OPERATION MSA
28 ALTAIR 5 - Operating Manual
3.2.1 Sampling Safety Test
This test is only available for instruments that are equipped with an integral pump.
Upon startup, an alarm (visual, audible and vibrating) is triggered and the
customer is prompted to block the pumps/sampling system of the instrument
within 30 seconds.
When the instrument detects a pump flow block, it will display a PASS message.
The startup sequence will be resumed.
If the instrument does not detect a pump flow block, it will display an error
message.
The instrument will shut off after the customer acknowledges this message by
pressing the
button.
Check your sampling system if this occurs and contact MSA as needed.
Users can check the operation of the sampling system anytime during operation
by blocking the sampling system to generate a pump alarm.
Warning!
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.
