Prevents
●Independent-opening double-lever design
●Slim body to allow easy clamping
even for narrow conductors
●Eliminates magnetization-induced heat and
noise, even in heavy-current measurement
●No metal (iron core) exposure, ensuring
enhanced safety
The 3280-20 performs accurate measurements of even small
currents in the AC 42.00 A range.
It also guarantees accuracy of True RMS measurements for
frequencies from 40 Hz to 1 kHz.

WARNING 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.
DANGER 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.
