Assuming the operator has access (via RUN/PROG key or access code), the numeric keypad can be used
to key in a new value or the decrement (m) and increment (l) keys can be used to decrement or increment
the value. The graph will immediately reflect the changes made. Note that by holding down the
decrement and increment keys the operator can effectively “drag” the setpoint graphically to where it
needs to be. The key thing to remember is that the increment and decrement keys apply to the value the
editing cursor is currently on.
An additional editing method is provided for setting the data window start and end angles. When a data
window is selected and the editing cursor is on the start angle parameter in the information box, a
softkey with the legend “SET DW START ANG AT CURSOR” will appear. Pressing this key will set
the data window start angle where the measuring cursor ( “h” in Figure 4.5), not the editing cursor, is
positioned at. If the angle read out (“a” in Figure 4.5) indicates 167.0 degrees and the SET DW START
ANG AT CURSOR softkey is pressed, the system will attempt to set the start angle for the currently
selected data window (as shown by the highlighted data window name - see “o” in Figure 4.6) to 167.0
degrees. Note that this will fail if for some reason the angle would be invalid - such as a start angle
larger than an end angle. The same procedure can be used for the data window end angle, with the
softkey reading instead: “SET DW END ANG AT CURSOR”. Note that data windows can overlap, but
the settings for the first (lower numbered) data window will take precedence. For example, if data
window 2 and data window 4 overlap, the settings for data window 2 will be used in the overlapped
portion of the stroke.
Section 4.5.3 Sending the Graph
The SEND GRAPH softkey commands the tonnage monitor module to transmit all present tonnage data
through the operator terminal to an internally stored reference graph for the current job, external laptop
computer, or to the LinkNet networking host computer. When this softkey is pressed, a list will “pop-
up” with the available sending options. Note that not all options may be available at any given time.
The sections detailing each option will indicate when that particular option is available.
Section 4.5.3.1 Store As Reference
When equipped with a flash storage card, the OmniLink can store one “reference” tonnage waveform per
job. This reference waveform can be overlaid with the current waveform to make a direct on-screen
comparison of the two. The “Store As Reference” selection of the SEND GRAPH softkey will retrieve
the tonnage waveform from the tonnage monitor, make a reference waveform from it, and store it under
the current job number. The progress of these operations is shown at the top of the screen just above the
tonnage graph in a special progress window. Note that this operation is a restricted operation and may
require the RUN/PROG key and/or an access code depending on system configuration (see Section 2 for
details). Depending on the number of channels, the number of samples taken, and the way in which that
particular tonnage signature compresses the transmission time can vary from a few seconds to thirty or
forty seconds. After success or failure is reported, press any key to resume normal operation of the
screen.
Section 4.5.3.2 Send To Laptop
This option is only available if the laptop interface has been set up in auxiliary communications. In
addition, a computer with the Link Graphical Tonnage Analyzer must be connected to the laptop port for
