A Quick guide in the Event of Problems
If the reading does not fall below 20.9% after a reasonable purge
time, or in the event that your reading does not pass your expected
level of oxygen, please do the following:
•
Check that the correct purge tubes are used for the quick fit
‘leak tight’ connections in case air is leaking into the instrument.
•
Check the purge gas quality at the source by taking your

100 directly to the source (i.e. gas bottle) to verify
your purge gas quality as well as ensuring that the connections
are ‘leak tight’.
•
Check the cleanliness of the components being welded.
•
Could there be excessive cleaning material or dirt that might
be outgassing?
Note: Excessive oil and grease will outgas and may produce copious quantities
of oxygen until all contamination has been purged.
If you need to reset the monitor, begin by turning it off.
Then press and hold the “Cal” button and the “On” button
simultaneously. Hold both buttons until the word “reset” appears
on the screen.
You will then need to calibrate the monitor at 20.94% and at 0%.
