Auto Balance the Flow Rate
Note: All analyzers should be in Monitor except for the one being Auto Balanced.
Perform an Auto Balance for the following reasons:
When a line length is changed
l
If end-of-line filters are replaced
l
The gas family changes
l
When a new Chemcassette™ is installed
l
When analyzers are added to a Vertex M rack
l
To perform an Auto Balance:
1. Make sure Chemcassette™ is installed.
2. Set analyzer to idle (not monitoring). See "Run Time Options" on page 101 for more
information on the procedure.
3. If not already open, touch Main Screen, Menu, Calibration. The Flow Diagnostic window
opens.
4. Choose analyzer from the selection pad in the upper right-hand corner.
5. Touch the Auto Balance function button. Vertex M will characterize the flow between
minimum and maximum. This data will be used to set the flow to 180 cc/min. when the
analyzer is returned to monitor mode. Autobalancing takes approximately 130 seconds to
complete.
6. If required, repeat for other analyzers.
Note: If Vertex M cannot adjust the flow to the proper range (150 to 210 cc per minute at worst
case condition) consult Honeywell service.
