tion values, sampling rate, smoothing, etc.). The menu 'sensor configuration'
can be accessed by selecting the sensor in question from the 'sensor list' and
pressing key
<KONF>
(see 10). Settable parameters are described in the oper-
ating instructions 'Digital ALMEMO ® D6 sensors' and 'Digital ALMEMO ® D7
sensors'.
15.11 Multi-point calibration
All purely digital ALMEMO
®
sensors (i.e. DIGI, D6, D7 sensors) can be cor-
rected in their characteristics by means of multi-point calibration using the
ALMEMO-Control software. DIGI sensors permit characteristics with up to 36
interpolated values; with D6 and D7 sensors each of the four primary channels
can be corrected (D6 with 36 interpolated values in total, D7 with 36 interpo-
lated values per primary channel). In so doing only the deviations are added to
the original characteristics (interpolated on a linear basis); accuracy is thus ap-
preciably improved. This correction process can be performed at our works as
part of a factory or DAkkS calibration or with the ALMEMO
® 204 if it has option
KL enabled.
'!' at the end of the channel designation indicates that the channel is subject to
multi-point calibration.
15.12 Special functions
On the 204 measuring instrument, in the two
Special functions
menus, all sensor parame-
ters can be accessed; these may be needed
only occasionally in routine operation but may
in many applications be very useful, (see Man-
ual 6.10) Some of these functions are highly
complex and should only be considered if the
user is fully aware of how they work and what
effect they may have.
The two 'special functions' menus can be accessed after sensor programming
by means of key

15.12.1 Cycle factor
To adapt data recording on the basis of the output cycle to the speed of
change at individual measuring points certain measuring points can be pro-
grammed with a cycle factor between 00 and 99 which will cause them to be
output less frequently or not at all (see Manual 6.10.6). Only faulty measuring
points, e.g. in the event of a limit value infringement, will always be output. This
cycle factor is by default completely disabled or set to 01 for all measuring
points; i.e. all activated measuring points are output in each output cycle. If
some other factor e.g. 10 is entered, the measuring point in question will only
be output every 10th cycle; if 00 is entered it will not be output at all.
