CT4448-100

The CT4448 is rated to 1,000 V CAT II / 600 V CAT III.^a

These attenuators are ideal for lower frequency (<9 kHz) but higher voltage applications where safety calls for more robust probes and leads than standard oscilloscope probes. Using 4 mm DMM probes and/or insulated alligator clips provides a safer, more durable handheld test setup.

The CT4448 provides a 1 MΩ impedance and accepts 4 mm sheathed banana plugs allowing for work in higher voltages and CAT environments such as electrical panel mains.

Selecting an adapter with the appropriate attenuation factor can reduce the input voltage to the range for your application and equipment. This is especially critical for oscilloscopes with a low input voltage such as portable USB or wireless types.
