NOTE:
−
before starting to work with the meter, you must become familiar with this using instruction, properly
prepare the electrical system and the mechanical system, and correctly configure the parameters;
−
if the characteristics of the transducer are configured with the AR956 programmer, the transmission
parameters that must be set in the options of the ARSOFT-CFG, software, at the time of first
connection (default parameters) are the following:
−
COM port number: assigned by the Windows system after installation of the AR956 controller,
available in the “Device Manager” in the “Ports (COM and LPT)” group; see “Quick start
programmer AR956”
−
transmission speed: 2,400 bit/s
−
MODBUS address = 1
A detailed description of the configuration parameters of the transducer can be found in chapter 9.
