DESCRIPTION
This 1,000 A AC clamp can be used for easy display and measurement
of current curves. Equipped with a coaxial cable terminated by a BNC
connector, it is ideal for use with any oscilloscope. It outputs a signal in
mV directly proportional to the current. It offers 3 different sensitivities.
