Averaging
11.4.8 Averaging over measuring points
In all measuring point scans the average value
can also be determined over a number of as-
sociated measuring points. However, for this
average value a function channel with the
measuring range
M(n
)
must be available (see
12.3.9). If you do not wish to program refer-
ence 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) (see
12.3.10). 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 programming
the reference channels accordingly (see 12.4.6). The function channel can be
configured quickly and easily by means of the wizard menu
Averaging
.
Example:
M13=
M
from M0 to M3
If the sensors are to remain unaffected, the function channel can be pro-
grammed to the device-internal channels (e.g. M19) (see 12.3.10). The default
reference channels are M0 to M1.
