4. Setup
Follow these steps to set up your Micsig MDP3001 probe for measurement:
- Connect to Oscilloscope: Connect the BNC output of the MDP3001 probe to an input channel of your oscilloscope using a standard BNC cable.
- Power the Probe: Connect the USB power cable to the MDP3001 probe and to a 5V USB power source (e.g., oscilloscope USB port, computer USB port, or USB power adapter). The probe requires external power to operate.
- Attach Test Leads: Connect the red and black test leads to the input terminals of the MDP3001 probe. Ensure a secure connection.
- Attach Alligator Clips: If needed, attach the red and black alligator clips to the ends of the test leads for easier connection to the circuit under test.

5. Operating Instructions
Once the probe is set up, follow these steps for accurate measurements:
- Power On: Ensure the probe is powered via USB and the oscilloscope is turned on.
- Select Range: The MDP3001 features dual range selection. Choose the appropriate range based on the expected voltage of the signal you are measuring. Refer to the probe's label or specifications for range details.
- Quick Zero Adjustment: Before connecting to the circuit, short the red and black input leads together. Press the "Quick Zero" button on the probe (if available, or follow oscilloscope's zeroing procedure) to eliminate any offset voltage. This ensures accurate differential measurements.
- Connect to Circuit: Carefully connect the red and black test leads (or alligator clips) to the two points in the circuit where you wish to measure the differential voltage. Ensure secure and safe connections, especially with high voltages.
- Oscilloscope Settings: Adjust your oscilloscope's vertical scale (Volts/Div) and horizontal scale (Sec/Div) to properly display the waveform. Remember to account for the probe's attenuation ratio when interpreting the displayed voltage.

6. Maintenance
Proper maintenance ensures the longevity and accuracy of your MDP3001 probe.
- Cleaning: Use a soft, dry cloth to clean the probe and cables. Do not use abrasive cleaners or solvents. Ensure the probe is disconnected from all power sources before cleaning.
- Storage: Store the probe and its accessories in a clean, dry, and dust-free environment when not in use. Avoid extreme temperatures and humidity.
- Cable Care: Avoid sharp bends or kinks in the cables. Do not pull on the cables to disconnect them; always grasp the connector.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal on oscilloscope | Probe not powered; incorrect oscilloscope input selection; faulty cable connection; probe damaged. | Ensure USB power is connected and active. Verify oscilloscope input channel is selected. Check all BNC and test lead connections. Inspect probe for damage. |
| Incorrect voltage reading | Wrong attenuation setting on oscilloscope; incorrect probe range selected; offset not zeroed. | Adjust oscilloscope's vertical scale to match probe's attenuation. Select the appropriate range on the probe. Perform a Quick Zero adjustment. |
| Noisy or distorted waveform | Poor grounding; electromagnetic interference; damaged probe or cables. | Ensure proper grounding of all equipment. Minimize external interference. Inspect probe and cables for damage. |
