• The data card must be formatted before it can be used to store data. Pro-
ceed as follows:
− Insert data card in the 746 VA Trace Analyzer (see
point ”Inserting data card”).
− Select dialog page ”DATA CARD”. The message
WARNING: Data card not formatted or battery
down appears followed by the inquiry do you want to
[f]ormat, [c]ontinue, [q]uit ?
− Enter f for format. With the inquiry Label of the
Data card ?, you are then prompted to enter a title
for the card. This title can contain max. 20 characters
and will henceforth be displayed under the parameter
Label. On completion of the entry with <ENTER>,
the data card is formatted.
Inserting and removing the data card
The data card can be inserted in the 746 VA Trace Analyzer only in a particular po-
sition (see illustration above). It must be pressed firmly into slot 33 of the 746 VA
Trace Analyzer until the eject button 22 has been pushed out to its full extent.
The data card inserted in slot 33 of the VA Processor is ejected by pressing eject
button 22 and can be removed by hand.
As data cards are sensitive to electrostatic charges, before every
insertion or removal of the data card ensure that you are earthed (first
touch, e.g. the earthed, green metal housing of the 746 VA Trace
Analyzer).
Changing the battery
The battery of the data card has a limited lifetime specified in the enclosed descrip-
tion. Note here that the lifetime of batteries depends on the storage temperature.
The storage temperature of data cards and also spare batteries should thus be as
low as possible (but always less than 25°C).
The date of the next battery change should be written on the label of the data card
(see above). To avoid inadvertent data losses, this should be regarded as the very
latest date for battery change. When convenient, insert the data card in the 746 VA
Trace Analyzer. The data stored on the data card need then only be copied to the
method and/or determination memory of the 746 VA Trace Analyzer if the data card
does not allow a battery change when inserted. Then proceed as follows:
• Change battery as described in the enclosed description.
• Enter new date for the next battery change on the data card (see
point ”Preparing data card”).
• Store date of the battery change on the data card (see point
”Preparing data card”).
