Measurement of operation intervals
4.1.5
The DPOS01 function can measure operation intervals (OT1 to OT4) †; the intervals OT1 to
OT2 can represent the period of time when a switch changes from "Closed" to "open". In the
DPOS01 function, the operation period is grouped into sub-time periods, as shown in Table
4.1-25. The user should set scheme switch [DPOS01-OPETMEN] to On.
