9. TROUBLESHOOTING

9.1 Common 

Conditions

Your XFM Digital Mass Flow Meter was thoroughly checked at numerous quality
control points during and after manufacturing and assembly operations. It was cal-
ibrated according to your desired flow and pressure conditions for a given gas or
a mixture of gases.

It was carefully packed to prevent damage during shipment. Should you feel that
the instrument is not functioning properly, please check for the following common
conditions first:

Are all cables connected correctly? Are there any leaks in the installation? Is the
power supply correctly selected according to requirements? When several meters
are used a power supply with appropriate current rating should be selected.

Were the connector pinouts matched properly? When interchanging with other
manufacturers' equipment, cables and connectors must be carefully wired for cor-
rect pin configurations. Is the pressure differential across the instrument sufficient?
