Here is the procedure you can follow to adjust the span for each flow (flo B & flo S). Since this is a new flow controller, the existing span can no longer be used. You need a digital flow meter at VENT2 then follow these steps below
1. Make sure you have brass plates in chambers
2. Attached digital flow meter to Vent 2
3. Using the 7000 Utility select the “VALVES” tab and select Valve 1 & Purge
4. Switch over to the “FLOW” tab
5. Adjust the bottom flow to read 10.0 cc on the digital flow meter (the one that is connected to Vent 2) and not the flow display on the screen
6. Once you adjusted it to 10.0cc wait for 30 seconds for it to stabilize and adjust if needed.
7. Switch over to the “FLOW” tab, under FLO-B you will see a box labeled “SPAN” adjust this number accordingly so that the flow on the screen matches the flow coming from the digital flow meter
8. Under the “FLO-T” area (this is FLO-S), adjust the span here to match the FLO-B reading
