p Clearing Data
Measurement data can be removed from the ND 2100G database by
the operator when this function is unlocked. Refer to "The datum
menu functions" on page 37.
Control Keys
In normal operation, the user conducts measurements using the
measurement control keys. However, when the ND 2100G is
operated from a remote computer or PLC, it is often desirable to lock
the control keys to eliminate the possibility that a user key operation
will interfere with remotely controlled measurements.
Home Lock
Normally the user can designate the home view in the Display setup
screen described earlier in this chapter. However, the home view can
be locked by the supervisor to prevent changes.
Delete 1 Record
Single database records can normally be deleted from the View screen
by the operator. Enter LOCK into the Delete 1 Record field to prevent
single record deletions.
Lock Sys
Enter LOCK into the Lock Sys field to prevent changes to Global
variables and system formulas that are used in formulas across a
number of parts.
Clr Scale Records
Channel input malfunctions cause scale error messages that can be
disabled by the user. Under some circumstances it can be undesirable
to allow the user to disable these messages and continue operation.
Enter LOCK into the Clr Scale Errors field to restrict disabling error
messages to those with a valid supervisor password.
To unlock or lock a system function:
U Highlight the desired function field
U Press the UNLOCKED or LOCKED soft key
