### Smart Setup Registers

The meter uses three smar t setup registers to configure all smar t input modules. The ISSB input module requires only smart register 1 to be set up.

Figure 3 ISSB Smar t Setup Registers Operational Flow Diagram

Internally, the RTD input is automatically assigned to channel 1

(CH1) and must be set up through Code 2. The RTD input feeds directly through the input module m ultiplexer to the meter s 17bit A/D converter, and then to the microprocessor for further processing.

The load cell input is processed in the input module s 16-bit A/D converter and digital signal processor. It is then f ed to some or all of the three remaining channels, CH2, CH3, CH4, where one of six outputs can be selected f or each channel from the output register map. Smart register 1 must be set up for the load cell to define the line frequency rejection, the sensor input in milliv olts per volt, and the output r ate.
