5.7.12 Reference point calibration
The reference point calibration allows calibrating the home position (height/depth) of the sensor
in regular intervals (1...999 h). This might be necessary if e.g. dirt causes deposition on the cable.
The reference point calibration compensates accuracy degradation because of dirt depositions
on the cable.
5.7.13 Passwords
You can activate passwords for different menu levels:
Password levels
Common usage
• Protection of the menus "Test" and "Setup" with a password, free access to the menu "Quick
setup". You can achieve this by activating a setup password only.
• Protection of the quick setup with a known password and confidential setup password to
protect the quick setup against arbitrary use and the setup and test menus against misuse.
This is done by activating a password for the menus "setup" and "quick setup".
5.7.14 Timeout function
Menu mode
If the user does not press any key in a 5 minutes time frame and the device is not in the test
mode, it automatically returns to the measuring mode (i.e. the display shows one or more
measuring results).
INFORMATION!
When zone tracking is the selected measuring function, the sensor will be moved out of the
medium for zero calibration.

INFORMATION!
If you activate a password for the menu "Quick setup" only and not for the menu "Setup", the
menus "Setup" and "Test" will not be protected by the quick setup password.
INFORMATION!
Independent of the mode (menu mode or test mode, see below), all changes done until an
automatic return are lost if this return happens!
