Marking a reading with an inspection mark
When you press the START/Mark button, the next reading taken
by the USRIC-8 will be identied in the downloaded data with
an inspection mark. If the Allow stopping with the Stop button
feature is congured, a mark will also be registered when you press
the STOP button, but do not complete the process of stopping the
recorder.
When does the USRIC-8 stop recording?
Automatically
e USRIC-8 stops recording temperature when the maximum
number of readings specied during conguration has been reached.
Your unit may also stop when inserted into a USB socket. is is a
factory set option which cannot be changed during conguration
of the unit with LogTag Analyzer. Your distributor can supply more
information about this option.
Manually
You can set up a USRIC-8 so it can be stopped with the STOP
button. is feature is useful when you take the recorder out of a
shipment and don’t want to falsify the statistics with readings taken
after the shipment completion. You can enable stopping in the
Advanced Options dialogue during conguration. When enabled,
following sequence will stop the unit:
• Press and hold the STOP button. For the next 4 seconds both
LED’s will blink simultaneously.
• When the LED’s start blinking more rapidly release the button.
e recorder will now stop taking readings and cannot be re-
started.
• If you change your mind half way during the process, simply keep
holding the button until all LEDs have stopped blinking. Instead
of stopping, an inspection mark will be recorded against the next
temperature reading taken.
Plugging the USRIC-8 into a USB port
What happens when you plug the USRIC-8 into a USB port
depends on the Operating System of the computer, the settings
made during conguration and whether or not LogTag Analyzer is
running.
• If you have congured the USRIC-8 to Generate les, PDF, CSV
or LTD les will be created every time you plug the recorder into
the USB port. is will be indicated by the green OK LED being
permanently on.
Once nished, the green OK LED will blink every second, twice
in quick succession, to indicate these les can now be accessed.
• If you have disabled le generation, the USRIC-8‘s green OK
LED will blink once every second.
As part of the process up to four drivers will be installed. ese
drivers are part of the Operating System and will typically not
require administrator privileges for your computer.
1. Mass Storage Device
2. LogTag Mass Storage USB Device
ese two devices are required so you can access the data les in
the same way as a USB memory stick. ese drivers will not be
installed if the USRIC-8 is congured not to generate les. not
3. USB Input Device (HID)
is device is used for communication to LogTag Analyzer and
its driver will always be installed, even if LogTag Analyzer is not
present on the PC.
4. USB Composite Device
Which of these drivers will be installed depends on the USRIC-8’s
conguration.
While a USRIC-8 is plugged into USB, no temperature readings
are taken. e graph will display a gap and the data list will indicate
“paused”. is also applies when the recorder is connected to a USB
power supply.
Accessing the files
If les are generated, a new storage device or mounted device will
appear. e device name will be created from the serial number of
the USRIC-8. You can access the les by browsing to the newly
created drive and double-clicking the PDF, CSV or LTD les. For
PDF les you need Adobe Acrobat Reader or a similar PDF viewer.
To open the LTD le you need to install the free LogTag Analyzer
software. CSV les can be opened with a text editor, or imported
into a spreadsheet program such as MS ExcelTM.
e le names contain information about the recorded data, which is
detailed in the section about “Interpreting the data” on page 8.
If a device only has pre-start readings, PDF and CSV les will not be
created.
e les created by the USRIC-8 are not automatically copied to a
permanent storage volume on your computer. If you wish to retain
the les you need to manually copy them to a location such as your
Documents folder.
Unplugging
You can unplug a USRIC-8 at any time; there is no need to stop the
device via the shortcut menu in the notication area on the taskbar.
If you plug a unit into a USB port during a start delay, the delay
period will re-start when the unit is unplugged. You will see the
start and delay signals indicated by the LED’s. e delay will also be
restarted if you press the START/Mark button during the delay
period.
You may see the start signal if you have congured a time start, but
have left the unit plugged in beyond the start time of the USRIC-8.
