Troubleshooting
11.1
USB connection and/or power supply is missing
If the status bar displays Not connected
communicate with the SPECTANO 100 device.
In this case, check whether:
•
the USB cable is connected both to SPECTANO 100 and to the computer.
the power supply is connected to SPECTANO 100.
•
•
SPECTANO 100 is switch on.
After the power supply and the USB cable are connected and SPECTANO 100 is switched on, the
status bar will show Device connected
11.2
Lost communication
The loss of power supply can cause loss of communication between SPECTANO 100 and the
computer. In this case the status bar displays Not connected
Also, other events like computer shut down or sleep can cause loss of the communication.
Note: Data loss during measurement is possible if the communication between
SPECTANO 100 and the computer is lost. In this case:
► Ensure that the power manager settings of your computer match the measurement settings so
that the computer does not shut down switches to sleep mode during measurement. Depending
on the frequency range and the measurement sequence settings, a measurement can take hours
or even days.
► After the communication has been lost, check whether:
o
the power supply is correctly connected to SPECTANO 100.
o
SPECTANO 100 is switched on.
After the power supply and the USB cable are connected and SPECTANO 100 is switched on, the
status bar will show Device connected

Measuring small capacitances – increased noise level
If measuring of dielectric materials with a low capacitance shows an increased noise level, check
whether the guard and the ground in your measurement system are separated. Separate the guard and
the ground, if needed. Shield the test cell and the test system and ensure that the cabling is also
shielded.
For more information on how to increase the capacitance of your test sample or on test setup
improvement, see our application notes available at www.omicron-lab.com.
