Troubleshooting
11.1
USB connection and/or power supply is missing
If the status bar displays
Not connected
, then
SPECTANO Analyzer Suite
does not
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
.
11.3
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.
