• For current (RMS value, inrush current, and peak current), when the reference value (measured value) is 10% or less of the range, 10%
of the range is used as the threshold value, and when the reference value (measured value) exceeds 100% of the range, 100% of the
range is used as the threshold value.
• When the RMS voltage is less than 3% f.s. of the range, 5% of the
range is used as the upper limit, and 0% of the range is used as the
lower limit. When the voltage peak value is less than or equal to 3% f.s. of the range, 5% of the range is used as the threshold value.
• For total harmonic voltage and current distortion as well as harmon
ic voltage, functionality is disabled when the measured value (volt-
age RMS value or current RMS value) is less than or equal to 3% f.s. of the range.
• If VT or CT is changed after simple configuration (including when
changed outside of the simple configuration process), the threshold
and sense values will not change. (Either repeat simple configuration or reconfigure the event threshold values after setting VT and CT.)
• As a rule, settings not included in the table are set to OF
F (other than manual events).
