Interval and Difference (Combined)
When the delta range related to the last DIFF entry is exceeded, a new entry is
created (example: entry A) and the delta range is displaced upwards or downwards
by the delta value. As long as the measured value remains within the delta range,
logging is performed at the preset interval. The first DIFF entry is automatically
created when the data logger is started.
Limit Value (Combined)
When one of the two limit values (Min/Max) is exceeded, the data are logged as
defined by the “event interval“. Additionally, the last ten measured values before an
event are recorded (pre-trigger). As long as the measured value remains within the
limits, logging is performed at the preset “basic interval”.
