Interruption (Instantaneous power interruption)
Set the interruption threshold (rms voltage in one cycle) as a percentage
of the nominal voltage. The selectable range varies depending on the
VT ratio. Hysteresis is applied to this threshold. To detect events at rms
voltages of 10 V or less, be sure to enable the interruption event. Proper
detection may not be possible by setting a similar threshold for dip.
Settings
0 to 100 % (10 %*) of the nominal voltage
* Default value
<Procedure>
Use the up and down arrow keys to move to INT.
