3. Next, select the operating range. This option sets the full­scale
range for the bar graph display, the graph output. Use the
ARROW keys to select a Range of 20, 200, 2000, 10000,
50000 ppm. This does not affect MicroFID’s numeric display
and datalogging.
4. Select the Interval next. You can average data over intervals of
1 second (s) 5 s, 10 s, 15 s, 30 s, 1 minute (m), 2 m, or 5 m.
You may also select Method 21 mode.
If you select Method 21, the datalogger will be cleared. If you
do not want to lose your previously recorded data, press EXIT.
Then print or save the data to disk before changing the interval
to Method 21. See PRINT Key on page 53, GRAPH Key
Mode on page 58 and Computer on page 88 for more
information on printing and saving logged data.
NOTE: The datalogger will be cleared when you change from Interval
mode to Method 21.
Method 21 mode first prompts you to locate a specific
sampling site and then allows you to record both a background
and sample entry in the datalogger. Method 21 mode will be
covered in more detail on page 72.
5. The date option is next. Enter the current day, month and year.
Press ENTER to confirm the entry. The date is retained when
the instrument is turned off. You do not need to enter this
information every time you use MicroFID.
6. Next enter the correct time. Press ENTER.
EVENT Key
Events may be used to identify a particular sample or sampling
location in memory. An event name is used in Method 21 operation
to identify a sampling location. Recorded data are played, printed
and removed from the datalogger by specifying a start and stop
event name.
