3.1.4 Settings Protection
When the device is completely configured, the settings can be stored in nonvolatile
memory. When the same settings are needed again at a later time, they can simple be
loaded from this memory. In total 4 of these memory locations are available.
In order to prevent that the settings are accidentally overwritten, it is possible to setup a
password protection in the instrument. This will disable the storage of the settings in the
nonvolatile memory. All the settings are free to be changed, just the storage is prohibit.
When the instrument is delivered, the password is set to 00000. With this password the
protection is off.
There are 3 modes in which the instrument can be regarding to the password protection,
these are:
1. Protection is active
In the “memory menu” an extra line is displayed, to enter the password. On top of
this menu at the selection of the actions the “Store setup” command is not available
The “Password menu” is also not available
2. The user is logged on
To do this, the right password must be entered on the bottom line of the “Memory
menu”. After this, the selection of the “Store setup” is available again. Also the
“password menu” can be selected, by pushing 3 times on “Menu +”.
3. The protection is switched off
In this case the password is set at “0”. This is also the default condition of the
instrument. The “Password menu” is available and the extra line at the “Memory
menu” is not displayed, because there is no need to log in.
How to enter a new password is explained at the description of the password menu.
