when elapsed the sludge level will be tracked again (this menu is displayed
only if "zonetracking" is selected in C1.1).
Range: 20
…
999 seconds; Default: 30 seconds
C1.7 tracking position Definition of the relative parking position of the sensor above the sludge
level (this menu is displayed only if "zonetracking" is selected in C1.1).
Range: 0.05...0.3 m; Default: 0.15 m
C1.8 start signal This menu shows the start signal for the measurement and can be set to
"Timer" (via build in timer) or "Trigger input" (via external switch on control
input 1 and/or 2). This menu is displayed only if "level" or "profile" is
selected in C1.1
C1.9 timer interval This menu shows the timer interval for starting the measurement and can
be set in minutes (this menu is displayed only if "timer" is selected in C1.8.
and "level" or profile in C1.1). Range: 1...999 min; Default: 10 min
C1.10 units This menu groups several functions to define the units of the measuring
results. These units are used for all values of the related unit group on the
display (measuring screen and parameters).
C1.10.1 height / depth This function allows to define the unit for level measurement.
Options: m, feet, inch, cm
C1.10.2 temperature This function allows to define the temperature unit. Options:
°
C,
°
F, K
C1.10.3 concentration This function allows to define the concentration unit. Options: g/l, mg/l
