   FLUKE 381   Description / Specification:    
FLUKE 381 2500 Amp AC/DC True RMS Clamp Meter

The Fluke 381 Clamp Meter with a detachable, remote display and iFlex flexible current probe makes for easier, faster, safer measurements. Clamp the Fluke 381 around a conductor, remove the display and walk across the room to operate controls or remove protective equipment, all while watching real-time readings. The iFlex flexible current probe expands the measurement range to 2500 A ac while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access. The Fluke 381 features CAT IV 600 V, CAT III 1000 V Safety ratings, an integrated low pass filter and state of the art signal processing allows for use in noisy electrical environments while providing stable readings, and proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity
Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
