9.4.8 Averaging over several Measuring Points
In all measuring point scans the average value can also be determined over a
number of associated measuring points. However, for this average value a
function channel with the meas. range
M(n)
must be available
(s. 10.3.9). If you do not
wish to program reference channels and the
measuring points to be averaged begin with
M0, you need simply to program the function
channel
M(n)
to the 2nd channel of the last
connector (e.g. M13) (s. 10.3.10). This will
then refer automatically to the series from
reference channel 2 (M0) through to reference
channel 1 (M3 = 1st channel). Other ranges of
measuring points can be activated by pro-
gramming the reference channels accordingly
(s. 10.4.6). The function channel can be confi-
gured quickly and easily by means of the help
menu for
Averaging
.
Example:
M13=
M
from M0 to M3
If the sensors are to stay untouched, the function channel can also be pro-
grammed to the device internal channels (e.g. M15) (s. 10.3.10). The standard
reference channels are here M0 to M1.
