Functions
7.6 Service (menu 6)
The write protection is automatically enabled the next time the system is switched to the initial
operating view.
Note
Attention
Programming is permanently enabled as long as the code is 0.
Service code (menu 6.3)
The calibration data and factory settings of the device are protected by a service code. The
relevant menus are available only after entering this service code. For normal operation it is not
required to enter the service code.
Reset (menu 6.4)
A reset of the unit can be made without change of parameters (warm restart). Totalizers are not
reset.
Control values (menu 6.5)
In this menu, device-internal data used mainly for diagnosis for the used paths can be read.
The values displayed in the individual menu depend on the respective application (medium).
The following data are available:
• Gain
• Amplitudes
• Trigger level
• Error count %
• Time of flight - up (TOF up)
• Time of flight - down (TOF down)
• Difference in time of flight (delta TOF)
Gain (menu 6.5.1)
Every transducer gain level can be read.
These parameters are read only values and within the range of 0 to 255.
Unused paths will show 0. Normal values are in the range of 40 to 100. High gain values refer
to a high sound absorption in the medium (maximum 255 for no sonic transfer, for example by
empty pipe or if no sensor cable is connected).
