True RMS method 3280
-20
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.
MEAN value method 3280-10
●Crest factor: 2.5 max.
(
Applies to input of at least 60% of the range.)
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.
WARNING
Includes TEST LEAD 9208 and CARRYING CASE 9398
●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
True RMS
In order to prevent short-circuits and injury, use the clamp product on electrical
circuits with a voltage less than the maximum operation circuit oltage.
