Sequence Site Master Calibration – Control Byte #13 (0Dh)

Description: Initiates a calibration step. The Site Master must be calibrated to give accurate measurements.

The command sequence must be sent in correct order. i.e. Open -> Short -> Load. You can also abort the calibration by

command – “Abort” before the command - “Load” is sent. Once command - “Load” is sent, calibration is completed, and the

old calibration data is lost.

The unit under test returns #255(FFh) upon receiving the command, and return #240 (F0h) when the calibration of the

connected component is completed, then waits for further commands to complete the whole calibration process.

This command is designed to be executed step by step: open, short, load. Issuing any other command during this command

sequence will cause undesired results.
