Model No. (Order Code)

3287 True RMS

Compact & Easy

The 3287 performs accurate measurements of even small currents in the AC/DC 10.00 A range. In AC mode it also guarantees accuracy of true RMS measurements for frequencies from 10 Hz to 1 kHz. Handles low frequency to distorted currents including higher harmonics, simplifying maintenance of energy-saving equipment up to a maximum of 100 A.
