[Example 5] Monitoring the power of a voltage dip
The following are the procedures to monitor the power of a voltage dip.
Procedures
1.
As the input voltage region of the 2321-20 is ±50 V, connect
the tip of the input terminal to a step-down transformer to
reduce the voltage to ±50 V.
2.
Set scaling.
3.
Set the window in of the analog, trigger filter.
Set the voltage level to a level that the trigger cannot fall
below, and the power frequency of the trigger filter to above
half-wave (above 10 ms for 50 Hz and above 8.4 ms for 60
Hz). The trigger will be activated when the voltage is above
half-wave and below the pre-set level.
