PROTOCOL SERIAL COMMANDS

‘Z’ Command — Perform Zero Calibration

This command is sent by the master to request the STXplus calibrate its current input A/D to

correspond with the engineering units value that was sent by the master by adjusting the zero

weight crossing point rather that adjusting the slope of delta counts/delta weight. The range of

this value can be ±2,147,483,647. The response from the STXplus will be a single digit status

where 0 - successful. For this example, the master sends the STXplus at address 01 a value of

85643. assuming that the format is set to 2(X.).
