2-2. Reduce Sensitivity:
• Enter the ‘
Adv Setup
’ menu and scroll until you see ‘
Sensitivity
’ parameter.
• Press
CAL
to edit. Use the
DOWN
arrow to reduce this value.
• Pressing
CAL
will fire a test pulse and return the diagnostic data of the Signal size and E: distance.
Fire several test pulses for a good sample size.
• Reduce this value until the unit is no longer displaying the false echo while firing test pulses.
• Press
RUN
to save and
RUN
again to return the unit to operating mode.
• The unit will then begin to scan deeper down the length of the cable to find the next valid echo.
.
In Fig 1 you can see at 90% Sensitivity both false echoes and the correct level are considered valid targets by
the unit. At 50% Sensitivity the only echo the unit will see is the correct level
3. Blanking & Span adjustment
• If the previous steps are unable to solve a high level lock up there will be a significant signal interference.
Visually examine within the vessel for any objects near or touching the sensing element.
• Extend Blanking beyond the depth of the false echo and adjust High level so it is not within the blanked
distance.
• Perform a 15 second power cycle, the unit will re-scan for the closest signal which beyond the Blanking
distance.
• Attempt to perform Setup
Procedure A
,
B
or
C
if the unit does not locate the correct distance with the false
echoes blanked out.
