3.2 Charging the Device

The 5012H oscilloscope is equipped with a built-in 3000mAh rechargeable lithium battery. For first-time use, it is recommended to fully charge the device.

1. Connect the provided USB charging cable to the USB port on the oscilloscope.
2. Connect the other end of the USB cable to a standard USB power adapter (not included) or a computer's USB port.
3. The charging indicator on the device will illuminate. Charging typically takes several hours.
4. A full charge provides approximately 8 hours of continuous operation.

3.3 Attaching the Probe

To measure signals, you need to attach the oscilloscope probe:

1. Locate the BNC connector on the top of the oscilloscope.
2. Align the probe's BNC connector with the oscilloscope's BNC input.
3. Push the probe onto the connector and twist clockwise until it locks securely.
4. Ensure the probe's ground clip is connected to the circuit's ground point during measurements.
5. Set the probe's attenuation switch (1X or 10X) according to your measurement needs. Remember to adjust the oscilloscope's settings to match the probe's attenuation for accurate readings.

4. Operating Instructions

4.2 Waveform Acquisition

To begin measuring a signal:

1. Ensure the probe is correctly attached and connected to the circuit under test.
2. Power on the oscilloscope by pressing and holding the power button.
3. Press the AUTO button. The oscilloscope will automatically adjust the vertical scale, horizontal time base, and trigger settings to display a stable waveform.
4. If further adjustments are needed, use the navigation buttons (▲/▼ and ◀/▶) to modify the vertical sensitivity (Volts/div) and horizontal time base (Time/div).
5. Use the TRIG button and navigation keys to fine-tune the trigger level for stable waveform capture.
6. Press the EDGE button to switch between rising edge and falling edge triggering, depending on your signal.
