Troubleshooting measures
When operating in
subrange of ±3 V
significant distortions
occur during signal
conversion,
meanwhile, the
operation of E20-10
module is restored
either upon switching
off and on the supply
voltage of E20-10, or
upon programmed
switchover of the
measurement
subrange
in your measurement design
voltage supplied to E20-10
input exceeds significantly
measurement range of
E20-10 having closed to
edges ±10 V of maximum
permissible voltage at E20-
10 input or having exceeded
these edges.
Take measures to limit input voltage of E20-10
signal.
If you provide detailed technical data on your
measurement design
will
consult on this issue.
8.1. How to be consulted
A telephone call to
L-CARD
and explaining the problem "in layperson’s terms" is, as a rule, a
pure waste of time (both yours and another person's) because the specialist needs initial data
describing your situation. There is a great amount of these initial data
(you can not remember all), so
it is extremely necessary to send them to
L-Card
in writing (email, website conference, fax,
regular mail or personal delivery to
L-Card, see the addresses on the reverse side of the title page of
this book)
.
The following initial data describing your situation are required:
•
Your name and contact data.
•
E20-10
serial number (see on the module body or relevant program-accessible information).
•
What computer (which chipset) is used and what type of operating system is used.
•
What software and what device driver are used (indicate the version and other information
which would help us to understand you).
•
What software user settings of
E20-10
are used (ADC conversion frequency, input subrange,
the number of channels sampled, duration of interframe delay, ADC synchronization and
data acquisition start modes).
•
External connections diagram (textual description of connections or a diagram sketch),
numbers of connectors contacts and approximate length of wires must be specified.
•
What signal sources are used and what output electrical parameters they have.
•
Estimation of levels of the signals applied to the product contacts, which type of signal is
used (point out specific parameters of signal, if known, pulse or sinusoidal, stray or
periodical, frequency bandwidth).
•
Under which conditions the product is being handled (laboratory, production).
•
Describe the configuration of grounding circuits of the computer, if the sources of signals are
grounded and how.
•
Finally, describe the observed negative impact providing this description with at least any
metric values or assessments!
If you do some work and provide these complete initial data, our specialist will be able to send
you the most accurate and correct answer within the shortest possible time!
