Fluke

Which Fluke multimeter suits your use?

When choosing a multimeter, first define which quantities and in what environment will be measured. The most common measurements are voltage, current, resistance, continuity and frequency. For professional use, also consider True RMS measurement, the meter's accuracy and the safety rating required by the electrical environment.

What does the CAT rating mean in a multimeter?

The CAT rating indicates the type of electrical measurement environment the instrument is designed for. Therefore you should not rely solely on the maximum voltage reading when selecting a meter; both the CAT rating and the nominal voltage must match the measurement application. When performing measurements related to electrical installations, always follow appropriate safety instructions and qualification requirements.
