Logger Pro can collect mass data from certain models of Ohaus balances. An up-to-date list of supported models can be found at www.vernier.com/probes/Ohaus.html
Installing the Ohaus USB Drivers
If you are connecting an Ohaus balance to your computer using a serial connector (Windows only), no special drivers are needed. If you are connecting a balance to your computer using a USB connector, read the following instructions for your particular operating system.
Important: Do not connect your Ohaus balance to your computer before Logger Pro is installed. If a balance is connected to the computer before Logger Pro is installed, it may have trouble finding the correct drivers.
Windows XP
The required drivers will be automatically installed in Logger Pro.
Windows 2000
1. Connect a balance to the computer using the USB cable. The balance should be powered and turned on.
2. A New Hardware Wizard will launch.
3. Proceed through the Wizard until it asks you to insert a CD to locate the appropriate drivers.
4.
Insert the Logger Pro CD into the CD drive. If a Logger Pro CD is not available, point the Wizard to ...\Program
Files\Common Files\Vernier Software\Ohaus drivers. Note:
If at any time the Logger Pro installer starts to launch, simply
click Cancel to exit.

time while

Collecting Data Using an Ohaus Balance
1. Launch Logger Pro.
2. Connect the Ohaus balance to the computer.
3. Choose New from the File menu.
4. If the Ohaus balance is not automatically
identified in the toolbar (look for the Ohaus icon and
a mass reading), choose Connect Interface from the
Experiment menu and select the correct port. USB will usually use COM 4
and serial will use its assigned COM number. If the balance is still
not found, try selecting other COM ports from the list until you find
the one that works.
5. You are now ready to collect data.
