Additional information This parameter defines the interval between the individual data points in the data log, and
thus the maximum loggable process time T
log
:
• If 1 logging channel is used: T
log
= 1000 ⋅ t
log
• If 2 logging channels are used: T
log
= 500 ⋅ t
log
• If 3 logging channels are used: T
log
= 333 ⋅ t
log
• If 4 logging channels are used: T
log
= 250 ⋅ t
log
Once this time elapses, the oldest data points in the data log are cyclically overwritten such
that a time of T
log
always remains in the memory (ring memory principle).
The logged data are deleted if this parameter is changed.
Example
When using 1 logging channel
• T
log
= 1000 ⋅ 1 s = 1 000 s ≈ 16.5 min
• T
log
= 1000 ⋅ 10 s = 1 000 s ≈ 2.75 h
• T
log
= 1000 ⋅ 80 s = 80 000 s ≈ 22 h
• T
log
= 1000 ⋅ 3 600 s = 3 600 000 s ≈ 41 d
