Changing the System of Units
The GF-A2100/GF-A2200 transmitter is shipped with the system of units set to US inch-pound units (IP), and will display
units of measure as shown in the IP column of Table 2. To change to standard international (SI) units, simultaneously
press and release the “UP” and “DOWN” arrow pushbuttons during normal operation to enter the SETUP menu. Then,
using the ENTER button, navigate into the SYSTEM SETUP menu to the System of Units sub-menu as shown in Figure 13.
Press "ENTER" to proceed to the right (three times), and then use the "UP" and "DOWN" arrow buttons to select the sys-
tem of units desired. Press the “ENTER” button to save the changes, and then press “ESC” twice to move left and return
to normal operating mode. Note that all Menu illustrations are shown in IP System Of Units. When SI System of Units is
selected, the menu units of measure abbreviations change as shown in the SI column of Table 2.
Factory Default Settings
The GF-A2100/GF-A2200 transmitter is “plug and play” and does not require additional setup unless an optional feature
is selected that requires configuration. Table 3 shows the factory default settings for the GF-A2100/GF-A2200. To
change the Factory Default Settings, see CHANGING FACTORY DEFAULT SETTINGS section in this document.
GF-A2100/GF-A2200 LCD Display Notifications and Features
Following a brief initialization at power up, the LCD will automatically display airflow and temperature as all upper case
(caps) characters. The LCD display provides additional information on system status and alarm conditions as follows:
LCD Scrolling Control Feature (SYS CFG=DUAL)
When the GF-A2200 is configured for two probes (SYS CFG= DUAL), the LCD display will scroll to indicate the readings
for each probe. To stop the scrolling, simply depress either the “ENTER” or “ESC” keys. In this mode with scrolling
stopped, the LCD will display an asterisk (*
*) as the right most character, and depressing the “UP” or “DOWN” key will per-
mit you to cycle and hold the display at each individual reading.
