The meter has three smart setup register s to configure all smar t input modules. The reference voltage and output rate for both input signals are configured in smart register 1.
Potentiometer signals, POT 1 and PO T 2, are then individually softw are selected for a combination of tw o meter channels. Either signal can be selected for Channel 1 via Code 2, Channel 2 via Code 4, Channel 3 via Code 5, and Channel 4 via Code 6.
