General troubleshooting
This section suggests possible causes of errors and recommends
troubleshooting actions. Keep in mind that the source of apparent detector
problems can actually be the chromatography, or it can involve other system
instruments.
Most detector problems are relatively easy to correct. If, after running the
diagnostic functions applicable to your problem and troubleshooting the
detector, you cannot correct an error condition, contact Waters’ Technical
Service department.
Power surges
Power surges, line spikes, and transient energy sources can adversely affect
detector operations. Be sure that the electrical supply used for the detector is
properly grounded and free from any of these conditions.
