This chapter describes several tests that can shorten the time for troubleshooting. Most
problems require the use of two or more tests to determine the cause.
If a problem is isolated to a load cell, it may not mean the load cell is the damaged
component. Mechanical imbalances and system piping stress (lack of piping flexures,
pressure hoses draped over, pipes etc.) can make a load cell or Weight Processor seem to
be the problem.
If you are in doubt as to how to resolve a problem or if you need assistance, review
