Logging - Hanna Instruments HI2400 Instruction Manual

LOGGING

This function allows the user to log DO (in ppm or %) together with
temperature automatically, for long periods of time. All logged data can
be stored into a PC through the USB port.
The memory used for storing the logged data is divided in 32 pages.
The capacity of each page is 250 samples. The lot number goes from
1 to 100. The maximum capacity of the log memory is 8000 samples.
Each time a new lot starts, it automatically starts from a new page. When
the samples collected for a single lot reach the limit (8000 samples) or
all memory pages are occupied, the meter stops logging automatically.
The appropriate logging interval can be set between 5, 10, 30 seconds or
1, 2, 5, 10, 15, 30, 60, 120, 180 minutes (see SETUP section for details).
LOGGING THE CURRENT DATA
To start the Auto LOG mode press LOG while in
measurement mode.
When the selected interval is reached the instrument will display the
current lot number on the primary LCD line, the record number on the
secondary LCD line and the LOG tag ( see example below: Lot 15 record 22)
followed by the number of free records on the corresponding memory
space.
If there are less than 6 memory locations remaining, the record number
and "Lo" message will be displayed to alert the user.
To stop the Auto LOG mode press LOG again. The "LOG" tag will be
cleared.
