ENTERING DENSITOMETER DATA
Following a test, The operator is given the opportunity to enter optical density either manually,
automatically, or not at all. If either the manual or automatic choice is selected, the operator is
given a choice on the number of densitometer readings to average before recording the value and
prompting for a PLOT value.
Manual entry is accomplished by simply entering the density readings at the keyboard
followed by the optional PLOT value.
Automatic density readings are done by reading the densitometer via a serial interface. Before
capturing density readings the operator must have connected the densitometer to the COM1: port
of the computer through a serial cable and had calibrated the densitometer. Once
initialized, density readings may automatically be transferred to the computer by closing the
densitometer over the target area, releasing it to its normally open position, and then depressing
the transmit button located at the top of the reader. An audio "beep" will be heard after the
computer has received the data from the densitometer. Plot values are entered through the
keyboard after the desired number of density samples are entered.
CREATING A PLOT
To create a plot the operator may invoke the Plotting software by selecting the F7 (Invoke
PLOT Utility) option from the MAIN MENU or the Tech-Graph-Pad program can be used from
outside the MODEL 200 operating environment. TECH-GRAPH-PAD is started from DOS by
entering "TGP" followed by a carriage return. Once started, an entry screen is displayed, and
the Main Menu appears. Several templates of plot files have already been created by
ATLANTEK to simplify creating test plots. These templates contain a variety of information
related to labeling the plots and scaling the data. Therefore the operator must select the
"Recall a Graph" rather than the "Create a New Graph" choice. Menu options are selected by
pressing the arrow keys on the keyboard until this choice is highlighted. When highlighted,
the operator presses the carriage return to invoke the selection. From the "Recall a Graph" menu
the operator selects the "Recall an Attribute File" option. The operator must now select an
attribute file to load the previously defined template information. A listing of available
attribute files can be seen by pressing the F9 key. The attribute to be loaded depends on
the test file to be plotted. Refer to the list below to determine the correct attribute file to load
for the current data file.
