Power Quality Analyzer Model 8335
3.2.4 Current Probe Accuracy
(to be added to the PowerPad’s accuracy)
Sensor errors are offset by a typical correction inside the device. This typical
correction, applied to the phase and amplitude, depends on the type of sensor
connected (detected automatically) and the gain in the current acquisition channel
used.
The RMS current measurement error and phase error are additional errors
(which must therefore be added to the device errors), indicated as influences on
the calculations carried out by the analyser (powers, energies, power factors,
tangents, etc.).
