Troubleshooting
If you experience problems with the software or are obtaining unusual or unexpected data, please
do the following:
•
Try shutting down other programs on your PC or restart your PC.
•
Try the steps outlined in 6.1.1 and 6.1.2 below.
•
Try unplugging the cable(s) at the probe(s) and reconnecting the cable.
•
Call Technical Support in Portland, OR at (503) 794-4073 or Fremont, CA at (510) 490-2150
for advice.
6.1 “No Probe” displayed in temperature display box.
If the software launches (comes up) but says
Offline or No Probe,
this probably means that the
probe is not connected. If the probe
is
connected, however, do the following:
•
Check the cabling. Be certain that the
probe, power supply
and
interface box
are all
connected and fully plugged in.
•
Is the green LED on the back of the probe lit? This indicates that the probe head has power.
•
Is the green LED on the interface box lit? This indicates that the interface box has power.
•
Check that the correct COM ports on the computer are being used. In the
Options
menu,
select
Connections
to view which COM port(s) are available and which are checked.
•
Try unplugging the cable(s) at the probe(s) or interface box and reconnecting the cable.
•
If necessary, please contact BASF Temperature Sensing for additional help.
6.2
Data Does Not Agree With Expectations
The most common sources of measurement errors are listed below, in their approximate order of
importance.
1.
Incorrect calibration factor entered under probe setup.
2.
Incorrect emissivity settings.
3.
Background or scattered light entering into the collection optics.
4.
Transmission of light (through the wafer or target object).
5.
Changing emissivity of the object.
6.
Dirty collection optics, deposition on the lightpipe.
7.
Non uniform furnace.
8.
Incorrect transfer function entered under probe setup.
9.
Dirty viewport or incorrect transmission factor entered under probe setup.
10.
Cracked or Broken lightpipes.
Every application has its own set of measurement challenges and problems so the order may vary
depending on the application. BASF’s technical support staff is available to help with these
issues.
