5. Opsætning

1. Strømtilslutning: Connect the provided USB charger and cable to the device's power input port. Plug the charger into a suitable power outlet.
2. Tænd: Press the 'POWER' button located on the front panel to turn on the device.
3. Probeforbindelse: For oscilloscope measurements, connect the 100MHz probes to the CH1 and CH2 BNC input connectors. Ensure the probes are securely twisted into place.
4. Probekompensation: Before taking measurements, it is recommended to compensate the probes. Connect the probe tip to the probe compensation output (usually a square wave signal on the device) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.

6. Grundlæggende betjening

6.1 Oscilloskoptilstand

The FNIRSI-1014D operates primarily as a dual-channel digital oscilloscope. The main display shows the waveforms, measurement parameters, and control settings.

Figure 5: The oscilloscope display showing various menu options for settings like coupling, scale, and trigger.

• Vertikale kontroller: Use the CH1/CH2 buttons and associated rotary encoders to adjust vertical position and voltage scale (Volts/Div) for each channel.
• Horisontale kontroller: Use the TIME/DIV rotary encoder to adjust the horizontal time base.
• Triggerindstillinger: The 'EDGE' button allows selection of rising or falling edge trigger. 'MODE' button selects trigger mode (Auto, Normal, Single).
• AUTO knap: Pressing the 'AUTO' button automatically adjusts the vertical and horizontal settings to display a stable waveform.
• Målefunktioner: The device supports various automatic measurements. Refer to the on-screen menu for available parameters.

6.2 Signalgeneratortilstand

The FNIRSI-1014D includes a built-in 10MHz DDS signal generator capable of producing 14 types of waveforms.

• Activating Generator: Press the 'GEN' button to access the signal generator functions.
• Valg af bølgeform: Use the navigation buttons to select the desired waveform type (e.g., Sine, Square, Triangle).
• Frekvens/AmpLysjustering: Use the rotary encoders to set the frequency and amplitude of the generated signal.
• Udgangsforbindelse: Connect the signal generator output (typically a dedicated BNC port or shared with CH2 in generator mode) to the circuit or device under test.

7. Vedligeholdelse

• Rensning: Use a soft, dry cloth to clean the device's exterior. For stubborn dirt, a slightly damp en klud med et mildt rengøringsmiddel kan bruges, så det sikres, at der ikke kommer væske ind i enheden.
• Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer, når den ikke er i brug.
• Probepleje: Handle probes carefully. Avoid bending or stressing the cables. Keep probe tips clean.
• Batteri (hvis relevant): If the device has an internal rechargeable battery, follow manufacturer guidelines for charging and storage to prolong battery life.

8. Fejlfinding

• Ingen strøm:
  • Ensure the power adapter is correctly connected and the power outlet is functional.
  • Kontroller, at tænd/sluk-knappen er korrekt aktiveret.
• Ingen bølgeformvisning:
  • Verify probes are correctly connected to the input channels and the signal source.
  • Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Check trigger settings (Mode, Level, Edge). Try pressing the 'AUTO' button.
  • Ensure the input coupling (AC/DC) is appropriate for the signal.
• Forvrænget bølgeform:
  • Perform probe compensation.
  • Check for proper grounding of the device and the circuit under test.
  • Ensure the signal amplitude does not exceed the input range of the oscilloscope.
