Difference (DIFF)
When the delta range (process variable and/or temperature) related to the last entry
is exceeded, a new entry is created and the delta range is displaced upwards or
downwards by the delta value. The first entry is automatically created when the data
logger is started.
Data Logger
Example: First entry = 7, Delta = 1
Diff Interval combined (DIFF+INT)
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.
