Product Usage Instructions

Dual Range Selection:
The CP1003B/CP503B current probe features a dual-range selection for easy measurement of low current values. Make sure to select the appropriate range based on the current being measured.

Degaussing and Automatic Zero Setting:
To ensure accurate measurements, perform degaussing and automatic zero settings as per the user manual instructions before taking measurements with the probe.

BNC Interface Compatibility:
The standard BNC interface of CP1003B/CP503B makes it suitable for use with all oscilloscopes. Connect the probe securely to the oscilloscope using the BNC interface for reliable measurements.

Applications:
The CP1003B/CP503B current probe is ideal for various applications including electric vehicle transportation design, switching power supply design, semiconductor devices design, avionics design, and more. Refer to the user manual for specific guidance on using the probe for different applications.

FAQ:

  • Q: What is the maximum frequency range that the CP1003B/CP503B can measure?
    A: The CP1003B has a bandwidth of 100MHz, while the CP503B has a bandwidth of 50MHz. Both probes can easily measure signals over 20MHz.

  • Q: How do I know if the input current exceeds the probe’s maximum range?
    A: The overload indicator on the probe will flash when the input current exceeds the maximum range, alerting you to adjust the range selection or reduce the input current.
