Is the storage card inserted when switching on the device or is it being inserted within stand-by mode

and subsequently accepted, the LCD shows for about 3 seconds card size and version. Afterwards the

interval and free storage time will be displayed. With the keys "+" and "-" the data storage interval can

be changed during this indication and the free storage times refresh. With an inserted and installed

data storage card all measured values will automatically be saved on the storage card.

The device will only accept a data storage card if all data have been deleted or if the card

already has been used inside the same device without changing the number or kind of

sensors. A not accepted data storage card does not show free storage space.

It is not possible to use a data storage card from an other device if this card is not empty.

Already existing data from an other device with a different serial number have to be deleted,

before new data from the actual device can be stored on this card.

The storage card can be deleted in two different ways. On the one hand with the adequate key

combination via the key pad, see chapter 5.4. Key functions in the standby mode, or on the other hand

via the Windows software, or an adequate control command using the HyperTerminal, see RS-232 in

chapter 5.4.

The measurement does not start if the storage card is not accepted. Please check if the write

protection of the data storage card is being activated. The write protection can be activated

respectively deactivated with slider next to the cards′ battery case.

If no data storage card is being used the LCD shows after switching on the device:

?NO MEMOCARD“

Starting a measurement and additional warning signal (beep-tone) resounds.

Data preservation and storage times

A buffer battery preserves the data on the storage card. If the storage card is inserted inside the

device, the power supply happens via the device. Before changing the battery please read out all the

data otherwise data loss might happen.

Having the message:

?PLEASE REPLACE

MEMOCARD“

means that the battery of the storage card has to be changed.

There are data storage cards with various storage capacity, beginning at 256 KB up to 4 MB. The

storage interval can be selected stepwise. Transcending the stated storage time leads to overwriting of

the oldest values. The card remains ready-to-operate.
