Frequently Asked Questions
1. Q: When measuring slow signals, I experience waveform instability and trigger failure. How can I improve this?
A: The methods are as follows:
1. Adjust the trigger level: Set the level to the middle of the signal amplitude (approximately 50%) to avoid noise interference.
2. Switch the trigger edge: Press and hold the MODE key to select "Falling Edge." This can sometimes make it easier to trigger on high-slope signals.
3 Use Single Mode: Short-press the MODE key to switch to Single mode, which is suitable for capturing non-periodic signals.
4. Reduce the sampling rate: Slowing the timebase (e.g., 500μs/div) can extend the observation time and display the complete waveform.
2. Q: My oscilloscope isn't accurately displaying a sine wave, or the waveform is abnormal. How can I improve this?
A: Here are the steps:
1. Confirm that the input frequency is within the range (≤40 kHz is recommended).
2. Set the probe magnification and synchronize the device settings (probe to 1X, device to 1X).
3. Adjust the coupling mode to DC or AC to match the signal type.
4. If the abnormality persists: Check the probe and signal source.
3. Q: What should I do if the oscilloscope won't turn on or off, won't read, or freezes?
A: Troubleshooting steps are as follows:
1. Check the battery level and, if necessary, recharge and restart.
2. Use a toothpick or other similar tool to gently press the reset button and try restarting. If this doesn't work, try reflashing the firmware.
3. Check the connector for damage, looseness, or foreign objects, and confirm that the signal frequency is within the specified range (≤200kHz).
Tips:
Avoid measuring high voltage at 1X, use the correct plug, and avoid rough handling to reduce malfunctions.
4. Q: What should I do if the device does not work as expected (e.g., the amplifier cannot be adjusted, or the display lines keep jumping)?
A: Try the following steps to troubleshoot:
1.Check the probe connection: Make sure the probe (e.g., BNC connector) is firmly plugged in and locked, and the ground clip is securely attached to the exposed metal ground of the test device.
2.Confirm signal frequency and settings: If the signal frequency is below 40 Hz, switch the trigger mode to Normal to improve stability for low-frequency signals.
3.Recalibrate and reconnect: Disconnect any unnecessary external cables to avoid interference, press and hold the AUTO button for automatic calibration, then reconnect the signal.
