Chapter 2 Trouble-shooting
Chapter 2. Trouble-shooting
This chapter helps you determine the cause of a given fault and possibly quarantine the faulty component or
subassembly; in which case the requisite actions are specified.
When contacting Chopin Technologies After-Sales, always state the serial number of the instrument.
1. Method
■
Known faults are classified as:
- A. Error messages
- B. Other faults .
❏
Other abnormal events can occur and it is up to the repairman to
resolve the problem through analysis and comparisons. Simplified
interconnection diagrams are provided in §
3. of this chapter, which
may help the trouble-shooting process.
Naturally, in case of difficulty or if in doubt, Chopin's technical ser-
vices are at your disposal to try and resolve the problem, by tele-
phone, fax or e-mail.
Failing which, the instrument will have to be returned to CHOPIN
Technologies for fixing and repairs.
■
Before starting to trouble-shoot, be sure to record all relevant
information.
❏
In the event of an abnormal result, checking the control chart (if it
exists) could provide an immediate explanation (the case of a per-
manent deviation for instance).
❏
We recommend you consult the history of settings and errors:
"History" menu.
❏
Irrespective of the fault, we recommend carefully noting down the
conditions in which it occurred.
If a fault occurs during a test, it is advisable whenever possible to
keep a record of the curve charts and test results.
