Installing the OM-USB-5203
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Omega Engineering immediately by phone, fax, or e-mail.
Installing the software
Refer to the
Software User's Guide
for instructions on installing
the software on the CD. This booklet is
available in PDF at
www.omega.com/manuals/manualpdf/M4803.pdf
Installing the hardware
To connect the OM-USB-5203 to your system, turn on your computer and connect the USB cable to an
available USB port on the computer or to an external USB hub connected to the computer. Connect the other
end of the USB cable to the USB connector on the device. No external power is required. A green
Status
LED
turns on when power is applied.
When you connect the device for the first time, a
Found New Hardware
dialog opens when the operating
system detects the device. The dialog closes after the device is installed.
Configuring the hardware
All hardware configuration options on the OM-USB-5203 are software-selectable. Use InstaCal to set the
thermocouple type for each channel. Configuration options are stored on an isolated microcontroller in
EEPROM – which is non-volatile memory on the OM-USB-5203 – and are loaded on power-up. The factory
default configuration is
Type J
thermocouple.
Warm up
Allow the OM-USB-5203 to warm up for 30 minutes before taking measurements. This warm up time
minimizes thermal drift and achieves the specified rated accuracy of measurements.
Configuring data logging options
The following data logging options are programmable with software.
select the input channels to log
set the data format
set the start mode
set up alarm conditions
copy and convert saved binary files
delete data files
All data logging options are stored on the OM-USB-5203 in non-volatile memory in EEPROM, and are loaded
on power up.
