Sampling of measurement values

The input from the sensor is given to the K6CM device as a measurement value in every sampling
period. The sampling period depends on the measured target as follows.
Monitor type
Comprehensive cur-
rent diagnosis type
Vibration & tempera-
ture type
Insulation resis-
tance type
Also, until the next sampling is completed, the present measurement value is held as the PV.
When the power is turned OFF, the held measurement value is reset.
Measurement value 1
Sampling period
Measurement value 1 is the PV until
sampling of measurement value 2 is
completed.
Note The sampling of the measurement value is performed internally even in the case of the unmeasured state
before the trigger start.
