The CG1100 has a flow control system used to maintain the flow rate set in
 the configurator software. The accuracy of the oxygen analyzer readings are
flow-dependent. Maintaining the same flow rate during calibration ensures
NOTE
the accuracy of the oxygen analyzer during manual operation after the unit is
calibrated.
For Example: If the sample flow is set to 100 sccm, a delta pressure of 25 torr (10 inches of
water) must be present from the inlet port to the outlet port for the flow control system to func-
tion properly.
