1 Flow rate: 0 = 0.1 cfm (for 0.3µm and 0.5µm sensitivity); 1 = 1.0 cfm (for 0.5µm sensitivity only)
2 Sensitivity: 3 = 0.3 µm minimum sensitivity; 5 = 0.5 µm minimum sensitivity
3 Exhaust location: D = Bottom (down) exhaust; S = Side exhaust
4 Flow measurement: F = with flow measurement; N = without flow measurement
5 Communication: E = Ethernet; S = Serial I/O Options2; A = Analog; W = Wireless3
