9. REGULATION PARAMETERS
Description of columns in the Table of Parameters
• Par
.:Listofconfigurabledeviceparameters;
• Description: Indicates parameter operation and any possible selections;
• MU: Measurement unit relating to the parameter;
• Range: Describes the interval of values that the parameter can assume. This can be correlated with other instrument
parameters (indicated with the parameter code).
NOTE
:
if the actual value is outside the permitted limits for that parameter (for example, because other parameters
defining the aforementioned limits have been altered), the value of the violated limit is displayed instead of the actual
value;
• Default
:Indicatesthepre-setfactoryconfiguration;
• PW: Indicates the access level for the parameter.
• MODBUS address: Indicates the address of the MODBUS register containing the resource you want to access.
