Vers. No. 6.1110 Released: 25/04/20175 Configuration → Configuring analog inputssupply lines and the signal inputs of different modules. This thenleads to beats in the measurement signal.After selecting a carrier frequency, you have three methods ofsupply:1. No sync.(hronization)This setting is practicable when you are only using one mod-ule with carrier frequency supply. Within a module all carrierfrequency generators are automatically synchronized.2. Internal sync.(hronization)Set this type of synchronization for one module. The modulethen becomes the master to which all other modules synchro-nize.3. External sync.(hronization)Specify this type of synchronization for all other modules sothat they synchronize to the master.For synchronization the Sync A and Sync B lines in the socket areused (Fig. 4-6, page 29).TipWe recommend that only one variant of the carrier frequency isused, i.e. do not mix 600 Hz and 4800 Hz.Do not forget to save these settings in the module and the TestController (refer to Section 5.3.1, Setting sensor parameters,page 107).5.3.3 Zero balancing/taring the sensorYou have two ways of setting a measurement offset to zero, e.g.due to preloads:1. Zero balanceWith this method measurement takes place over a certaintime period and the mean is computed. This mean value isthen subtracted from all the following measurements.2. TaringWith 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 upor control it using a variable.
