Database

Problem

Remedy

Curve is not represented

Do you have the quantities selected in the curve
in your data set? Check the quantities in the
curve: "Right mouse button in the curve window,
Properties, Data".

Do you have a measuring point list in your data
set? For curve representation you have to send
a measuring point list from your analytical de-
vice.

"Empty" data sets

You may have empty data sets, if your analytical
device works with software handshake and the
datalogger with hardware handshake.

No raw reports

Check in the datalogger if you stored the raw re-
ports from the corresponding analytical device:
"Device window, Properties, Reports".

Check in the database if all raw reports are dis-
played: Select the raw report window, right
mouse button and select "Properties".

No results in the determina-
tions table

Your raw report contains results which are not
displayed in the determinations table.
Make sure that the analytical device sends a
"calc" report to Vesuv.

Re-evaluation is not possible
or difficult

Graphical re-evaluation is only possible for DET
and MET modes.

If you have problems with the parallel evaluation,
switching on or off of the setting "Curve, Proper-
ties, Data, Smooth" may help.
You may also vary the Smoothing factors X and
Y, see page 82.

Slow

Compress your database from time to time.

Close all the windows which you don't need:
Statistics, Endpoints, Variables+Formulas etc.

Reduce the number of visible columns in the
determinations table (menu item "View, Proper-
ties").

Add enough RAM:
At least 64 MB.
