This chapter contains Lubrication and troubleshooting procedures that must be accomplished by the operator.
SECTION I. OPERATOR LUBRICATION
Lubrication not required.
SECTION II. OPERATOR TROUBLESHOOTING
3.1. OPERATOR TROUBLESHOOTING.
Operator troubleshooting and maintenance for the WQAS-PM equipment is limited to checking the power-setup for the
Spectrophotometer (paragraph 2.6.2.3) and to those actions required in the PMCS (table 2-1). Apart from equipment
failures and errors in technique, many problems you might encounter when analyzing water samples using the WQAS
will be related to the chemistry involved. An example is interference by other chemicals in the sample. A detailed
discussion of the chemistry and alternative methods are beyond the scope of this manual and the capabilities of the
WQAS-PM. Unresolved problems should be referred to your supervisor.
The Malfunction Symptom Index below lists common symptoms that might be corrected by operator maintenance. Table
3-1 is a troubleshooting logic tree which can be used to isolate faults for replacement or for referral to unit maintenance.
