10 OVERVIEW OF PARAMETERS
Parameter Description
MaxCol See “8.4.2 Filtering measured values”.
MeasMd Measuring mode
• HiSpd: max. length = 2,005 mm, response time
< 400 ms
• HiAcc: max. length = 6,005 mm,
response time < 2,800 ms
(more stable measured values, recommended for liq-
uids with low DK values and where TrsHld is < 70)
• mode-1: not supported, deactivates current AutCal/
foam calibration
Pulse See “8.4.5 Selecting evaluation process”.
AutCal See “7 Commissioning”.
TrsHld This value describes a factor which determines how strong
an echo has to be in order to be recognized by the device.
The value range lies between 20% and 500%. The default
is 100% in this case. Only shown if password entered.
• 20% = high sensitivity
• 100% = standard
• 500% = low sensitivity
AutoTn See “8.4.3 Automatic interference signal limit adjust-
ment”.
CalRng Calibration area / calibration length (calibration range)
• Value range: 95 mm ... 6,005 mm
Range starting from the process connection in which
static interference signals (coupling sections, welds, spray
balls, etc.) are hidden during the AutCal process. During
the AutCal process, there must not be any medium in the
defined area of +200 mm.
See “8.4.8 Teaching in static interference signals”
(LFP Inox).
MaskZn See “8.4.4 Blanking interference signals in masked zone”.
MaskTr See “8.4.4 Blanking interference signals in masked zone”.
Reset Resets the value for AutCal.
Foam See “7.3 Foam commissioning (with factory settings)”.
CalEmp See “7.3 Foam commissioning (with factory settings)”.
CalMed See “7.3 Foam commissioning (with factory settings)”.
Limit Limit between foam and fluid
• Range: 20 % ... 100%
• Factory setting: 90%
• Medium surface: 90%
• Foam surface: < 90%
When measuring the foam surface, it may be necessary to
reduce the limit. If the sensor displays a limit value that is
too low, it is necessary to reduce the limit.
