adjust the vertical and horizontal scales and trigger settings to display a stable waveform.
• Use the 'HOR' button and arrow keys to adjust the horizontal time base.
• Use the 'CH1/2' button (if applicable) and arrow keys to adjust the vertical scale (Volts/Div) for each channel.
• The 'Trig/Δ' button allows access to trigger settings for stable waveform capture.

6.3 Automatic Measurements and Cursor Test

The HDS25 supports 7 types of automatic measurements (e.g., Vpp, Vmax, Vmin, Freq, Period) and cursor tests for precise voltage and time readings on the waveform.
