Main features of the CWT standard model:

• Traceable calibration data (including certificate)

• Non-contact measurement has no effect on the circuit under test

• No magnetic material means excellent linearity

• Complete DC current isolation; can measure small ripple currents on large DC currents

•  Exceeding the current range will not cause damage(not exceeding the absolute maximum di/dt)
