To start the data logging function, press and hold LOGG button for 2 seconds, the display will
show LOGG and free memory space will be displayed as a percentage value (from 100 to 0). The
memory stores data on measured value, its unit, date and time.
LOGG will blink at intervals equal to the set sampling period, indicating when the measurement is
taken.
When the memory is full, then the percentage value shown is 0 and a double beep is generated to
indicate ending the data logging process. If data logging mode is activated when the meter
memory is full, the meter after 2 seconds will exit this mode and LOGG symbol will disappear - af-
ter that a double beep is generated.
To stop the data logging function, press and hold LOGG button for 2 seconds, the meter will return
to the normal operation mode, data logging may be started from the beginning.
As data is logged in a separate memory, different than a single measurement, the user may save
single measurement results. This may be done by pressing MEM/ENTER button. In such case, the
display apart from LOGG symbol will additionally show MEM, and instead of the percentage value
of free memory space, the device will display the number of memory cell where the measurement
is saved.
To clear the memory of the meter, turn the meter ON while holding down LOGG button. The main
display will show and the percentage value field will show the amount of free space that will
change from 0 to 100 % when erasing progresses. After erasing the memory, the meter returns to
the measurement mode.
Logged data may be read only with the PC software provided with the meter.
