System Alerts and Alarms

While operating the instrument, system alerts can occur. To accurately identify the source of the

alarm, each type of alarm has been given a unique status.

In addition to the status, the DataFID also has an audio alarm and an alarm LED. A soft key is

used for acknowledging alarms and is named “Accept”. To clear the alarm, press the “Accept”

key. Once acknowledged, the alarm indicators are cleared. The alarm status will remain until the

alarm condition clears.

The DataFID updates the instantaneous concentration once every second. Following every

update, the instantaneous concentration is compared to the selected compounds high alarm

level, and if exceeded, an alarm is triggered.

During calibration, all alarms are disabled. Once the calibration is complete, the alarms are re-

enabled.

User Interface – Basic Menu

The DataFID is designed for ease of use with a logically organized internal menu structure/user

interface. The DataFID’s Main Menu options are shown in Figures 13, 14, 15, and 16.

The DataFID has three soft keys under the graphic LCD display which always show available

functions of the soft keys in any screen.
