- 1KHz/3V Square Wave Output: A dedicated output for calibration or testing.
Operating the Oscilloscope
Basic Oscilloscope Operation
- Power On: Long press the power button.
- Connect Probe: Attach the oscilloscope probe to the BNC input connector. Ensure the probe is securely connected.
- Probe Attenuation Setting: Set the probe's attenuation switch (e.g., X1 or X10) to match the setting on the oscilloscope's display. The HO15 supports voltage measurements up to ±400V with dual probes (X1/X10).
- Connect to Circuit: Connect the probe tip to the test point on your circuit and the ground clip to the circuit's ground.
- Auto-Adjust: Press the AUTO button to automatically adjust the vertical and horizontal scales for a stable waveform display.
- Manual Adjustments: Use the Function Wheel to fine-tune vertical sensitivity (Volts/Div), horizontal time base (Time/Div), and trigger level.
- Trigger Modes: The HO15 features Auto, Normal, and Single trigger modes. These are crucial for stable signal acquisition, especially for intermittent or complex signals.

Signal Generator Function
The HO15 includes a built-in signal generator capable of outputting various waveforms. This feature is useful for testing circuits or calibrating other equipment.
- Waveform Selection: Press the Function Wheel to enter the signal generator menu. Rotate the wheel to select from available waveforms.
- Adjust Parameters: Adjust the frequency, amplitude, and duty cycle (for some waveforms) using the Function Wheel.
- Available Waveforms: The HO15 supports Square, Sine, Triangle, Half, Full, and Sawtooth waveforms.

Saving Waveforms
To save the current waveform display as an image, long press the SAVE button. The image will be stored internally and can be accessed later or transferred via the USB-C port.
Maintenance
Proper maintenance ensures the longevity and accuracy of your HANMATEK HO15 oscilloscope.
- Cleaning: Use a soft, dry cloth to clean the device. For stubborn dirt, a slightly damp cloth with mild detergent can be used, but ensure no liquid enters the device. Do not use abrasive cleaners or solvents.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. If storing the device for an extended period, charge it to approximately 50% and recharge every few months.
- Storage: Store the oscilloscope in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. Use the provided protective carrying case when transporting the device.
- Probe Care: Handle probes carefully. Avoid bending or stressing the cables. Clean probe tips as needed.
Troubleshooting
This section addresses common issues you might encounter with your HO15 oscilloscope.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Connect the device to a USB-C charger and allow it to charge for at least 30 minutes before attempting to power on again. |
| No waveform displayed. | Probe not connected or faulty; incorrect vertical/horizontal settings; no signal input. | Ensure the probe is securely connected. Press the AUTO button. Verify the probe is connected to a live signal source. Check probe attenuation settings. |
| Unstable or noisy waveform. | Incorrect trigger settings; poor ground connection; external interference. | Adjust trigger level and mode. Ensure the probe's ground clip is securely connected to the circuit's ground. Minimize electromagnetic interference. |
| Signal generator not outputting. | Incorrect settings; cable not connected. | Verify waveform type and parameters are set correctly. Ensure a cable is connected to the signal generator output. |
