Selecting Setup Absorbance vs. Time will bring up the following dialog
box:
Using the pull-down menus, you can enter Experiment Length (in
seconds, minutes, or hours) and Sampling Rate. A maximum of 30,000
points can be collected.
You can also access the Setup Absorbance vs. Time Experiment dialog
box by using the toolbar.
Digital spectrophotometers may connect directly to a computer running
Spectro Pro via a special cable (see Appendix C). Analog
spectrophotometers must communicate with Spectro Pro via one of the
following interfaces: a Vernier LabPro, a ULI, or a Serial Box Interface.
The Interface dialog box allows you to force Spectro Pro to search for a
compatible interface. The current communications channel is shown in
the drop-down menu. If the most recently used interface is not detected,
“Select port to scan” appears as the Interface. To choose a channel,
select it from the list. That port will be scanned for an interface.
Successful communication with an interface is shown by the identifying
information; here, a LabPro is connected to COM1. Click on OK to
confirm the search and close the dialog. The icon associated with the
interface will appear on the toolbar. The next time Spectro Pro is started
the selected port will be used. If no interface is detected on the selected
port, the OK button will change to Scan. Use this button to re-scan the
currently selected port, or click Cancel to leave the dialog without
searching for an interface.
