The 3287, which can handle even cogenerator /
inverter energy-saving equipment:
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.

Inspect the unit and check that it is operating correctly before use. When carrying out measurement on live lines, wear
proper protective gear, insulating rubber gloves, insulating rubber boots and safety helmet, and use extreme caution to
avoid electric shock accidents.In order to prevent short-circuits and injury, use the clamp product on electrical circuits
with a voltage less than the maximum operation circuit voltage.
