12.1 Error messages
Error messages are accompanied by the name of the instrument module in
which the fault has occurred. In addition, each error message is provided
with a number so that it is easier to find the corresponding error message in
the following list.
A/D CONV
A/D CONV 1: XX not corr. sensor for DEVICES and METHOD
In the method being carried out a sensor has been laid down which does
not match the current entry on the dialog page 'Devices & Manual Control'.
Check whether the correct sensor is being used. If necessary bring the entry
up to date (<MAN CONTROL> key). If the comparison of the sensor
names is not required this can be switched off by completely deleting the
entry.
A/D CONV 2: X: check temperature sensor
Either no temperature sensor has been connected to the sensor interface X,
or it may have a fault.
A/D CONV 3: interface X busy
• The sensor to be accessed is currently being used for an actual deter-
mination. Wait until this has been completed.
• A method in progress is trying to access a sensor which is currently be-
ing used for a manual measurement. This causes the determination to
be interrupted ('HOLD'). It can be resumed by pressing the <HOLD /
CONT> key as soon as the affected sensor is available again.
A/D CONV 4: interface X: unexpected error
A fault has occurred which cannot be specified more closely. Please con-
tact the service department of your local Metrohm agency and tell them the
error message number.
A/D CONV 5: interface X not present
An attempt has been made to access a sensor interface which has not been
installed. Check the method.
