5 Configuration → Configuring analog inputs
supply lines and the signal inputs of different modules. This then
leads to beats in the measurement signal.
After selecting a carrier frequency, you have three methods of
supply:
1. No sync.(hronization)
This setting is practicable when you are only using one mod-
ule with carrier frequency supply. Within a module all carrier
frequency generators are automatica
lly synchronized.
2. Internal sync.(hronization)
Set this type of synchronization for one module. The module
then
becomes the master to which all other modules synchro-
nize.
3. External sync.(hronization)
Specify this type of synchron
ization for all other modules so
that they synchronize to the master.
For synchronization the Sync A and Sync
B li
nes in the socket are
used (Fig. 4-6, page 29).
We recommend that only one variant of the carrier frequency is
used, i.e. do not mix 600 Hz and 4800 Hz.
Do not forget to save these settings in the module and the Test
Contro
ller (refer to Section 5.3.1, Setting sensor parameters,
pag
e 107).
5.3.3 Zero balancing/taring the sensor
You have two ways of setting a measurement offset to zero, e.g.
due to preloads:
1. Zero balance
With this method measurement takes place over a certain
time pe
riod and the mean is computed. This mean value is
then subtracted from all the following measurements.
2. Taring
With this method the (single) measurement present at a cer-
tain point in time is subtracted from all the following mea-
surements.
You can, for example, perform the zero balance when setting up
or cont
rol it
using a variable.
