Data Logging - Files
FirstCheck+ versions 2000, 3000 and 5000 automatically logs the instruments gas readings every second
while the instrument displays real-time readings. Each reading is stored with a date and time stamp. An 8
Megabyte memory is set aside for data logging. However, when the memory is full the instrument will
overwrite previously stored data. FirstCheck+ does contain a memory full alarm that prompts the user to
download stored data (see „Instrument Menu‟).
Data Logging - Zones
To help keep track of Data logged files, FirstCheck+ allows an 8 digit identifier called Zones that can be
attached to each data file. A list of up to 199 Zones can be created on the 1stPC software and then
downloaded to the FirstCheck+ instrument. Once a Zone is selected on the instrument, all data files will
include that Zone name in the files header detail. To avoid long download times Ion Science recommends
downloading data on a daily basis. The FirstCheck+ has a default Zone called Zone 0. Unless specified, all
readings will automatically be stored in this Zone.
Zone Selection
Enter the FirstCheck+'s function menu and enter the ZONE SELECT icon. Use the UP & DOWN keys to
change the pre-programmed Zone name, then press the ENTER key to select it. A tick will appear to
confirm the selection. Press the ESC key to return to the Main Menu. Any logged data will now contain the
selected Zone name.

Alarm
When in Survey mode, all upper and lower sensor alarm levels can be set by the user to
indicate particular levels of detection specific to the users need‟s. Both alarms give an audible
and visible output (flashing LED) but with increased urgency with the upper alarm. An alarm
state will occur when the preset alarm levels are exceeded; the alarms can be reset by
pressing the ENTER key but will continue to trigger if the alarm level is still exceeded.
Please note: It is the user's responsibility to respond appropriately to an alarm condition
press the ENTER key again. Use the UP and DOWN keys to change the alarm setting. These alarms can also
be easily adjusted on a PC via the Gas Table in the 1stPC software, that is then downloaded to the
instrument via the IRDA link. Please note that for safety reasons the lower alarm cannot be set above the
upper alarm.
