Once gas readings are displayed, plug the free end of the sampling line or
probe.

PUMP ERROR
When the pump inlet, sample line or probe is blocked, the pump alarm must
activate.
If the alarm does not activate:
a.
b.
Do not use the pump, sample line, or probe unless the pump alarm
activates when the flow is blocked. Lack of an alarm is an indication that
a sample may not be drawn to the sensors, which could cause
inaccurate readings.
Failure to follow the above can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid
surface. If liquid is drawn into the instrument, readings will be inaccurate
and instrument could be damaged. We recommend the use of an MSA
sample probe containing a special membrane filter, permeable to gas
but impermeable to water, to prevent such an occurrence.
