5.2.1 Waveform Analysis

The oscilloscope supports waveform pause, zoom, and movement for detailed analysis of signals. This helps in identifying hidden noise or complex modulation patterns.

Figure 11: Waveform Manipulation

• After pausing to measure waveforms: Set the wheel to voltage and press the Up/Down key to enlarge or reduce vertical sensitivity.
• After pausing to measure waveforms: Set the wheel to time base and press the Up/Down key to reduce the time base.

5.2.2 Trigger Level Adjustment

Adjust the trigger level to stabilize the waveform display. Use the wheel button to change the trigger level.

5.2.3 Persistence Function

The persistence function allows you to observe transient phenomena by displaying previous waveforms. Options include Off, 500ms, 1s, and infinite persistence.

• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in use for extended periods.
• Firmware Upgrade: The device supports firmware upgrades via its Type-C port. Check the official FNIRSI website for the latest firmware and instructions.

9. Troubleshooting

If you encounter any issues with your FNIRSI oscilloscope, please refer to the following common solutions:

• Device not powering on: Ensure the battery is charged. Connect the device to a 5V/1A charger and check the charging indicator.
• No waveform displayed: Check probe connections. Ensure the probe is correctly connected to the 'DSO' input. Use the 'AUTO' button for automatic waveform detection and scaling.
• Unstable waveform: Adjust the trigger level using the wheel button. Ensure the trigger mode is set appropriately (Auto/Normal/Single).
• Screen frozen or unresponsive: Try pressing the power button for a long time to force a restart. If the issue persists, use a small pin to press the reset hole (located near the Type-C port).
• Incorrect measurements: Perform a 1KHz square wave calibration if available on your model. Ensure the probe attenuation setting (X1/X10) matches the physical probe setting.

10. User Tips

• Maximum Voltage: Always be mindful of the maximum input voltage. The device supports up to ±40V (Vpp:80V) with X1 probe setting and up to ±400V (Vpp:800V) with X10 probe setting. Exceeding these limits can damage the device.
• Automotive Use: The oscilloscope is suitable for automotive diagnostics, such as checking sensor signals, ignition patterns, and other electrical components in motorcycles and cars.
• Probe Selection: For higher voltages, always use the P6100 High Voltage Probe with the X10 setting to ensure safety and accurate readings.
• Screen Protection: While the device is robust, consider using a screen protector to prevent scratches during field use.
