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.
