Accuracy Specifications Of The Current Probes - AEMC 8220 User Manual

3.2.6

Accuracy Specifications of the Current Probes

These characteristics are stated after linearization. The errors of the sensors are
compensated by a typical correction inside the instrument. This typical correction
is in phase and in amplitude according to the type of sensor connected (detected
automatically) and the gain of the current acquisition chain used.
The measurement error in RMS current and the phase error are additional
errors (they must therefore be added to those of the instrument alone) stated as
influences on the calculations performed by the analyzer (powers, power factors,
displacement factors, etc.).
