7.2.2 USB Data Export
The Landmark Graphic MkII contains an internal log of the last 24 hours of
temperature reading for each IO card channel fitted.
The USB function menu allows the operator to export this internal log as a
CSV file to a USB storage device.
NOTES
Only the final processed temperature which includes averaging/peak
picking etc is stored (ie, the value shown on the display).
The internal log is volatile, which means that it is lost if the unit is reset or
power is disconnected.
To export the log, follow the procedure:
1) Insert a suitable USB storage device into the Landmark Graphic MkII
USB port
2) Enter the code to access the main menu.
3) If the USB device is found, the USB function button will be shown. Click
on it to access the USB functions menu.
4) From the USB function menu, select ‘Export Data’ (See Fig. 7-3).
5) Set the
Length adjuster to select how much historic data s to be
exported. e.g. 5m exports the last 5 minutes of recorded data, 8h
exports the last 8 hours of recorded data.
6) The Available line shows how long the internal log currently is. If the
unit has been recently rebooted, this will show the time since the unit
started. Once the log is full, this will show 24 hours.
7) Adjust the Interval setting to select the resolution of the exported
data. The internal log stores values every 100 ms, so this is the smallest
selectable interval. The interval is adjustable up to 60 seconds.
e.g. a 1 hour length log with interval 100 ms will export 36000 data
points per channel.
A 24 hour length log with interval 30 s export 960 data points per
channel.
8) Select the Save to USB option to start the export process.
9) The more data to export, the longer the export process will take, wait
for the Please Wait screen to exit before removing the USB drive.
Once the export is complete, the Landmark Graphic MkII will return to
the main menu.
