Depends what measurements are taken from the particle counter. For example, for a two channel device, the parameters that consume I/O are marked in bold below:
- 0.5 n/ft3
- 5.0 n/ft3
- 0.5 n/m3
- 5.0 n/m3
- Control Point
- Fail/Status Point
- Flow Point
- Laser Voltage
- Calibration Days Remaining
