Troubleshooting 

This section describes general troubleshooting procedures, issues, and remedies. 
Before proceeding with further troubleshooting procedures, first verify: 

 

The system has power. 

 

All switches and gas settings are correct. 

 

Column flow rates and pressure settings are correct. 

 

Using a VOM meter, verify the voltage between chassis ground and the test points on the 

bottom of the power supply board are as follows: 

 

+10 volts DC Bias voltage 

 

+2.5 volts DC Feedback voltage 

 

+2.5 volts DC Plasma voltage
