Disconnecting the OM-USB-5203 from the computer
You don't need to shut down your computer to disconnect the OM-USB-5203. Refer to the instructions below
when disconnecting the OM-USB-5203 from your computer's USB port.
In most cases, the OM-USB-5203 shows up as a mass storage device in Windows. To avoid losing data, safely
remove the device from Windows before disconnecting it by using the
Eject
option or the
Safely Remove
Hardware
icon. Windows displays a notification telling you it's safe to disconnect the device.
Transferring binary data after a logging session
Data is stored on the memory card in binary files. After logging measurements, you can transfer the files to your
computer by reconnecting the OM-USB-5203 to a USB port on your computer or by removing the
CompactFlash card from the OM-USB-5203 and using a card reader connected to your computer.
Note that when installed with firmware version 3 and later the OM-USB-5203 appears as a Mass Storage
Device when connected to a USB port on your computer, so you can copy files using Windows Explorer.
Converting binary data after a logging session
If your OM-USB-5203 is connected to a USB port on your computer, you can use InstaCal or TracerDAQ to
convert the files on the CompactFlash card to .CSV format for use in Microsoft Excel files, or to .TXT format
for use in other applications.
If you transferred binary files to your computer hard drive or removed the CompactFlash card from the device
and are using a card reader connected to a computer, use TracerDAQ to import the files and save them as .CSV
or.TXT format. InstaCal can only convert files when the CompactFlash card is in a device connected to a
computer.
