Menu Structure
The measurements taken by the SureTest model ST-2D are organized into a
simple menu. The first measurement in each menu selection is listed on the
face of the unit. To the right of each menu is the unit of measure for the
tests performed within that menu. The grid, and up and down arrows are
representative of how the display will indicate the units position within the
menu. The grid has four regions (one for each menu selection). When the
unit is in the line voltage menu, the first section of the grid will be shaded in
on the display to indicate that the unit is in the first menu selection. When
the unit is in the Voltage Drop menu, the second section of the grid of the
grid will be shaded in on the display to indicate that the unit is in the sec-
ond menu selection. This follows for the Ground-Neutral Voltage and Line
Impedance menus as well.
Additional tests are located in the sub-menu for each of these menu selec-
tions. An up arrow indicates that the unit is in the main menu, and a down
arrow indicates that the unit is in a sub-menu. This will be displayed just
under the menu grid on the unit’s display. Using the menu grid and menu
level indication will help the user step through the menu as indicated by the
menu structure listed on the face of the unit.
Menu Buttons
The SureTest model ST-2D uses two buttons to navigate through the mea-
surement menu. The down arrow button
(↓
) moves the unit forward to the
next menu selection. If the SureTest is on the last menu selection (Line
Impedance), pressing the down arrow button returns the unit to the first
menu selection (Line Voltage).
The side arrow button (
→
) moves the unit through all the measurements
within the menu selection. If the SureTest is in the last measurement of the
menu selection, pressing the side arrow button returns the unit to the first
measurement.
The quick reference guide at the end of this manual lists all of the available
measurements in the SureTest menu.
Display
The graphical LCD on the SureTest ST-2D indicates the value of the measure-
ment function, the test being performed and the position within the menu
structure.

Measurement Icon
The measurement icon is located on the right-hand side of
the display. The icon consists of the measurement symbol
and text to describe which test is being measured. For exam-
ple, the following icon indicates that the numerical value dis-
played is the True RMS line voltage.
