3. Initial Setup
- Power Connection: Connect the provided power cord to the AC input on the rear panel of the oscilloscope and then to a suitable AC power outlet. Ensure the voltage matches the oscilloscope's requirements (100-240V AC, 45-440Hz).
- Probe Connection: Connect the oscilloscope probes to the BNC input connectors (CH1 and CH2) on the front panel. Ensure a secure connection by twisting the probe connector clockwise until it locks.
- Probe Compensation: Before taking measurements, compensate the probes to ensure accurate readings. Connect the probe to CH1 and attach the probe tip to the probe compensation test signal output (usually a square wave). Adjust the compensation screw on the probe until a flat-top square wave is displayed on the screen. Repeat for CH2.
- Power On: Press the power button located on the front panel to turn on the oscilloscope.

- Storage: Store the oscilloscope in a dry, dust-free environment when not in use.
- Safety: Do not open the instrument casing. Hazardous voltages are present inside. Refer all servicing to qualified personnel. Ensure adequate ventilation during operation.
8. Troubleshooting
If you encounter issues with your Hantek DSO5072P, refer to the following common problems and solutions:
- No Power: Check the power cord connection and the power outlet. Ensure the power button is pressed.
- No Waveform Display: Verify that the probe is correctly connected to both the oscilloscope and the circuit under test. Adjust the Volts/Div and Sec/Div settings. Ensure the trigger level is set appropriately.
- Unstable Waveform: Adjust the trigger level and trigger mode. Check the probe compensation.
- Incorrect Measurements: Ensure probes are properly compensated. Verify the measurement settings.
For persistent issues, consult the full user manual on the software CD or contact Hantek support.
