APPENDIX B: KISTLER-MORSE ® 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.).
