performed via software (with a previous overwrite warning).
Stop settings:
The logger stop can be performed by simply pressing a button (start/stop button) or
by using a Reed contact (option). This function can be disabled by unchecking the
appropriate boxes.
The other specifications allow:
the use of the internal memory as circular memory (the oldest records are
overwritten when the memory is full)
the stop as soon as the memory is completely filled (60,000 records)
the stop at a preset time (date and time)
the stop after a preset period *)
the stop after a preset number of records *)
The specifications marked with an asterisk *) limit the storage capacity to a record number less than
60000
When entering a stop time, make sure that it is not less than the logger time or less
than the start time. The stop time should not be reached at the time when the data
have completely been transferred to the logger, otherwise the program will not react
to the entry of the stop time. A verification only takes place during entry.
Measuring interval:
The entry a measuring interval ranges from one second is to 86400 seconds and is
presented in the format hours / minutes / seconds (hh: mm: ss). When 86400
seconds (24 hours) are reached, one day 00:00:00 appears.
Just make sure that the measuring intervals do not exceed a value of approx. 3.5 hours with the
planned and full utilization of the 60,000 records available since the lifetime of the battery would be
reduced compared to the resulting lapse of time of nearly two years.
Limit values:
The minimum and maximum values can be predefined in the category "Limit values".
The logger emits an alarm if the upper or lower limit values are exceeded.
