2.4 Data / key card handling (PC cards)
The 796 Titroprocessor can write data onto SRAM storage cards and read
this data in at a later date. It is not possible to use FLASH cards others than
the one delivered with the instrument. The following SRAM cards can be
used as storage or key cards:
• 6.2245.030 Metrohm Data card (capacity 2 MB)
• 6.2245.010 Metrohm Data card (capacity 128 kB)
• Commercial SRAM cards of any capacity (up to 4 MB) with the hardware
format JEIDA 4.0 (68 pin) as well as PCMCIA cards based on them
Because of different file systems PCMCIA cards cannot be used at
the same time for the 796 Titroprocessor and PCs.
When handling data cards with the 796 Titroprocessor the following points
are important:
SRAM card preparation
The following preparations are necessary before data cards (or key cards)
are used for the first time:
• New SRAM cards are supplied with a separately included battery. This
should be inserted in the memory card according to the accompanying
description.
• Data cards can only be inserted in the instrument in the position shown
below. The included label should be attached to the top of the data card.
• The SRAM card battery has a limited lifetime; this is given in the accom-
panying leaflet. In order to avoid accidental loss of data, the date when
the battery is due to be exchanged should be written on the data card
label.
• Before data can be stored on the SRAM card it must be formatted. Pro-
ceed as follows:
• Insert card in the 796 Titroprocessor (see above drawing).
• Select file manager with the softkey [File manager] on the main
page. Change the memory area with the softkey [Change storage],
select 'data card' with the cursor keys and press <ENTER>.
• If an unformatted SRAM card has been inserted a system window
appears on the display. Enter
<f> to format the card.
• A query about the card name is then made. A name with max. 20
characters can be entered; this will now be displayed in the file man-
ager whenever the card is inserted. When the entry has been com-
pleted the data card is formatted with
<Enter>.
