5.4 Diagnostic tests
5.4.1 General
The 732 IC Detector and 733 IC Separation Center are very precise and
dependable instruments. Thanks to their rugged construction, it is
highly unlikely that external mechanical or electrical influences will have
any adverse effect on their functions.
Although a fault in the instruments can not be excluded with certainty,
the possibility is greater that malfunctions are caused by wrong opera-
tion or handling, through improper connections and the operation with
third-party devices.
Whatever the case, it is always advisable to localize the fault with the
diagnostic tests, which can be performed quickly and simply. The cus-
tomer need call Metrohm service only when the instrument really has a
fault. Further, he can use the results of the specific diagnostic function
to provide the service engineer with much more precise information.
In the case of inquiries, always quote the serial number on model plate
10 10 of the 732 IC Detector (see Fig. 3) or on model plate 47 47 of the 733
IC Separation Center (see Fig. 5), program version (see section 4.4.2)
and if applicable the error message.
Procedure
The diagnostic menu listed in section 5.4.2 shows all components for
which detailed instructions (diagnostic steps) are available for checking
the functionality.
In the case of a possible malfunction, we advise you to perform either
the corresponding diagnostic step or all diagnostic steps as a routine
step on the instrument.
The reactions of the instruments to the instructions must be compared
with the descriptions in the diagnostic step. If the instruments do not
show the expected reaction ("No" case), the appropriate diagnostic
step must be repeated to exclude operating errors. However, it is highly
probable that repeated wrong reactions indicate a malfunction.
Instruments needed:
Necessary only if RS232 or remote should be checked:
• 3.496.8510 Test plug (at ‘"Remote" socket)
• 3.496.8480 Test plug (at "RS 232" socket)
