Troubleshooting
The first and most important aspect of troubleshooting anything is to be
systematic. Note where you have looked and what you found.
Look first for the obvious.
Make a physical inspection of the entire facility. Are all necessary
connections properly made? Do you see any signs of obvious damage within
the equipment?
Is the AC power ‘ON’ to the site and the equipment? (Check fuses and circuit
breakers if necessary.)
Are all the switches in the correct operating position?
Is the input signal present and at the correct level?
Check display readings for presence of forward and reflected power and DC
supply levels.
The following flowcharts are an aid in determining the fault if some aspect of the
system is not operating.
