Variation In The Field Of Use; General; Temperature; Humidity - AEMC PEL 52 User Manual

Crest factor:
(2.8 to 360) A on the 300 A range.
■
(1.7 to 3600) A on the 3000 A range.

AmpFlex and MiniFlex
®
Like all Rogowski sensors, the output voltage of AmpFlex
proportionate to the frequency. High current at high frequency can saturate the
current input of devices.
This requirement does not consider the bandwidth limitation of the device, which
can lead to other errors.
