be needed. (E.g. Avtron) Size of the load bank depends on
model and phase mode. A load is required to perform the
current measurement calibration near full scale. Current
measurement calibration should be done on the lowest
available voltage range.
The accuracy and value of the load resistor is not critical as
long as the current drawn is sufficient to operate the AC Source
in the upper current range (80-100 %). Suggested values of
load bank settings for current measurement calibration
purposes are shown in Table 6-1.
