If on the contrary the reconstitution fails, it means that the temperature data previously stored are, at least
in part, cannot be retrieved. In this case the alarm starts and the fixed mask below appears:
System failure:
LOST PARAMETERS
Even though the Datalogger keeps on sampling the temperatures, the management of the stored data is no
more ensured, and so it is advisable to contact Carel.
Furthermore, there is the case in which the instrument shows some irregularities of the Clock during the
normal operation. In this case a "virtual clock" begins functioning and ensures, as far as possible, the data
acquisition and storage. The user is informed on this possibility by the blinking of the LED coupled with the
"clock" button, in addition to the usual alarm procedure. The mask revealing this alarm is:
System failure:
CLOCK ERROR
In the presence of this mask, it is advisable to insert the date again (see "Enter button - Parameter
Modification Mode"). If this mask persists, contact Carel for assistance.
Anyway, the virtual clock is activated.
The temperature storing
The temperature data are stored together with the date and hour and further information that appear with the
stored temperature. As regards the encoding of this information, see table 2.
Note that a selection of the sampling time lower than 14 minutes (also for a time period) does not ensure any
more the data conservation for the period established by the law (one year).
