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.
Example: First entry = 2, Delta = 1

Diff Interval Combined (DIFF+INT)
When the delta range related to the last DIFF entry is exceeded, a new entry is creat-
ed (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.
