Description

測定時間がサイクル時間にのみリンクされた場合に可能であろう精度よりもはるかに高い時間精度によって、測定時間が予め規定されることが好ましい。一例として、測定時間の決定の時間精度は１０μｓ未満であり、および／またはサイクル時間よりも少なくとも一桁正確にされる。 The measurement time is preferably pre-defined with a time accuracy much higher than would be possible if the measurement time was linked only to the cycle time. As an example, the time accuracy of the measurement time determination is less than 10 μs and / or is made at least an order of magnitude more accurate than the cycle time .
