१.६। प्रयोगकर्ता सुझावहरू
- Auto-Range for Quick Setup: When starting a new measurement, especially with unknown signals, utilize the 'AUTO RANGE' function in oscilloscope mode for a quick and optimal display.
- Afterglow Mode for Intermittent Signals: If you are trying to capture transient or intermittent events, enable the 'Afterglow Mode' with a longer duration (e.g., 1S or Unlimited) to observe signal history.
- जाँच क्षतिपूर्ति: Regularly check and adjust probe compensation (using the dedicated output, 9 in Figure 4) to ensure accurate oscilloscope measurements.
- USB-C for Data Logging: For long-term monitoring or detailed analysis, connect the device to a computer via the USB Type-C port to export and log waveform data.
T. समस्या निवारण
- उपकरण सक्रिय हुँदैन: Ensure the battery is charged. Connect the USB-C cable to a power source and allow it to charge for some time. Check the power switch (5 in Figure 4).
- No waveform displayed in Oscilloscope mode: Check probe connections to CH1/CH2. Ensure the signal source is active. Try using the 'AUTO RANGE' function. Verify trigger settings are appropriate for the signal.
- Incorrect readings in Multimeter mode: Ensure test leads are connected to the correct input terminals (A, mA, VΩHz, COM) for the desired measurement. Check the selected measurement function.
- Signal Generator not outputting: Verify the output cable is connected to GEN Out (7 in Figure 4). Ensure the signal generator is enabled and configured with desired waveform, frequency, and ampलिटुड।
- स्क्रिन स्थिर छ: Try pressing the 'SAVE HOLD' button (11 in Figure 4) to see if it's in data hold mode. If not, power cycle the device.
