DETAILED SETTINGS
Comparing Measured Values (Previous Value
Comparisons)
Use the previous value comparison function to ignore gradual changes in measured values
over time, due to factors such as temperature drift, and only detect and judge sudden
changes.
The hold function must be set before previous value comparison can be set. The difference
from the previous hold value with a PASS judgement becomes the measured value.
For example, if the judgement for that previous measurement is HIGH or LOW, the
comparison is performed with the hold value before that.
