Notice the three options in the frame of controls located at the upper left of this window. Although the Other function you chose from
the Run window is currently selected, two other configurations (functions) can also be chosen at any time. These were already
described in section 4.2.5.1 and section 4.2.5.2. The main benefit of this frame is that the user can freely change between the three
configurations of the AutoLog window, without having to return to the Run window, no matter which button opened this window.

This configuration of the AutoLog window shows all other (non-test# specific) status items and associated editable options that can be
changed in the Level Scout. The white status frame shows three items including: Battery status (and options), Memory status (and
options), and Date/Time status (and options). Double-clicking this frame’s title will refresh all the Other status items by re-reading
them from the transducer and redisplaying them. Double-clicking just the label above a particular status box will refresh that one item
only. Three frames surrounding the white status frame allow changeable options of these various items (labeled in light green value
fields) to be edited as needed. White value boxes show status values only and cannot be edited directly. For more information view
the ToolTips of all these various fields for instructions on how to interpret them and edit them.

The only Date/Time option is a check box that allows the user to request that the date/time in the transducer be synchronized with the
PC’s date/time. The user may also be prompted to use this option when tests are uploaded from a transducer if PC and transducer are
not currently synchronized in time. Double-clicking this frame’s title will refresh Date/Time status and options only.

The Data Memory Options tells the transducer what to do when it runs out of memory during a test. The test (and any future pending
tests) can either stop (No Wrap), or the transducer’s firmware can start reusing memory occupied by earlier samples starting with the
first sample recorded (Wrap). There is also an option to erase all memory. This check-box option should only be checked when the
data from all the tests have been extracted. Double-clicking this frame’s title will refresh Memory status and options only.

The Battery options frame shows the current type of battery, its “new” capacity (both fields are initially dim), and the last Date
Installed. The light green fields can be edited only after the transducer’s batteries have been changed which is acknowledge by
checking the New Battery check-box. Setting the type and capacity correctly is essential if the status field (showing the amount of
battery power remaining) is to be maintained correctly. Click the New Battery check box only on the day you change the battery. The
Date/Time Synchronize function is also checked for you, since it is a prerequisite to executing the New Battery command. It is
executed before the New Battery command when both are checked. The Date Installed field will be updated (with today’s date) after
the New Battery command has been successfully executed. Double-clicking this frame’s title will refresh Battery status and options
only.

The bottom half of the window contains two frames of “global” test parameters: Alarm Scanning and Broadcast. These are parameters
that can be associated with the currently active test, but without having to be specified as part of a particular test.

The Alarm Scanning Method options, allow each active test to have a common alarm checking function enabled or disabled in
addition to that test’s normal scanning method. Up to four unique alarm limits can be specified: Alarm High, Warn High, Warn Low,
and Alarm Low. To disable a particular high limit, specify a pressure value that is much higher than the transducer can generate (e.g.,
9999 pressure units). To disable a particular low limit, specify a pressure value that is much lower than the transducer can generate
(e.g., -100 pressure units). The checkbox must be checked to enable the alarm checking function for the current test. However, since
this alarm feature is global to all tests, every other test that becomes active will also use the alarm check feature if the checkbox remains
checked.
If the period parameter is specified (a positive non-zero value in days_hours:min:sec) then this special “alarm check” period
will control the alarm checking scan rate during the time the scanned pressure value falls within an “alarm/warn” band of values. If the
period is disabled (set to zero: 0_0:0:0) the original period of the test’s normal scanning method (Linear, Logarithmic, etc.) will
continue to be used after the pressure value goes “in alarm” (i.e., falls within an “alarm/warn” band of values). Double-clicking this
frame’s title will refresh the Alarm and Broadcast status and options.

The Broadcast options, in the bottom right frame, can enable or disable two independent broadcast functions. Broadcasts cause user-
readable messages to be output by the transducer on the SDI-12 serial bus when either or both of the following logs occur for the
currently active test:

(1) When any scan is logged, and/or

(2) When a scan is logged that is “in alarm” (i.e., the pressure value is not within the Normal value band, but is within

any defined warn/alarm band of values) and Alarm is enabled.

Double-clicking this frame’s title will refresh all “global” status and options (Alarm and Broadcast).
