Troubleshooting
The following is a list of the most common problems that can occur when using the
PFPD, along with their most probable causes and corresponding corrective actions.
Each symptom potentially may be caused by more than one problem. The probable
causes of each symptom are listed in order of increasing seriousness. Each correc-
tive action has been discussed earlier in this manual, under either an installation,
operation, or maintenance procedure. Before using this guide, please become
thoroughly familiar with the operation and maintenance information contained in
previous chapters.
If none of the following corrective actions correct the problem(s) being experi-
enced, contact OI Analytical’s Customer Service Department at (800) 336-1911 or
(409) 690-1711 with the following three printouts available:
1. WinPulse screen showing a peak emission signal: To capture a peak re-
sponse during a chromatographic run, activate one of the two hold buttons on
the right of the main screen at the moment that the emission signal reaches its
maximum value. To save the screen:
• Press [Alt][Print Screen] on the PC’s keyboard
• Open the Paint program (usually found in the Accessories directory of
Windows 95).
• Go to the Edit menu and select Paste.
• Save the captured screen to a file, and print out a copy of the captured
screen.
2. WinPulse parameter values: To obtain this, go to the File menu in WinPulse
and select Print; or click on the
button at the top of the main screen
3. Chromatogram: If a PC-based program, such as Agilent ChemStation, is
being used to generate the chromatogram, a printout can be obtained using the
same screen capture sequence described for capturing a WinPulse screen.
