3.3 Programming Mode
3.3.1 Front Panel Operation
Programming mode allows the user to configure the instrument for a particular
application, and to perform protected management functions such as the resetting of
the data keeping registers and the setting of RTC.
Password Protection
Programming mode has various levels of authorization to provide safeguards
against unauthorized changes in the instrument setup configuration:
• view level non-protected level: can view all setups and list configuration
parameters. No changes allowed. No password needed.
• protected level can view/modify setups and perform management functions
(reset, RTC update)
• superuser level- privileged level: all functions allowed at the protected level
plus user protection override. This level is intended for
service procedures, and is not normally accessed by the user.
It is protected by the factory set superuser password.
Entering the protected level is protected by the user password. The user can set
password, and disable or enable password control. With password control disabled,
the user enters the protected level without password checking.
NOTE
The instrument is shipped with password protection disabled. To restore password
protection, the user should explicitly enable password control from the
PASSWORD PROTECTION CONTROL menu (see below).
F When password protection is enabled, the instrument automatically
prompts for the password when you attempt to access the protected
level. Store your password in a safe place. If you do not provide the
correct password, you will need to contact your local distributor for
the superuser password to override password protection.
