3. Programme the chamber on the computer. The chosen settings are written and stored on
the card.
Via the “Celsius“ software, the MEMoryCard XL can be provided with write protection.
The programme on the card can then no longer be altered on the controller.
Programme alterations via the controller are only possible if the write protection has
been disabled from the computer with the “Celsius“ software.
Programming the MEMoryCard XL from the computer with the read-write device
Using the read-write device which can be purchased separately ( Fig. 33 ), the MEMoryCard XL
can be programmed offline on the computer with “Celsius“ without the need for a constant
climate chamber being connected. When you do this, make sure that the contacts on the
MEMoryCard XL are pointing upwards to the markings on the read-write device.

The programme remains stored on the MEMory-Card XL even after it is removed from
the appliance. It can also be overwritten at any time with “Celsius“ via the computer.
Logging on the MEMoryCard XL
During a programme sequence running from the chip card, the humidity and temperature
setpoints are continually logged on the memory card. These can be read in via “Celsius” after
the programme is finished and printed out. This is described in the “Celsius“ user manual.
There is a certain amount of storage space available for logging, depending on the pro-
gramme duration. The scanning rate is set automatically by the controller, depending on the
programme duration.
The actual value can be logged on the MEMoryCard XL at one minute intervals
for a programme lasting up to 135 hours. For programmes lasting longer, the scanning rate is
lengthened to a maximum of 30 min.
At each programme start, the logging is restarted and old log data is overwritten.
