Programming the MEMoryCard XL from the PC with read-write device
Using the card reader which can be purchased separately ( Fig. 34 ), the MEMoryCard XL can
be programmed offline from the PC with “Celsius” without the need for a test chamber being
connected. When you do this, make sure that the contacts on the MEMoryCard XL are point-
ing upwards to the markings on the card reader.

The programme remains stored on the MEMoryCard XL even after it is removed from the
appliance. It can also be overwritten at any time with “Celsius” via the PC.
Logging on the MEMoryCard XL memory card
When a programme sequence from the chip card is running, 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 certain amount of storage space available for logging, depending on the programme
length.
The scanning 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 pro-
gramme lasting up to 135 hours. For programmes lasting longer, the scanning rate is length-
ened to a maximum of 30 min.
For each programme start the logging is restarted, and old log data is overwritten.
