8. The MicroFID II will automatically start with “MicroFID II Setup” on the main display. Simply press the
middle red soft key (“meas”) to initiate the “Flame ON Procedure.” After a few moments, measurements in
ppm should be shown on the display, and the flame icon should be present.
9. The calibration function is initiated by pressing both the left and right soft keys at the same time.
NOTE: See Calibration section immediately following these steps for a full discussion on the calibration
process.
10. To turn off the MicroFID II, follow the steps shown on the Shut Down MicroFID II Menu, Figure 15 in
Chapter 3 User Functions.

Calibration
The MicroFID II must be calibrated in order to display concentration in ppm units equivalent to the
calibration gas. See the section on calibration starting on page 59 for a full description of calibration
procedures for the MicroFID II. The MicroFID II must be operated in an upright position during calibration.
Data Communication
The MicroFID II links to external devices via Bluetooth. This wireless technology is used as the
communication link to external PC’s used for uploading information to the MicroFID II and for
downloading measurement data collected during the process of field monitoring activity. It can also
communicate with external PDA
’s which may be used for Method 21 LDAR monitoring
Refer to Chapter 4 for more information regarding Bluetooth communication set-up and operation.
Response Factors for Gases and Vapors
To use the response factors:
1. Press the CAL key and enter the response factor for the specific compound.
2. Calibrate the MicroFID II with zero air and 500 ppm methane as described in the section on
calibration
3. Expose the MicroFID II to the sample. The displayed reading is the approximate concentration
of the specific compound.
The response factors on the INFICON web site serve as a guide to concentrations measured by the
MicroFID II.
NOTE: It does not matter which Cal Memory is selected or which response factor is entered, MicroFID
II
’s response is not specific to any one compound. The displayed reading represents the total
concentration of all ionizable compounds in the sample.
