*1: The recorded threshold is the multiplication result when the PT ratio and CT ratio are set.
*2: For harmonics, settings can be made individually for each harmonic order.
*3: Measurement settings can be selected for each type of measurement (inter-phase or line-to-line and -F
or -R).
*4: Plus and minus (
±) indicates that the threshold is specified as an absolute value.(Events are detected us-
ing absolute values regardless of whether they are positive or negative.)
*5: You can set the thresholds individually for channels that are separate and not off.
*6: Hysteresis is selected as a percentage value common to all thresholds in the range 0 to 10%. Frequency
hysteresis is fixed at 0.1 Hz.
*7: External events can be signals at any external event terminal, manual events or timer events.
*8: Harmonic voltage, current, power and harmonic voltage-current phase difference are available up to the
10th order during 400 Hz measurements.
