IVI driver range problem agilent multimeter

[srapp@moog.de]

Hello,

I have the following problem with the IVI driver for a agilent multimeter:

I want to have a resolution of 4,5 digits, so I switch the resolution to 0,001. Then I configure the multimeter via GPIB and measure the value. the measurement value is floating around about 0,6 V.

When I switch the multimeter resolution manually (via frontpannel) to 5,5 digits and then back to 4,5 digits the measured value is constant.

what can be the problem

Hi Samuel,

I have a few questions:

Where do you switch the resolution to 0,001 (would be 3,5)?

What do you configure via GPIB, the resolution?

By configuring the resolution manually, what do you mean by frontpanel, the multimeters or a LabVIEW front panel?

Where do you read the measured value, in LabVIEW? (tried to change numeric display settings?)

Regards Christian

Hello,

-I switch the resolution to 0,001 from teststand via IVI driver (would be 4,5)

-Yes I configure the resolution via GPIB .

-By configuring the resolution manually I mean the frontpanel of the agilent multimeter

- I read the measure value in teststand with help of IVI driver, but I also see the measurement value floating on the frontpanel of the     agilent multimeter when I switch the multimeter to local after it was configured from teststand with IVI driver.

Hi Samuel,

Please tell me also which agilent instrument, and which driver do you use!

I am using the Agilent 34401A multimeter

I  am using the IVI which can be downloaded the installer packages name of the driver is hp34401a_MS.msi

Hi,

A few months ago i also controlled a 34401A via GPIB, without any problems, so maybe its a driver problem!

Try to download and install another driver automatically und LabVIEW Tools>Instrumentation>Find Instrument Driver

Hello samuel,

I am the developer of 34401A IVI driver.

Do you configure the multimeter with hp34401a_ConfigureMeasurement (vi, HP34401A_VAL_DC_VOLTS, 10.0, 0.001) API?

Please send your code to me so that I can figure out the problem. My email address is zhjiang@ni.com

Thanks
