5.3.6. DATA LOGGER
The logger of the device can store 12288 events. The registry is in a non-volatile (FLASH) memory, so the registry will retain its contents even in
case of a power failure. The on-board clock of the device is protected against short power-outs, and keeps working for at least 15 days after the
device is switched off. The battery protecting the clock needs at least two hours to be recharged.
The logger operates in two basic ways.
Linear logging, whereby an entry is logged after every time period configured in P35.
Event-controlled logging, whereby an entry is logged after an internal event occurs or condition is fulfilled.
The capacity of the registry allows the following logging times in linear logging mode:
P35 [min] Time of logging Note
0 3..5 hrs. depends on device type and measurement cycle time
1 7..8 days
5 40 days
10 80 days
60 500 days (16 months)
Content of a log:
 entry time (with an accuracy of 1 minute)
 primary measured value (P01)
 level and distance values
 sensor temperature
 output current
 error and status variables
The registry can be erased in parameter P79. See: P79.
