LCD Display Last character is an asterisk * (Scrolling Feature Engaged)
(See LCD Scrolling Feature)
LCD Display Last character is shown in lower case (Probe Malfunction)
The last character of the flow rate units on the LCD display is shown in lower case (for example C
CFm) to indicate that an
improper or malfunctioning probe is connected to the transmitter. (See Table 4 for additional troubleshooting details).
LCD Displays All Characters of Flow Rate Units in Lower Case (Field Cal Wizard Engaged)
When all characters of the flow rate units are displayed in lower case (for example cfm) the transmitter is operating in
the Field Calibration Wizard mode (see the FIELD ADJUSTMENTS - Field Calibration Wizard section of this manual). In
addition, while in the Field Calibration Wizard mode, an upper case last character indicates a probe malfunction. (Refer
to Table 4 for additional troubleshooting details.)
LCD Blinks ** LOW ALARM **, ** HIGH ALARM ** or ** TRBL ALARM **
The LCD will alternately flash to indicate that an alarm condition has been detected based on the type of alarm that has
been set in the Set Up menu (Figure 15). Alarm notifications will cease when the alarm condition is cleared. For com-
plete alarm information, refer to the G
GF-A2100/GF-A2200 Alarm Options and Description section of this manual.
CHANGING FACTORY DEFAULT SETTINGS
Setup Menu Options
The GF-A2100/GF-A2200 transmitter is configured at the factory to be fully operational when a sensor probe is connect-
ed and power is applied. Factory settings can easily be changed in the field through the Setup Menu, selected by simul-
taneously pressing and releasing the “UP” and “DOWN” buttons while the transmitter is in its normal operating mode
(see Figure 15 for detailed flow chart of the Setup menu). Changes made in the Setup menu take effect immediately.
The following are common field changes to the factory default settings.
Output Scaling
Sensors are individually calibrated in wind tunnels (traceable to the National Institute of Standards and Technology
[NIST]) between 0 and factory default full scale. Sensors are independent and produce “percent of reading” accuracy.
Decreasing the full scale does not alter (or improve) the accuracy of the device. Factory default output scaling for the
GF-A2100/GF-A2200 can be changed by entering the setup menu through item *FS= setting (as shown in Figure 15).
Locking the Configuration Settings
Using the
Lock Menu
, transmitter configuration settings can be secured by entering a user defined lock code from 1 to
9999. Once locked, user defined settings can only be altered after entering the defined lock code in the
Initialization,
IP/SI Units
or
Setup
Menus. To enter the
Lock Menu
, press the “ESCAPE” and “UP” arrow simultaneously at any time.
To enable the
Lock Menu
a code must be entered, and then verified. Figure 14 details the Lock menu.
VIEWING SENSOR DATA
Data from the sensors can be displayed locally on the LCD from the Diagnostic sub-menu as detailed in Figure 15.
