Function
These parameters are used to memorize and read out the data collected at the time of tripping or triggering.
Up to 4 kinds of data can be selected from 43 kinds of data, and the data collected at 100 consecutive
points can be stored in memory as trace data.
Here is the time at which trace data is acquired.

Tripping: Data collected before the occurrence

Triggering: Data collected after triggering
Note: To read data on a PC.
