- Select and start your desired flow rate from the User Flow Rates menu.
- If a higher flow rate is required, stop the drive/vent cycle to allow editing of the set up. Slowly increase the drive time to increase the flow rate.
- If air is expelled, decrease the drive time.
- To further optimize the flow rate, increase or decrease the vent time until the highest flow rate is achieved.
Once optimization has been done, remember to save the settings for subsequent sampling events.
