POR is % of reading.
Nonlinearity is defined as the maximum deviation (in percent error) from a straight line connecting the readings at 0 V and at 200 mV rms.

y
is the corrected result and
x
is the device output between 0.01 V and 0.3 V.
4
Crest factor error is specified as the additional error resulting from the specific crest factor, using a 200 mV rms signal as a reference. The crest factor is defined as
V
PEAK
/V rms.
5
DC offset does not limit ac resolution.
