2.4 Overview of Parameter Configuration
Table 4 shows the standard (“Default”) and possible parameter configurations of the clamp-on flowmeters.
This user manual is dealing with the standard configuration. For setting up other configurations the Levitronix
®
Service Software is needed. Consult the Levtronix
