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 setting.
Enabled: Certain calibration and Test/Maint settings/operations cannot be accessed without
the passcode. If the passcode is enabled, it may be edited (see
section 4.4.2 ). The passcode can
consist of 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 changed passcode is forgotten, obtain the Master passcode from the Technical Consulting
Services Department.
