CT Series Current Clamps
A comprehensive line of transformers/probes for AC or AC/DC current measuring adds to the list of Wavetek Meterman products for electrical measurement applications. Use these "CTs" as an accessory front-end to standard DMMs, recorders, digital or analog meters, data loggers/DAS, O'Scopes, or other test and measurement instruments to increase current measuring capability. These probes convert high current to a low level millivolt or milliamp signal for input directly to test instruments.
