Performing User Recalibrations and Checks
Check or recalibrate the sheath flow as part of your routing maintenance to
ensure ±2 percent accuracy of sheath flow rate. Full details of the sheath
flow calibration are given in Chapter 5, Performing a User Calibration.
The differential pressure sensor has some sensitivity to temperature
therefore the sensor be zeroed from time-to-time as well as before you
perform an impactor calibration.

your routine maintenance. Full details of the sheath flow calibration are
given in Chapter 5, Performing a User Calibration.
