Z-SG is a strain gauge signal converter. Measurements taken using the 6-wires or 4-wires technique are available through Modbus- RTU serial protocol or the analog output. Sensitivity from 1 to 64mV/V, settable by DIP-switch for integer values, via software for real/integer values. Stable weight indication via Modbus register/digital output. Remote writing of the tare in volatile and/or non-volatile memory by digital input/Modbus register/Modbus commands.
