Table III.1
Define a test by first selecting a test mode. Rotate the Select / Scroll knob until the required test
mode is displayed, then press the Select / Scroll knob to confirm your choice. As the test modes
are displayed, the parameters specific to that mode will be shown with the previously selected
parameters.
Once a test mode is selected, the cursor will move to the first parameter. You may either select that
parameter to enter new values by pressing the Select / Scroll knob or you may scroll to the next
parameter by rotating the Select / Scroll knob.
Data entry is accomplished by setting each digit individually. For example: to set a value of 57.0 as
the target distance, rotate the Select / Scroll Knob until the “D” in “Distance” is blinking. Depress
the Select / Scroll knob to get to the tens digit, then rotate the knob to the value 5. Depress the
Select / Scroll knob again to get to the ones digit, then rotate the knob to the value 7. Depress the
Select / Scroll knob to get to the tenths digit, and depress it again to leave the value at 0.
A data entry of zero in all columns for any parameter will result in that parameter being reset to
the previous value. Pressing the Select / Scroll knob without first rotating it during the data entry
process will result in a zero being placed in that column. This can expedite the entry of Trigger
values since in most cases the first one or two columns will be zero (004.0 grams).
Display Conventions
The CT3 display contains four lines, but some result screens contain additional lines of information.
In order to show more than four lines of information, screens are allowed to scroll using the Scroll
knob. Scrollable screens are identified by the 
symbols in the upper right corner of the display.
Whenever these symbols appear, the display can be scrolled up or down as indicated to show the
lines above or below those presently displayed. In the following section describing test modes, all
possible displays are shown. For those having more than four lines, the additional lines are shown
in
grey tex t
as seen in figure III.3.
