Galaxy® Gas Analyzer — Operating manual
Flow Fail
The instrument’s internal pump can be stalled when pulling against a vacuum or through a
blocked filter. This is indicated by a flashing pump
icon ; to prevent damage to the pump, the
pump will switch off after a few seconds.
Replace the filter, then press the Pump key to remove the flashing pump icon from the display.
If the instrument should fail during normal operation with a clean filter, the Adjust Flow Fail screen
(see Fig. 15 on p. 21) allows you to adjust the instrument’s flow fail detection point.
To access the Adjust Flow Fail screen from the Main screen:
1. Press the Menu key on the instrument panel.
2. Press numeric key 2 to display the Utilities Menu.
3. Press numeric key 5 to display the Adjust Flow Fail screen:

4. To adjust the value displayed (20 in the sample screen above), press key 3 to scroll left (lower,
more sensitive Flow Fail detection values) or key 6 to scroll right (higher, less sensitive Flow
Fail detection values).
5. If you change your mind during the process and wish to return to the previous setting (20 in
the sample screen shown), press the right-hand soft key to Reject the change.
6. When the contrast displayed is suitable, press the middle soft key to Accept the change and
then return to the Utilities Menu.
NOTICE!
Risk of material damage
 If the filter has drawn in water, replace it immediately to prevent damage to the instrument.
Dirty or discolored filters should also be replaced before you use the instrument again.
