Description
The CT231A, CT235, CT236, CT237, and CT238 current transformers/probes measure AC or AC/DC current. These probes convert high current to a low level millivolt or milliamp signal for input directly into a test instruments. They can be used with standard DMMs, recorders, digital or analog meters, data loggers/DAS, oscilloscopes, or other test and measurement instruments.
The CT238 is for low-current ACor DC clamp to 20A.
