Contactproblems with HP 34401A Meter

I've got some troubles with my HP 34401A Multimeter.
I can't get any connection to the meter. The address is matching, the
GPIB-cable is ok. I can't find any errors.
The properties in the VI do not make any changes in the meter.
What can I do?

Best regards

Need a little more information. Are you using an NI gpib card? Is it configured
correctly? From Measurement & Automation Explorer did you do a scan for instruments
and did it find it? Is the meter the only instrument on the bus? What version
of LabVIEW are you using? Are you using the HP34401A Getting Started.vi that
comes with LabVIEW or something else?

When I get completely stuck with GPIB I usually try to make it work with
IBIC first. IBIC is the GPIB interactive control . If you have
Measurement and Automation Explorer you can get to this through that,
otherwise, try to find and run "ibic.exe". There is too much to explain
with regard to how to use it - you'll have to study the help files (type
help at the command prompt). But here's what I might do just to see if
communication is possible at all:

ibfind gpib0 // initialize gpib board
ibdev 0 2 0 7 1 0 // you may choose different params here - check the
help
ibonl 1 // place the device on line
ibln // if this returns TRUE then your gpib card
is aware of the device on the bus
ibwrt "id?"
// or *IDN - check your device's manual for
instruction syntax
ibrd 200 // read up to 200 characters - this should
return the device's response
q // quit

good luck, Vinny

Hi

You can use the measurement and automation explorer to see if the instrument
isthere

Click on devices and interfaces in the explorer. If the GPIB device doe not
show up, chances are that the GPIB card is not installed. Try reloading the
driver at that point
