Probe Unit: The main body containing the differential amplifier-Schaltung.
Eingangsklemmen: Connect the test leads to these terminals (red for positive, black for negative).
BNC-Schnittstelle: Connects the probe output to the oscilloscope input.
5MHz Bandwidth Limit Button: (Available on 100MHz-200MHz versions, except DP7000) Limits the bandwidth to 5MHz for noise reduction when measuring lower frequency signals.
Quick Zero Button: Used to quickly zero the probe's output offset.
Dual Range Selection Button: Toggles between different attenuation ranges (e.g., 50X, 500X) to accommodate various input voltage-Ebenen.
Typ-C-Stromeingang: For connecting the USB Type-C power cable.

4. Einrichtungsanweisungen

Stromanschluss: Connect the USB Type-C power cable to the probe unit and the power adapter. Plug the power adapter into a suitable power outlet.
Oscilloscope Connection: Connect the BNC interface of the differential probe to an input channel of your oscilloscope using a BNC cable.
Input Lead Connection: Attach the red and black test leads to the corresponding input terminals on the differential probe. Ensure a secure connection.
Attaching Probes to Circuit: Connect the alligator clips or other appropriate accessories to the test leads. Carefully attach the red clip to the positive test point and the black clip to the negative test point of the circuit under test.
Einschalten: Ensure the oscilloscope is powered on and configured for the appropriate input settings (e.g., 1MΩ input impedance).

5. Bedienungsanleitung

5.1. Einschalten und erste Überprüfung

Once connected, the probe's power indicator LED should illuminate. Before making measurements, perform a quick zero adjustment.

5.2. Quick Zero Adjustment

With the input leads disconnected from any circuit, press the Quick Zero button on the probe unit. This calibrates the probe to output zero volts when no differential voltage is present, ensuring accurate measurements.

5.3. Bereichsauswahl

Der Dual Range Selection button allows you to switch between different attenuation ratios (e.g., 50X, 500X). Select the appropriate range based on the expected voltage of the signal you are measuring. A higher attenuation ratio is used for larger input voltages.

Lower Attenuation (e.g., 50X): For smaller differential voltages, providing higher sensitivity.
Higher Attenuation (e.g., 500X): For larger differential voltages, preventing saturation and ensuring safe operation.

5.4. Bandwidth Limit (Optional)

For models that support it (100MHz-200MHz versions, except DP7000), the 5MHz Bandwidth Limit button can be pressed to reduce the probe's bandwidth to 5MHz. This is useful for reducing high-frequency noise when measuring lower frequency signals, improving signal clarity on the oscilloscope.

5.5. Messungen durchführen

After selecting the appropriate range and performing a quick zero, connect the probe leads to the desired test points on the circuit. Observe the waveform on the oscilloscope. Adjust the oscilloscope's vertical scale and time base as needed to properly display the signal.

6. Wartung

Reinigung: Keep the probe unit and accessories clean. Use a soft, dry cloth to wipe surfaces. Do not use abrasive cleaners or solvents.
Lagerung: Store the probe in a dry, dust-free environment when not in use. Protect the BNC connector and input terminals from damage.
Kabelpflege: Avoid sharp bends or kinks in the cables. Inspect cables regularly for signs of wear or damage.
Kalibrierung: While the Quick Zero function provides on-demand calibration, periodic professional calibration may be required for applications demanding the highest accuracy. Refer to Micsig's official support for calibration services.

7. Fehlerbehebung

Problem	Mögliche Ursache	Lösung
Kein Signal am Oszilloskop	Probe not powered on. Incorrect BNC connection. Oscilloscope input settings incorrect. Probe leads not properly connected to circuit.	Check power indicator LED and power supply. Ensure BNC cable is securely connected to both probe and oscilloscope. Verify oscilloscope channel is enabled and input impedance is 1MΩ. Ensure test leads are firmly attached to the probe and the circuit.
Noisy or unstable signal	Incorrect range selected. External electromagnetic interference. Probe not properly zeroed.	Select a higher attenuation range if the signal is too large, or a lower range for better sensitivity. Ensure proper grounding and minimize proximity to strong electromagnetic fields. Perform a Quick Zero adjustment. Consider using the 5MHz bandwidth limit if available and appropriate for the signal frequency.
Probe power LED off	Stromkabel nicht angeschlossen oder defekt. Netzteil defekt.	Check USB Type-C cable connection and try a different cable. Try a different power adapter or USB power source.
