The features in this section are available on models fit-
ted with the optional USB Interface.
Using the USB Port
The USB Interface can be used to upload or download
instrument settings to or from a USB memory stick
(FAT32 formatted). Easy configuration of multiple in-
struments is achieved by copying from one instrument
to another, or by transferring data from the PC configu-
ration software. If the Data Recorder or Profiler options
are fitted, recordings and profile information can also
be transferred via USB memory stick. Refer also to the
USB menu.
USB Memory Stick Folders & Files
When a USB stick is inserted, the instrument looks for,
and if necessary creates the
DEVICE, CONFIG, PRO-
FILE and RECORDER folders. Files must be located
in these folders in order to be used by the instrument.
When preparing to upload files from your PC, ensure
that you save them to the correct folder on the memory
stick.
If the file name already exists, data will be
overwritten.
Note:
To speed up the disk operation, keep the
number of files in these folders to a minimum.
The first recorder log file is named 001-0001.csv. A
new file is created with the first 3 digits incremented
(e.g.
002-0001.csv; 003-0001.csv etc) each time the
data being recorded is changed. The last 4 digits in-
crement (e.g. 001-0002.csv; 001-0003.csv etc) if the
file size reaches 65535 lines, if a recording is stopped
then re-started or if there is a period of >10s without an
alarm when recording from an alarm trigger.
Do not remove the memory stick during data
transfer. Data corruption may result.
During data transfer, normal operations carry
on in the background, but operator access is
denied. Transfer of full memory can take up to
20 minutes. Only begin a transfer when access
to the instrument (e.g. setpoint changes) will
not be required.
