Introduction
This is the parameter used to lockout any unauthorized changes to the recorder’s configuration, calibration,
and pen alignment parameters. Calibration group functions are described in Section 5 – Input and Output
Calibration for Recorder with Display. Pen alignment group functions are described in Section 8 –
Troubleshooting and Pen Alignment for Recorder with Display.
Set this group last
Because this group contains functions that have to do with security and lockout, we recommend that you
configure this group last, after all the other configuration data has been entered.
