RMS value

Crest factor (CF) =

{measuring rangeCF setting (3 or 6)}

measured value (RMS)

The crest factor is the ratio of the waveform peak value and the RMS value.

SUPPORTS Crest Factor 6

When checking the measurable crest factor of our power measuring instruments,

please refer to the following equation.

* However, the peak value of the measured signal must be less than or equal to the continuous maximum allowed input

* The crest factor on a power meter is specified by how many

times peak input value is allowed relative to rated input value.

Even if some measured signals exist whose crest factors are

larger than the specifications of the instrument (the crest

factor standard at the rated input), you can measure signals

having crest factors larger than the specifications by setting a

measurement range that is large relative to the measured

signal. For example, even if you set CF = 3, CF5 or higher

measurements are possible as long as the measured value

(RMS) is 60% or less than the measuring range. Also, for a

setting of CF = 3, measurements of CF = 300 are possible with

the minimum effective input (1% of measuring range).

There are limitations on some specifications and functions. See the individual product catalogs for details.
