Averaging
9.4.7 Averaging over the Cycle
The averaging mode ´
CYCL
´ must be used if average values have to be acqui-
red in cyclic periods over these periods. This ensures, that the average value is
cleared after each cycle, but appears in the display during the next cycle.
Setting the averaging over cycles:
Averaging mode: CYCL
Programming the cycle (s. 10.1.2):
Cycle: 00:15:00

Reading the average value/cycle in function:
Average value: 13.24°C
Output of all function values of the menu by using:

Average value over manual periods:
It is also possible to determine the average value over periods from one manu-
al measuring point scan to the next with the same averaging mode, but without
cycle:

Average value: 13.24°C
For recording the average values an additional
function channel
with the range
M(t)
(s. 10.3.9, 10.3.10) or the corresponding
out-
put function
M(t)
(s. 10.4.5, man. 6.10.4) is required instead of
the measured value.
