PLEASE READ THE FOLLOWING:
Human Error is a cause for concern when applied to
check procedures. It exists in every first time set of
analysis procedures. It is therefore essential for
effective and time-efficient servicing that each stage of
every procedure be verified. (For example: When a
symptom is found, or when a symptom appears to have
been cured; the preceding steps should be repeated for
accuracy of analysis.)
