4.4 Setting up System Security
The passcode feature of the sc100 restricts unauthorized access to configuration and
calibration settings. The passcode is factory set to sc100 (the five digits must be followed
by a space 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 ). 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, see
Section 9 on page 45 .
