7.3 Error messages
7.3.1 General information on error messages
The occurrence of errors of all types during operation of the 746 VA Trace Analyzer
is indicated by error messages, which normally appear in a separate window and
have the following structure:
The error message first provides information for error identification (error class
and error number), this is followed by a short error description. You will find fur-
ther details on the error messages, their possible causes and the procedure for
their rectification in the alphabetical list of error messages in section 7.3.2.
Error messages arising from errors in the method test (
on the
”MONITORING” page) or in the syntax test ( on the ”CALCU-
LATION” page) appear in the ERROR WINDOW in which the last 18 error messages
are always stored. In addition to the normal error messages, the error messages
displayed in the ERROR WINDOW contain the date and time of occurrence of the er-
ror. The 4-line window can be enlarged by pressing the softkey so that all
stored error messages can be read.
In the ”Exit” column of the list of error messages, you will find abbreviations de-
scribing how you should acknowledge the error message and how an ongoing
program behaves after it has been exited. In automatic series determinations with
Auto.batch = on , the errors are automatically acknowledged after a wait time of
10 s if at all possible.
Should you require the support of your Metrohm agency in the case of malfunc-
tions or faults which can not be rectified or explained, proceed as follows:
• Copy the questionable determination to a data card or with the aid of the PC
program ”VA Back Up” or "VA Database" to a diskette and send the card or
diskette together with a description of the fault to the Metrohm agency, or
• Load the questionable determination into the working storage. Print out the
full report ” Report Full ”, the method report ” Report MethSpc ”, the desired
substance or segment curves and possibly the list of measured points and
send these together with a description of the fault to the Metrohm agency.
