Locked Calibrations
The 45MG includes a password-protected locking function to prevent changes to
setups, and prevent access to certain functions. A change to the calibration is one
action that can be locked. In such case, the message shown in Figure 5-10 on page 61
appears momentarily on the help text bar (see “Locking the Instrument” on page 136
for details).
