The axes of the Graph, the columns of the Table, the sections of the Digits dis-play, and the Meter each have a data source field, which you access to choose what data to display. Selecting any of these data source fields opens a data source menu containing a list of all available data sources.
Identifying a Data Source
• In one of the simplest cases—a GLX with one single-measurement sensor connected, and no calculations or manually entered data—the data source menu contains two items, as illustrated to the right.In this example, there is only one data source option, so it is selected automatically.
Selecting the other option in the menu, Data Properties, opens the Data Properties dialog box for the selected measurement. See “Accessing Data Properties” on page 90.
• In this example, the GLX is connected to two single-measurement sensors: a Temperature Sensor and a Relative Pressure Sensor. There are two data sources to choose from. The selected data source has a check mark next to it.
The two data sources are from two different sensors, so each has a different icon.
• Certain sensors make more than one measurement. The data source menu pictured here is from a GLX connected to a Pressure/Temperature Sensor.
Note that the two data sources have the same icon, indicating that they both come from the same sensor.
• The menu pictured to the right is from a GLX connected to two sensors: a Temperature Sensor and pH/ORP/ISE/Temperature Sensor. The pH/ORP/
ISE/Temperature Sensor makes several measurements, one of which is Tem-perature. There are two data sources named “Temperature,” one from the pH/ORP/ISE/Temperature Sensor and one from the Temperature Sensor.
You can tell which sensor each temperature measurement is from by looking at the icons next to the measurement names.
Expanding the Data Source Menu
• The menu pictured to the right is from a GLX connected to a Motion Sensor.
The Motion Sensor makes three measurements: Position, Velocity, and Acceleration. Only one measurement, Position, is visible. The “More”
option that appears with a Motion Sensor icon indicates that other measure-ments are available from that sensor, but are not shown. Select “More” to see the other available measurements.
• In the menu pictured to the right, two sensors are present that each have hid-den measurements. There are two “More” options, one for each sensor. They can be distinguished by their different icons.
Accessing Data Properties
Selecting the Data Properties option from a data source menu opens the Data Properties dialog box for the selected measurement. In this example, the Data Properties for Relative Pressure would open.
To access the Data Properties of another measurement, first select that measure-ment from the data source menu, then open the menu again and select Data Prop-erties.
For information on the Data Properties dialog box, see page 69.

Multipress text input is used to enter numbers and letters through the keypad of the GLX. Each of the GLX’s input keys has a number and several letters or punc-tuation marks printed on it. In multipress mode, repeatedly pressing a key will cycle through these characters.
The 7 key ( ) will cycle through punctuation marks, not all of which are printed on the key. The characters in the cycle are:
7 ? ! @ ( ) , : ; & ~ % # < >
The 0 key ( ) cycles through two characters: 0 and a space.
The decimal point key ( ) cycles through two characters: a period (or decimal point) and E, which is used often in scientific notation.

For most users, text entry is faster and easier with a USB keyboard1 connected to the GLX. A keyboard also allows the input of capital letters in areas of the GLX environment where Shift and Caps Lock are not available.
Most keys on the GLX’s keypad have an obvious equivalent key on an attached USB keyboard. The less obvious keyboard equivalents are shown in the table below.

The GLX displays very large and very small numbers using scientific notation.
You can also input any number using scientific notation. On the GLX, the letter E, when it is placed between two numbers (with no spaces) is interpreted as meaning “times 10 raised to the power of….”
The letter E can always be input by pressing the decimal point key ( ) twice, even when the GLX is not in multipress text input mode.
Below are some examples of scientific notation and their normal equivalents.
5E2 = 500 1.234E5 = 123400 56.789E1 = 567.89 6.518E-3 = 0.006518
A lowercase e can be used interchangeably with uppercase E:
4.35e5 = 4.35E5 = 435000
A number expressed in scientific notation must not have a space adjacent to the E. The number to the left of the E can contain a decimal point, but one is not required. The number to the right of the E must not contain a decimal point.

The Graph, Table, Calculator, Sensors, Output, Notes, Meter, and Stopwatch screens can all be printed on certain models of printers2 connected to the GLX’s USB port. In these screens, select the print command (or commands) from the
menu.
To install a printer on the GLX, simply connect it to the GLX’s USB port using the cable that came with your printer. Drivers for compatible printers are factory installed on the GLX and updated whenever the GLX receives a firmware update (see page 93).
