Data Logger
Operating Modes of the Data Logger ( Logger Type)
Shot
In this mode, a measured value is recorded when the Save value softkey is
pressed. In the measuring mode (meas), it is always possible to hold a value
and then save it.
Difference
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 fi rst entry is automatically
created when the data logger is started.
Interval (time-controlled)
In the “Interval” mode, the data are cyclically recorded.
Example: Logger type “Interval”
