Operation
4.4 Setting up System Security
The passcode feature of the sc60 restricts unauthorized access to
configuration and calibration settings. The passcode is factory set
to sc60 (the four digits must be followed by spaces to remove the
trailing asterisk). The following two options are available:
Disabled: All configuration settings and calibrations can be
changed. This is the default.
Enabled: Certain calibration and Test/Maint settings/operations
cannot be accessed without the passcode. If the passcode is
enabled, it may be edited (
section 4.4.2 on page 32 ). The passcode
can include up to six digits (alpha and/or numeric and available
characters). If the instrument is reset using the Configure/Default
Setup menu selection, the passcode will return to the factory
default. If a passcode is forgotten, obtain the Master passcode from
the Technical Consulting Services Department.
