Measured Data Storage - Hach ORBISPHERE G1100 User Manual

6.3 Measured data storage

There is one measurement file which contains the data generated by the measurement cycle.
The measurement file is updated in volatile memory, and regularly copied in non-volatile
memory (file back-up). At start up, the measurement file in volatile memory is updated with the
file from the non-volatile memory.
Note: Data stored in volatile
memory are lost when instrument
is off, non-volatile memory is
permanent. In case of an
accidental power off event, the
instrument resumes
measurement storage after the
last measurement stored in flash.
This dialog box allows adjustment of the parameters for
recording and storing measurements.
Storage mode selection:
•
No storage
•
Store once: When the volatile memory is full (1,000
•
positions), the recording of measurement stops.
Rolling buffer: When the volatile memory is full, the
•
latest measurement set replaces the oldest one
continuously (first-in, first-out)
RAM time (volatile memory): Delay in seconds between
•
two recordings of measured data.
FLASH time (non-volatile memory): Delay in seconds
•
between two data file transfers from volatile memory into
non-volatile memory. The last data file erases the previous
one. This field is only available if the Auto save in flash box
is checked.
Save in flash now: Press this button to store measurement
•
data in flash (non-volatile memory) immediately. After
pressing this button, press OK to initiate the process. A
warning screen appears informing you that the operation
can take up to 30 seconds. Press Yes to continue with the
process, or No to abort.
Auto save in flash: Check this box to save measurements
•
in flash (non-volatile memory) automatically.
Measurements are saved at regular time intervals as
defined in the FLASH time box.
Purge data: Clear all data in the volatile and non-volatile
•
memories
Start logging measurement: Store once mode. Starts and
•
stops the measurement recording session. Measurement
recording is stopped when the buffer is full.
Open data: Opens a table showing the measured values
•
which are stored in the volatile memory (RAM).
Use the scroll bar at the right to move to another data
range (the id range will be shown in the title bar).
The page number being viewed and the total number of
pages are shown at the bottom (page 1 of 13 in the
example left).
Use the keys at the bottom to move directly to the first
page, previous page, next page or last page.
