*maximum dependent on operating environment

SS-4
Pump Drive set to 40%
Flow rate: 0-2000 ml/min
One SS-4 should be connected to an empty cage to act as Baseline (BL)

MUX
Operating mode = DIGITAL 01-08

FMS
  - Flow control		Closed, 100p
  - Flow set			250 ml/min
  - Gas Units 			BP Compen %
  - Flow range			0-500 ml/min
  - Analog 1			BP 90-110
  - Analog 2			Massflow range as set
 Note: FMS flow rate should be ½ of the SS4 flow rates
SS4: 500 ml/min
FMS: 250 ml/min
Can sample up to 80% if we choose to sample faster
