Registration of Measurements

The device starts to register measurements immediately after the power
supply is switched on. This data will be stored together with timestamps
and device status in the registration period buffer according to the selected
parameters (the factory settings will be used when the unit starts for the
first time).
Setting the time during measurement
If the time is set backwards during measurement, all registration period
buffer entries with a timestamp after the newly set time are marked as inva-
lid and they are then no longer accessible via data retrieval. If the time is
set forwards, all registration periods in the skipped period are treated like
entries during „power down" condition and are displayed as „--------„.
Memory overflow:
Once the memory capacity of the registration period storage has been ex-
hausted, the oldest entries will be automatically overwritten (due to the
storage technology used this affects at least one sector = 64kByte in the
buffer).
Power failures:
Should a power failure include the end of a registration period, then all reg-
istered measurements up that point in time will be stored at the end of the
first incomplete registration period. This period will then be marked as in-
complete.
Registration periods without power:
Should the device not have been supplied with power for one or more com-
plete registration periods, then these are called „power down". These regis-
tration periods do not use memory. If values are requested from these
periods for display purposes, they are shown as "--------".
Storage during programming:
The device continues to register measurements during the period of pro-
gramming without interruption. Once programming is terminated, it checks
which parameters have been modified. If the storage allocation or the regis-
tration period length was altered, all of the registration period storage area
will be cleared.
