Micsig High Voltage Differential Probe User Manual
Models: DP10007 / DP10013 / DP20003
Introduction
Micsig DP series differential probes convert high voltage differential signals into low-voltage single-ended signals for display on an oscilloscope. Available with low and high attenuation options, these probes can measure differential voltages up to 700V/1300V/5600V.

Making Measurements
- Powering the probe: Connect the probe's USB input to the USB port of the oscilloscope or a suitable USB power source.
- Connecting the probe to the oscilloscope: Connect the probe output BNC to the oscilloscope channel input. Note: make sure the oscilloscope is properly grounded if necessary.
- Set the appropriate attenuation range according to the measured voltage.
- Connecting the input to the device under test: Using the appropriate input accessory, connect the probe to the device under test to start the measurement. If the attenuation range indicator flashes (indicating over-range), please immediately disconnect the power and input.
- Set the measuring instrument.
Best Practices
- Twisting the input leads together can help reduce noise and improve the probe's high frequency response when measuring signals. A diagram illustrates this practice.
- Extending the input leads may introduce more noise. If extension leads are necessary, ensure they are of equal length and the input signal frequency is under 10MHz to avoid measurement errors.
- When measuring a high frequency signal, avoid touching the input lead with your hand or other objects to maintain measurement accuracy.
- Ensure the oscilloscope used has an input impedance of at least 1MΩ and a bandwidth of at least 100MHz.
- Turn on the oscilloscope or externally powered instrument and allow the probe and equipment to warm up for 20 minutes.
- If the probe's zero point accuracy is affected by substantial temperature changes or other circumstances, calibration is needed. To calibrate, short the probe's input terminals, power the probe, and simultaneously press the Attenuation Range Buttons/Indicators for three seconds.
Warranty
Micsig warrants that this probe will be free from defects in materials and workmanship for a period of one (1) year. Accessories are covered for six (6) months from the date of shipment. If a product proves defective during the warranty period, Micsig will, at its option, repair the defective product free of charge for parts and labor, or provide a replacement.
