user to compare the Leak Definition with the Corrected value. Once the comparison is
performed, the status key should be selected by pressing the ‘status’ soft key. The screen will

Figure 27. Method 21 Mode Status Display
The user can choose the status for the current tag by first moving the cursor up or down to the
proper status designation and then press the ‘select’ soft key. Once a status designation is
chosen for the current tag, the MicroFID II automatically increments to the next tag and the
whole process is repeated starting with Figure 22.
If a repeat reading for the same tag is needed, press the ‘view’ soft key and select the specific
tag by moving the cursor to the appropriate location. Then, press the ‘select’ soft key. The
display as shown in Figure 22 will be presented.
Logging Off
In the Logging Off mode, the MicroFID II will display the current TVOC reading but will not log
any values or display any Location strings. Logging Off will continuously display the
concentration of total volatile compounds present that the MicroFID II can ionize. The reading is
updated approximately once per second. Logging Off mode has the same display format as the
Interval Mode.
Data Logging
The MicroFID II reading is updated once a second. In the background, the MicroFID II is
sampling the concentration and logging the average concentration for either a selected time
period (Interval) or at the time the trigger key on the probe is pressed (Location and Method 21).
All logs record the date, time, status, and TVOC reading. In the Location and Method 21 modes,
a character string up to twenty characters is also recorded. In addition, Method 21 mode adds
more details to a log which are
described in the ‘Method 21 Operation’ section.
