Notice

The bandwidth of the 1X probe is 5 MHz, and the bandwidth of the 10X probe is 100 MHz. For measurements above 5 MHz, the probe switch must be set to 10X, and the oscilloscope must be set to 10X. Failure to do so will result in significant signal attenuation. The oscilloscope's own probe cable has a capacitance of 100-300 pF, which is substantial for high-frequency signals. The signal is considerably attenuated by the probe before reaching the oscilloscope's input, resulting in an equivalent bandwidth of 5 MHz. Therefore, to match the hundreds of pF of the probe cable, the input is attenuated tenfold (switch in 10X range). A few hundred pF capacitors are used solely for impedance matching. At this point, the bandwidth is 100 MHz. Note that only probes with a bandwidth of 100 MHz or higher can be used.

• Voltage Reading is 0: Adjust vertical sensitivity and time base. Use [AUTOSET] to display a clear waveform.
• Frequency Reading is 0: Ensure the trigger mode is set to Auto. If it remains 0, use [AUTOSET].
• Cycle Reading is 0: Ensure the trigger mode is set to Auto. Adjust the trigger to be within the waveform.
• AC and DC Waveforms are the Same: This can occur with symmetric AC signals or when AC/DC coupling is switched.
• Waveform Jittering: Set the trigger mode to Auto and use [AUTOSET]. Check probe grounding and connection.
• Unstable Waveform: Adjust the trigger voltage. Ensure the signal is properly grounded.
• Cannot Detect Pulse or Digital Logic Signals: Set the trigger mode to Normal or Single, and adjust trigger voltage, time base, and vertical sensitivity.
• No Waveform for Battery or DC Voltage: In DC link mode, adjust vertical sensitivity to display a straight line.
• Charging Issues: Use a 5V 2A charger. Laptop USB ports may provide insufficient power.
• Static Waveform at 50Hz: This is normal for 50Hz signals; the oscilloscope adjusts sampling rate accordingly.
• VPP Reading Lower Than Expected: The displayed value might be RMS. Check the parameter display for RMS voltage.
• Distorted AC Waveform: Household power grids often have harmonics that cause distortion, which is normal.

• Signal Attenuation Above 5 MHz: Ensure the probe and oscilloscope are set to 10X for measurements above 5 MHz.
• Green Charging Light Not On: The light indicates charging is in progress. If the battery icon is full, the battery is fully charged.
