Data Logger Function
This series of devices has the possibility of recording values in GLP format on the instrument's internal
memory.
•
The instrument can save up to 1000 data in total. Once the memory is finished, the values are NOT
overwritten. In measure mode, the number of data stored for that parameter appears next to the
M+
icon.
•
It is possible to recall and consult the values on the display or download them to a PC using the
appropriate software.
•
If you have the possibility to work directly connected to the PC, the data are automatically saved on
the software without having memory limitations.
•
Recordings can be acquired
manually
(MANUAL) or
automatically at preset frequencies
(HOURS -
MINUTES).
