6. The instrument status will again be “Locate”. If you
recorded the sites in order, the next site will be displayed.
You can move through the stored list. If the sites were not
entered in order or the order of sites has changed, use the
“F ind” option to locate the next site.
7. Press EXIT at any time to return to the beginning of the
current event and repeat the readings.
8. To repeat a measurement recorded previously in the
datalogger, press the EVENT key and use the ARROW
keys to select “ Find”. Select the event you need to repeat
and press ENTER.
If you change from Method 21 operation to a set averaging interval,
you will lose your Method 21 schedule and associated
programming. Print or save the data to disk before changing the
interval. See PRINT Key on page 53, GRAPH Key Mode on page
58 or Computer on page 88 for details of printing or saving your
data.
NOTE:
The datalogger will be cleared when you change from Method 21 to
Interval mode.
Response Factors for Gases and
Vapors
In situations where only a single pure compound is present in air,
MicroFID should be calibrated with a standard of that specific
compound as span gas. MicroFID’s 10 Cal Memories can be used to
store calibration information for 10 different span gases.
MicroFID’s reading will always be influenced by any other
ionizable compounds present in the air sample. Even if MicroFID
has been calibrated with a specific compound, its response is not
specific and the presence of another ionizable impurity may render
the numerical result invalid.
It is often impractical to carry a range of different standards into the
field. Approximate results can be obtained by calibrating MicroFID
