1. Summary
CP9000（S/L）Series are AC Flexible Current Probe .It has the advantages of
high bandwidth, high precision (typically 1%) characteristics. The frequency can be from
several Hz to tens of MHz, current ranges from mA level to kA level, which solves the
problem of current test.
The main features include:
easy to measure with thin ,flexible ,clip-around coil; Non-intrusive-loading the circuit under
test by only a few pH;
BNC Output: easy to plug directly in scope, data acquisition equipment, DVM or power
recorders;
USB interface Power Supply ，ease and flexibility to use;
Sound and LED alarm function, the design is more humanized；
Can be customized according to customer requirements, meet the test requirements
of special applications.
CP9000S Series: Has an extremely thin, clip-around Rogowski coil of typically 1.6mm
cross-section. Such a thin coil enables currents to be measured in the most difficult to
reach parts of a power Electronic converter with negligible disruption to the circuit
under test. It can be used in MOSFET or IGBT devices as small as TO-220 or TO-47. Cross
section only 4mm for 2kV isolation. Accuracy is ±2% of reading.
CP9000 Series probe: Cross section only 3.8mm typically, Safe Coil Voltage Isolation
2kVpk，Accuracy of ±2% of reading. It is ideal for monitoring currents in even the most
difficult to reach parts of a circuit.
CP900L Series probe: Cross section only 8mm typically, Safe Coil Voltage Isolation
10kVpk，Accuracy of ±1% of reading. It is ideal for power electronics development work
because it combines an easy to use thin, flexible, clip-around coil with an ability to
accurately replicate fast switching current waveforms be they sinusoidal, quasi-sinusoidal or
pulsed.
