When a leak is detected, return the probe to the area where the leak was
identified and move the probe around slowly until the exact source is
identified. Hold the probe steady until the leak rate stabilizes.
Note:
If the Phoenix Mobilis bar graph fills completely or the instrument display
indicates a flashing 99999, the leak ate has exceeded the detection limit. In
the event of the leak rate being too great, the sensitivity should be adjusted
to a lower level using the up and down keys.
Variation in temperature, humidity or background gas may result in a
constant offset being detected on the Phoenix Mobilis. To reset the zero,
hold the Phoenix Mobilis away from the source of contamination and press
the zero key. Human breath contains moisture and carbon dioxide which
may also affect the readings of the instruments.
