Additional information
A total of 500 measured values can be logged. This means:
• 500 data points if 1 logging channel is used
• 250 data points if 2 logging channels are used
• 166 data points if 3 logging channels are used
• 125 data points if 4 logging channels are used
If the maximum number of data points is reached, the oldest data points in the data
log are cyclically overwritten in such a way that the last 500, 250, 166 or 125
measured values are always in the log (ring memory principle).
Note:
The logged data are deleted if a new option is selected in this parameter.
