Troubleshooting Guide
Introduction to Troubleshooting
Good troubleshooting skills are learned by using a logical, step-by-step approach
to problem solving. The first step in the process is understanding normal
instrument operation and preventative maintenance. A good working knowledge of
the instrument is essential for identifying and resolving operational problems.
Logical troubleshooting may be divided into three steps:
1. Problem Identification
2. Problem Isolation
3. Corrective Action
Step 1, the problem identification step, is not only identifying what is wrong but
also noting what is right. The investigation should identify the problem area and
eliminate areas that are working correctly. Once this is done, the troubleshooting
process moves quickly to the next step.
Step 2, Problem Isolation, further classifies the problem. Instrument problems are
generally divided into three categories:
Hardware —
component related
Software —
computer program related
Measurement —
related to sample analysis
Typically, hardware and software problems are corrected by an authorized service
representative. Measurement problems are generally operator correctable. This
category is further subdivided into problems related to Sample Handling,
Maintenance or Calibration.
Step 3, Corrective Action, involves taking appropriate action to correct the
problem. If the operator can correct the problem, with or without technical
assistance, normal operation can quickly resume.
This Troubleshooting Guide is designed to enhance the troubleshooting process by
providing information to assist in problem identification, isolation and corrective
action.
NOTE:
Generally, conditions that are instrument- or reagent-related will occur on
all samples, including controls. Therefore, it is important to confirm
instrument performance by rerunning controls and/or additional patient
specimens.
