Atmospheric Technology

Ch.2 MFC Set Point

The sampling flow rate for the Channel 2 cartridge is specified in this box

Flow Leak Limit

The flow leak limit is the maximum flow rate that is allowed for a cartridge to pass
either manual or automatic leak check. This value has the same units as the flow
rate.

Flow Tolerance

The cartridge flow rate is continuously monitored during sampling. If the flow rate
specified in Ch.1 MFC or Ch.2 MFC Set Point box is outside this tolerance, an error
status for flow tolerance will be generated. This value has the same units as the
flow rate.

Cycled Schedule

The Cycled Schedule value specifies the time interval in days between schedules.
This allows the operator to schedule repeated samples at a set interval automatically
(i.e. sampling repeated every 6 days if set to 6). The value must be greater than 1 to
be applied.

Purge Time

Purge time specifies the purging time in minutes of the inlet line and inlet manifold
before sampling the cartridges.

Data Write Interval

The Data Write Interval specifies the time interval for recording canister pressure
and cartridge flow rate data. The minimum time interval is 5 minutes.
