MicroFID Software Manual
Beginning Operation
To print or review logged data, you can operate MicroFID without
the flame. You conserve the hydrogen this way.
If you choose to start the flame, MicroFID will attempt to ignite the
flame once you have turned on the flow of hydrogen gas. If
MicroFID has been unused for a while it is possible that the gas
supply lines are filled with air. If the flame cannot be started,
MicroFID will begin a 30 second purge cycle. During the purge
cycle it will flush the gas supply lines with hydrogen. After the
purge cycle it will attempt to light the flame again. If it fails again,
another purge cycle will be performed and MicroFID will try a third
time to ignite the flame.
To operate MicroFID:
1. Turn the instrument on by pressing the front of the On/Off
switch. When the instrument is powered up, the version
number and creation date of the instrument software are
displayed. Press ENTER.
2. You will be prompted to start the flame. If you do not want to
start the flame, use the ARROW keys to select “N o Flame
Needed” and press ENTER. To start the flame use the
ARROW keys to select Start Flame and press ENTER.
3. If you selected “ Start Flame”, MicroFID will prompt you to
start the flow of hydrogen. Turn the shut­off valve
counterclockwise to start the flow of hydrogen and press
ENTER. See Figure 1 for the location of the shut­off valve.
4. The pump will start and MicroFID will then ignite the flame.
You will hear a small pop when the flame has been ignited.
Once the flame has been started the message “D etector flame
has been started OK” will be displayed followed by the default
display, shown in Figure 4.
