is necessary to check that the signals reflected from the media interface
and reference reflector (for AS with reference reflector) are displayed. If
the Device is configured correctly, the measured distance is equal to
the actual distance, and positions of the selection marker and the
desired echo-signal match on the display.
Note: The value of measured distance is displayed in the
Signal
view
window, presence of the desired echo-signal is detected by the
icon
indicated in the lower left corner.
If the selection marker matches the image of a noise echo-signal,
the Level gauge should be reconfigured as described below.
In the menu

by:
the operator selects one of the criteria by which the desired echo-
signal is detected among the following:
-
max (A)
- a signal with maximal amplitude within the specified
measuring range
-
min (D)
- a signal corresponding to the closest distance within the
specified measuring range
-
max (D)
- a signal corresponding to the longest distance within the
specified measuring range
-
max (D
∗
A)
- maximal value of the product of signal amplitude into the
square root of distance within the specified measuring range.
The manual alignment mode is selected from
Signal view
window.
When you press the button
in
Signal view
window, the selection
marker starts blinking, and you can move it using buttons
,
. While
in the moving mode, the selection marker is positioned at the desired
signal. After pressing button
, the tracing mode is activated, and the
marker stops blinking.
5.2.7. If necessary, you may configure the interval log and clear logged data.
Data is cleared from the
Data logs
menu, the same for event logs is
done from the
Status logs
menu.
5.2.8. The Level gauge is powered off and switched to OPERATION mode by
removing a jumper from the terminal used for modification of service
parameters. This service terminal is sealed. If necessary, two fixing
screws are sealed from the front panel side of BMD.
5.3. Special-purpose configuration
5.3.1. Special-purpose configuration is performed if required. Typically, this
configuration procedure is carried out on the sites where gas
composition differs considerably from the air composition or is
unknown.
5.3.2. Special-purpose configuration is performed for the Level gauges having
acoustic systems complete with RTDs (sensitive element): AS-11x-xx3,
AS-61x-xx0, AS-62x-xx0, AS-71x-xx0, or AS-72x-xx0. The procedure
follows the general configuration procedure and is made for the Device
being switched in SERVICE mode.
