Troubleshooting problems

Symptom

Possible Cause

Possible Solution

Board does not
respond

The board configuration is
incorrect.

Check the configuration of your device driver to
ensure that the board name and type are correct.

The board is incorrectly
aligned in a PCI
expansion slot.

Check that the slot in which your KPCI-3101–4
Series board is located is a PCI slot and that the
board is correctly seated in the slot.

The board is damaged.

Contact Keithley Instruments.

Intermittent
operation

Loose connections or
vibrations exist.

Check your wiring and tighten any loose
connections or cushion vibration sources.

The board is overheating.

Check environmental and ambient temperature;
consult the board’s specifications in the
Appendix of this manual and the documentation
provided by your computer manufacturer for
more information.

Electrical noise exists.

Check your wiring and either provide better
shielding or reroute unshielded wiring.

Data appears to
be invalid

An open connection
exists.

Check your wiring and fix any open
connections.

A transducer is not
connected to the channel
being read.

Check the transducer connections.

The board is set up for
differential inputs while
the transducers are wired
as single-ended inputs or
vice versa.

Check your wiring and ensure that what you
specify in software matches your hardware
configuration.

Computer does
not boot

Board is not seated
properly.

Check that the slot in which your KPCI-3101–4
Series board is located is a PCI slot, that the
board is correctly seated in the slot, and that the
board is secured in the slot with a screw.

The power supply of the
computer is too small to
handle all the system
resources.

Check the power requirements of your system
resources and, if needed, get a larger power
supply; consult the board’s specifications in the
Appendix of this manual.

System lockup

Board is not seated
properly.

Check that the slot in which your KPCI-3101–4
Series board is located is a PCI slot, that the
board is correctly seated in the slot, and that the
board is secured in the slot with a screw.
